We guarantee you one of the best scientific and intercultural experiences, as you will have the chance to meet internationally reknowned speakers from all over the world. Our younger colleagues will also share their work, bringing a breath of fresh air with their presentations and posters. The 4th edition of the Romanian Orthodontic Association Congress is an excellent opportunity for all of you to discover Iasi, a very important city in the Romanian history, also known as "city of great love stories", "city of new beginnings", "cultural center of Moldavia", "an open air museum", a place where every corner evokes a personality, a unique event, a legend, a part of a myth, where every stone talks about the past. Your response to this fourth edition of the congress is overwhelming: a total of 65 abstracts for oral and posters presentation were submitted. The conference programme is dense and rich, offering a considerable variety of topics covered. As in previous years, the great Romanian hospitality will make this a congress to remember, including social and networking activities that are aimed at forging collaboration and exploring ideas though multidisciplinary approaches. But it will be the presentation of research that will again be the star of this congress. The associated exhibition runs in parallel with the congress and offers you the chance to get up-to-date information from companies active in your area of interests. I am grateful to our exhibitors for their interest and support for the congress! I hope you find this congress both interesting and stimulating and that you enjoy meeting up with old friends and making new contacts.

A further complication is that it is often difficult to detect the condition on conventional radiographs, such as intraoral and panoramic films, because of superimposition of the malpositioned canine. Especially when the canine is buccal or palatal to the incisor root, the injury may be obscured. Even in cases without overlapping teeth, resorption on the palatal side of the incisor root may be difficult to detect on intraoral radiographs. In cases of ectopic, impacted canines, associated root resorption of the adjacent maxillary incisors is a serious complication which may lead to extraction of incisors, or time-consuming and expensive treatment, including surgical exposure of the canine and orthodontic repositioning of the maxillary teeth, or both. When root resorption occurs, various factors determine the choice of therapy for the particular child, not least of which is the severity and site of the resorptive lesion on the incisor root. Thus, orthodontic treatment planning should include detailed examination to determine the presence of resorption of incisor roots and if so, the site and severity of the resorption.

Orthodontic therapy became a common therapy in the 21st century. More and more people , different ages , are seeking for orthodontic treatment in order to get a better dental and facial appearance. The orthodontic treatment involves not only the clinician, but also the orthodontic technician. The orthodontic laboratory is a continuous presence from the first visit of the patient , when study casts are taken, up to the end of the active treatment, when retainers are delivered. Depending on the orthodontic strategy, the laboratory is asked to provide different types of appliances, both removable and fixed. In order to obtain the maximum benefit for the patient, the orthodontic team should promote the highest standards of practice and advance the knowledge of orthodontic laboratory and clinical techniques. Loredana Golovcencu is lecturer at the Department of Orthodontics, University of Medicine and Pharmacy "Gr.T.Popa" Iasi. She graduated in 1993 from Faculty of Dentistry, University of Medicine and Pharmacy of Iasi and she became specialist in Orthodontics in 1998. Dr Golovcencu completed her PhD studies in 2008 at the University of Medicine and Pharmacy "Gr.T.Popa" Iasi, Romania. Dr Golovcencu has numerous papers related to her main research interests , the third molar, dento-facial orthopaedics and orthodontic appliances. She attended many courses and internships in Romania, UK, Germany and USA and she had oral presentations in over 50 national and international conferences. Loredana Golovcencu 18 Abstract Book THE REMOVABLE ORTHODONTIC APPLIANCE – PRINCIPLES HIDDEN WITHIN THE ROUTINE – Anca Gorgos—Dental technicien Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Iasi, Romania The basics in creating an orthodontic appliance has at its core the efficient communication between orthodontist and specialized dental technician. Creating a specific design (a treatment plan) that is perfectly adapted to the case, combined with the accuracy of the technical execution, guarantee the finality of a proper orthodontic appliance. The presentation that is to take place during the 2013 ARSW Congress is directed primarily at dental technicians. Its main purpose is underlining the common fundamental principles that have to be applied rigorously and constantly during the technical steps taken while creating orthodontic appliances. These principles are “small secrets with great results”, known by everybody, but that are exposed to the risk of being treated superficially or even omitted. The consistency of applying these principles makes the difference between “acceptable” and “impeccable”. Within the context of the technical execution algorithm we have defined aspects that are related to the accuracy of each step, starting with the correct plaster model, continuing with the understanding and visualizing of the treatment plan, up to the finished product that has to offer a special value to the aesthetics of the orthodontic appliance. Deciding upon the retention areas, identifying and taking advantage of the already existent retentive elements, appreciating the forces that are prone to destabilize the acrylic base„plate, precisely defining the teeth upon which the active elements are applied and the direction of the orthodontic forces; all must be treated as vital actions towards successfully finalizing an orthodontic appliance. Starting from the fact that each orthodontic appliance is a unique product or, as we say, “for each patient, the right appliance”, this presentation promotes the idea that, by correctly and consistently applying the basic principles, together with the experience of the dental technician, all classic elements can be adapted to the specific requirements of each case. This also means innovation and the willingness to put it into practice. THE TWIN BLOCK IS A REMOVABLE, FUNCTIONAL APPLIANCE. Dr. Cosmin Polefka, Cosmin Ana—Dental technicien It is made up of two components, an upper and lower plate, which works together to posture the lower jaw forward. This frees up the “locked-in” lower jaw and encourages it to grow to its fullest potential. The upper (and sometimes lower) plate may also have an expansion screw to widen the arch. The Twin Block appliance can be used on people of all ages, but it is usually used in children who are in their growth phase, to treat an underdeveloped lower jaw. It is usually a “phase 1” appliance and is followed by braces (phase 2) or a retainer. Our presentation will help you to understand how is made and how it works. NURSE‘S ROLE IN PREPARING OF SMALL PATIENT FOR DENTAL THERAPY 1 2 3 Medical nurse Rodica Ciobanu , Medical nurse Gabriela Văleanu , Dr. Maria Voroneanu 1.2 Emergency Clinical Hospital "St. Spiridon ", Iaşi; 3University of Medicine and Pharmacy Iasi, Romania ABSTRACT: A solitary therapy is not enough for 100% in pediatric dentistry practice, but a combination of several factors has a positive cumulative effect: mental preparation, pharmaco-therapeutic sedation and locally analgesia. Psychological and drug preparation (pre-anesthetic - premedication) have as main objective intraoperative pain control (it is done by locally analgesia) but mainly psychological reaction to pain control. Under these conditions, preventing and combating pain as a primary source of fear which banish the child from the dental office, is a very important objective for the dental team. Although, at the time of 2013 the role of nursing-as member of dental team is not well defined nor properly legislated, it is and should be the first contact for the small patient with dental area. It’s ability to identify "problem patient", anguish, and it’s professional attitude regarding these patients may increase the efficiency of therapeutic act, providing to the dentist a patient which is already familiar with therapy, calm and cooperative. 19 Abstract Book IS CANCER IN THE ORO MAXILLO FACIAL TERRITORY A FATAL DISEASE? Turcu Dorina - Medical nurse Emergency Clinical Hospital "St. Spiridon ", Iaşi Summary At the end of the 19th century William Osler said that the mouth represents a real mirror of the human body, a fact admitted by the whole medical world and not only by it. This is to say, that a great number of diseases affecting various organs and systems in the human body can be suspected or diagnosed by the mere clinical check up of the oral cavity. But this entrance door, that is the oral cavity, has its own various and extremely severe diseases. One of these is the terrifying disease – cancer. At this level cancer can occur on the lips, tongue, mouth floor, gums, the inner lining of cheeks and on the soft palate. It is assumed that there are a number of factors and cofactors that induce cancer which have their origin in the environment which lead to local and general modifications favoring cancer with different localizations. Smoking and alcohol intake are the causes of cancer in more than 90% of cancer in the oral cavity. Can oro-maxillo facial cancer be cured? Yes, it can, provided it should be correctly treated in an early phase or in its less advanced stages. The known methods of treatment, so far, are: surgery, irradiation, cytostatic medication. The survival rate over a period of 5 years is 80%. In advanced stages surgical treatment associated with irradiation and chemotherapy can cure the patient giving him acceptable living conditions. What can we learn from this brief presentation? First, one should act upon the causing factors, the most common ones being: smoking, alcohol, absence of oral hygiene. “Smoking can kill”, but also ignorance and negligence. 20 Abstract Book ORAL SURGERY AND ORTHODONTICS. Anssia Kadrine Hammoumi (Algeria) Ex Assistant Professor, Member of The SFODF In our daily practice we are faced with specific clinical situations that lead us to a multidisciplinary treatment plan. Among these situations we have the cases of delayed eruption that require surgery in order to expose the teeth. We also have treatments for adults with periodontal disease, where we can not intervene without the previous help of a periodontist who must clean the periodontium. Last but not least, we have the case of distal kktooth loss where there is loss of anchorage and where mini screws for anchoring are needed. All these situations make us grateful to our fellow surgeons, because without them many cases would not be accessible for us. Dr Anssia Kadrine Hammoumi graduated in 1979 the Faculty of Dental Surgery ORAN (Algeria) In 1983 DEMS ODF in the Faculty of Dental Surgery ORAN. Between 1983-1991 he was Assistant Professor in Tlemcen (Algeria) and member of the National Teaching Committee between 1985-1991. In June 1991, Dr Anssia Kadrine Hammoumi began his private practice.

First, we present what does it mean a profession as compared with an ordinary job, and apply this understanding to dentistry. We analyze the relationship between professionalism in dentistry and the four ethical principles: respect for patient autonomy, beneficence, non-maleficence and justice. Finally we explore and find solutions for the tensions between dental professionalism and dental ethics. Mr. Oprea's disciplinary area is bioethics. He has PhD degree from University of Adelaide, South Australia and a Master of Art in Bioethics from Case Western Reserve University in Cleveland, USA. Liviu Oprea is experienced in the qualitative research of doctor-patient relationship and of self-management technologies. He has a special research interest for ethical issues in primary chronic care and public health ethics. He is also experienced in interdisciplinary teaching in clinical ethics and public health ethics. Liviu Oprea published his research in 10 papers in peer reviewed ISI journals and two books.

The orthopedic treatment can be taken into consideration as a solution in early detected cases, while the surgical- orthodontic approach is suitable in the end of the bone growth. Improving the intermaxillary skeletal discrepancy in a sagittal direction depends on the possibility of influencing the bone and muscle growth process. The achievement of the dentoalveolar compensation of the bone discrepancy, or the improvement of the existing one offer the possibility of orthodontic correction of class III incisal relationship. This implies the protrusion of the upper incisors, or the protrusion of the upper incisors and the retrusion of the lower incisors, or only the retrusion of the lower incisors. Choosing one type of appliance depends mainly on the age, skeletal pattern, presence of the transverse maxillary deficiency, degree of the overbite and associated disfunctions. For the treatment planning, an useful instrument is the cervical vertebrae maturation method; the purpose is to synchronize both growth period and functional therapy. In this study I investigated the orthodontic and orthopedic treatment solutions of 25 patients with class III malocclusions by using different functional appliances ( trainer I.3, cemented lower front tray, Frankel III appliance, Balters III appliance, lingual arch shield Quadhelix), as well as mento- cephalic traction or Delaire facial mask. Thorough investigation of the clinical case, choosing the optimal solution to obtain psalidodontic incisal relationship and stabile molar relationship, correction of the tongue position, as well as monitoring the evolution of the dento- maxillary system till the end of the bone growth are important steps in functional therapy of class III malocclusions. AESTHETIC CRITERIA TO EVALUATE FACIAL PROFILE IN A POPULATION OF CENTRAL ROMANIA REGION Chibelean ( Cires-Marginean) Manuela, Jurcă Anamaria, Păcurar Mariana Department of Paedodontics and Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy TgMures, Romania Objectives. The aim of the study was to measure the linear parameters that define the soft facial profile of a sample of the population in the centre of Romania and to compare the differences between males and females. These values could be useful in elaborating the aesthetic treatment goals for the population in this area. Material and methods. 50 subjects were included in the study – patients and students of UMF Tg-Mures (29 females and 21 males) between 18 to 28 years of age, having dental class I and well-balanced profile. The facial profile photographs were taken in the natural head position (NHP). The anthropometric points were located and seven horizontal linear variables that characterize a harmonious profile were traced and measured, distance between: true vertical line-Glabella (TVL-G), true vertical line-nasal tip (TVL-NT), true vertical line- point A (TVL-A), true vertical line-upper lip (TVL-UL), true vertical line-lower lip (TVL-LL), true vertical line-point B (TVL-B), true vertical line-Pogonion (TVL-Pg). Results. The values measured for the males and the females were compared. To compare the genders the tstudent test was used. Two soft tissue profile parameters were significant different between genders: TVLnasal tip (NT) and TVL-point B (p<0,005). This indicates that males had, on average, a slightly greater nasal prominence and a deeper labial sulci compared to the females. The frontal segment (TVL-G), the upper lip segment (TVL-point A, TVL-upper lip) had, on average, same values in both genders (1,28 mm).The lower lip (TVL-lower lip) had bigger values (+ 0,99 mm) in females. Conclusions. Differences between the two genders were noticed, two measurements were statistically significant different showing that the male had greater nasal prominence and deeper labial sulci while the female had a lower lip more prominent. The upper lip had similar values. These results show that for the population in the centre of Romania the treatment objectives are different for females and males. Key words: facial profile, photographic examination, linear parameters.

CEPHALOMETRIC STUDY Dana Feştilă, Mircea Ghergie, Alexandrina Muntean 1, Alin Şerbănescu Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Cluj-Napoca, Romania; 1 Department of Pediatric Dentistry, Faculty of Dental Medicine, University of Medicine and Pharmacy Cluj-Napoca, Romania Subjects and method: 30 patients with class II/1, 13 boys, 17 girls between 8-12.5 years of age, mean age 10.4±1.3, treated with functional therapy for 2.3±0.7 years long. Two lateral cephalograms, initial and final, were traced, compared and overlaped on cranial base with sella point registered, for each patient. The interpretation was made with Onyx Ceph. TM.2.7 program, using Burstone, McNamara, Rickets, Tweed, Wits, Holdaway and soft tissue facial analises and comparing the values of the variables. Results: Soft tissue facial profile depth changed statistically insignificant. Soft tissue facial profile angle increased with a mean value of 8.630 (p<0.001) because of mandibular advancement. Nasal-labial angle decreased from 1180 to 113.630, with a mean value of 4.370 (p<0.01) which is close to normal. Upper lip thickness increased from 10.68 mm to 12.08 mm, with a mean value of 1.18 mm (p<0.01). Lower lip and soft chin thickness changed statistically insignificant. The length of the lips increased with a mean of 1.63 mm for the upper lip and 3.63 for the lower one (p<0.001). Lips position regarding the esthetic line changed as follows: the upper lip moved in the back of the line with a mean value of 1.33 mm (p<0.001) and the lower lip moved backward with 0.60 mm (p<0.05), but remains in front of the esthetic line. Labial-mental fold depth decreased slightly, with 0.97 mm (p<0.05) and nasal-labial fold changed statistically insignificant. Conclusions: The convexity of the soft tissue facial profile was diminished at the end of functional treatment mainly because of changes in lips position and thickness, especially of the upper lip and less because of soft chin advancement. Although the sagittal discrepancy was importantly reduced through skeletal and dentoalveolar changes, soft tissue profile does not follow them in the same manner. ASSESSMENT OF FUNCTIONAL THERAPY EFFECTS ON FACIAL AESTHETICS 1 Alexandrina Muntean1, Michaela Mesaros , Dana Feştilă2, Anca Mesaros3 1 2 3 Department of Paediatric Dentistry, Department of Orthodontics, Department of Dental Propaedeutic and Aesthetics, Faculty of Dental Medicine, University of Medicine and Pharmacy Cluj-Napoca, Romania Aim. Facial aesthetics is perceived in our days by children and adolescents as synonymous with social acceptance and success. In this study we want to evaluate facial aesthetics, for patient undergoing orthodontic treatment with functional appliances, correlated withratios indicated in literature. Material and methods. We selected 60 patients aged between 6 and 12 years treated with functional appliances in class II malocclusion. Facial aesthetics wasassessed in relation with the nose, lips and the chin on standard photography. We evaluate facial proportions at the beginning and during the treatment using specific index: upper face-face height, lower face-face height, mandibulo-face height, mandibulo-upper face height, mandibulo-lower face height, nose-face height. We monitoredalso patient compliance related with facial changes. Results. Attractive face and straight teeth are essentials for positive attitude and confidence, but there is not direct connection between individual perception and the malocclusion. Facial attractiveness is a major concern for our patients, especially for girls (69.6%). Verticalfacial balance reveals to be an important element observed by our patient and turn in a key factor for treatment compliance. Patients approached in early mixed dentition perceived only a small amount of facial aesthetics improvement. Because at this age the correlation between personal observation and the anomaly severity is not a linear one, abandon or partial success were observe in a great majority of cases treated in this period (28.9%). Conclusions. The main goal of orthodontic treatment is to achieve a well-balanced and proportional face in abest possibleocclusalrelationship.Functional treatment success necessitates positive attitude and intrinsic motivation in order to accomplish a perfect balance between aesthetics and functionality. 24 Abstract Book DIGITAL PHOTOGRAPHY IN ORTHODONTICS Andreea Jianu, Victor Boboc, Maria Popa; Faculty of Medicine Sibiu, Romania Aim, material and methods: We all know the importance and benefits of dental photography as a clinical examination for orthodontic practice, but times have certainly changed.Now,with more emphasis on the achievement of balanced facial harmony and smile esthetics for our patients, in additon to the traditional orthodontic goals, the need for proper clinical photographic records of the orthodontic patient has become essential for adequate tratment planning and follow-up. Clinical requirements for photographic records: Digital Camera: a compact one or a DSLR Flash: Point Flash or a Ring Flash Macro Lens or Macro Function Special Cheek Retractors Dental Photography Mirrors For a maximum benefit or information, there should be a minimum of nine photographs: four extra-oral, five intra-oral. Extra-oral: face-frontal; face-frontal; profile; 45° profile Intra-oral: frontal – in occlusion; right buccal – in occlusion; left buccal – in occlusion; upper oclussal; lower occlusal Results: A good quality of an investigation method in orthodontics, beyond study models and radiographs records, that studies the patient in a „social” setting and reveals the start point of treatment. Conclusions: Why going digital? Because we live in this digital age, because the ease of use of such cameras, no need to develop photos, early checking of the records, and cost-effectiveness ORTHODONTIC THERAPY OF ATYPICAL CASES Anca Georgescu - Constanta, Romania, Mircea Georgescu - Brasov, Romania Private practice The purpose.

Tooth eruption is a genetically regulated growth process, being the last stage of odontogenesis. [1] Based on the changes occurring in the tooth bud, odontogenesis comprises 4 stages: dental lamina, the bud stage, the cap stage and the bell stage.[2] There are only a few studies dealing with Ki67 and Aquaporin1 (AQP1) expression of human tooth buds. AQP1 is a membrane protein, a water channel, occurring especially in renal cells and erythrocytes. Ki67 is a non-histonic protein discovered in 1991.[3,4,5] The aim of the study: to describe the proliferation occurring in tooth buds of different stages of ontogenic development using Ki67 and AQP1. Material and method. For the purpose of this study: tissue samples containing tooth buds were removed from the incisor, canine and molar areas of human fetuses in different stages of development (weeks 9-10, 12-13, 13-16, 21-24). The samples were formalin fixed and paraffin embedded, then sectioned using a microtome. Antigen retrieval was performed using moist heat. Primary antibodies were applied: Ki67 (Diagnostic Biosystem, Pleasanton, USA, clone SP6), conc. 1/100; AQP1: Anti-AQP1, Histophatology Ltd., Hungary, clone 1/22, conc. 1/600). The following secondary system was used: UltraVision LP Large Volume Detection System HRP Polymer (Ready-To-Use) (Thermo Scientific, Fremont, CA), according to the manufacturer's instructions. The resulting slides were photographed and quantitatively evaluated. Results . Ki67 expression decreases with the developmental stage of the tooth bud. This aspect has been observed in all layers, in the inner enamel epithelium (IEE), preameloblast (PB) and ameloblast (AB) layer, the outer enamel epithelium (OEE), the stratum intermedium (SI), the stellate reticulum (SR), and the dental papilla (DP), outer cells of dental papilla (DP1), the odontoblast layer (O), central cells of dental papilla (DP2) and in dental pulp (P). (Table 1)(Figure 1,2,3). Comparing teeth of similar developmental stages, but different areas (weeks 21-24, incisor, canine, molar), the most intense proliferation is in the molars, followed by proliferation in the canines, and the weakest proliferation is seen in the incisors. (Figure 4,) We detected AQP1 expression in all layers of the tooth bud. (Table 2) In case of incisors, AQP1 expression decreased in dental papilla, outer cells of dental papilla, odontoblasts, in inner cells of dental papilla and in the dental pulp from weeks 9-10 to weeks 21-24 of intrauterine development. In case of other relationships we did not find any significant differences.( Figure 5) Discussions. A study on human fetuses has been performed by Guven et al. who compared weeks 13, 16, 21 and 30 of intrauterine development, and obtained similar results. They described a decrease of Ki67 expression in the papilla and the outer and inner enamel epithelium as the developmental stages were more and more advanced. In case of the stellate reticulum and outer enamel epithelium they did not see any proliferation after week 21.[6] In a study performed by Wang et al. on 18 week old fetuses AQP1 expression has been demonstrated in the tooth buds.[7] Conclusions. Ki67 expression decreases with advancement of the developmental stage of the tooth bud. AQP1 is present in all layers of the tooth bud. REVIEW OF THE DIAGNOSIS AND THE MANAGEMENT OF MAXILLARY IMPACTED CANINES Alin Serbanescu, Mircea Ghergie, Dana Feştilă, Adina Tufană Faculty of Dental Medicine, University of Medicine and Pharmacy Cluj-Napoca, Romania Aim: Using different publications and studies, the authors made a review of the clinical and radiological diagnosis of the maxillary impacted canines, of the interceptive therapy used for preventing and treating impacted canines and the surgical and orthodontic management. Methods: The authors examined multiple clinical and radiological studies and selected those related to the prevalence, etiology and diagnosis of maxillary impacted canines, as well as those regarding a good orthodontic and surgical management. Results: The possible impaction of maxillary canines could be diagnosed at an early age and clinicians can prevent it through a good clinical and radiological diagnosis, and an appropriate interceptive treatment. The surgical techniques depend on the labial or palatal impaction and the orthodontic management varies on every clinician’s experience. Conclusion: Maxillary canines’ impaction is quite frequent and clinicians should be ready to manage it. With an early diagnosis, interceptive treatment and appropriate surgical and orthodontic treatment, impacted maxillary canines can erupt and can be guided in their right position on the dental arch. 26 Abstract Book THE EFFECT OF LOW LEVEL LASER THERAPY ON ORTHODONTIC CANINE RETRACTION RATE Adriana Monea1, Mariana Păcurar2 , Doru Roman2 1 Department of Odontology and Periodontology, Faculty of Dental Medicine, University of Medicine and Pharmacy Tg.Mureş, Romania 2 Department of Paedodontics and Orthodontics, Faculty of dental Medicine, University of University of Medicine and Pharmacy Tg.Mureş, Romania Background. Modern orthodontic therapy continues to advance, leading to improvements in the quality of care. The use of low level laser therapy in addition to orthodontic treatment was studies by several researchers, but the result remains controversial. Objective. The aim of the study was to investigate if low level laser therapy (LLLT) associated to mechanical forces stimulates the rate of orthodontic tooth movement. Material and methods The study was conducted on 10 young adult subjects who required retraction of maxillary canines into first premolar extraction spaces using tension elastic chain with fixed appliance. LLLT vas applied buccaly to the canine on the test side and using a pseudoaplication on the placebo site. Dental impressions, casts and profile teleradiographs were taken at the beginning of the trial and 10 days post LLLT treatment. Data of the biometrical progress on both sites (study and control) were statistically compared. Results. All patients showed significant higher acceleration of the retraction of canines on the side treated with LLLT when compared to the control. Conclusions. Our findings suggest that LLLT does accelerate human teeth movement and could therefore shorten the whole treatment duration. Key words: low level laser therapy, orthodontic tooth movement THE MINIMAL INVASIVE HARVEST OF THE ILIAC BONE GRAFT IN TREATMENT OF THE CLEFT PALATES Victor Costan, Irina Nicoleta Zetu Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Iasi, Romania The bone grafting in cleft palate is a very important step in treatment of the cleft palate. Usually, the harvesting of the iliac bone is a traumatizing procedure, with approximately 2 weeks period of healing. Special devices permit minimal invasive collecting of the iliac bone, with minimal consequence on recovering of the patient. These new approaches permit, in our experience, an easiest recommendation of bone grafting. 27 Abstract Book PERIODONTAL IMPLICATIONS IN THE ORTHODONTIC DIAGNOSIS AND DURING TREATMENT OF MALOCCLUSIONS Ursut Anamaria, Mihaela Chis, Maria Harceaga, Daniela Cornea Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Cluj-Napoca, Romania. Aim of investigation: Discovering the periodontal lesions in the initial orthodontic evaluation as well the causes that may lead to these changes during the treatment. The solution to these problems is the multidisciplinary approach. Subjects and methods: Three clinical cases are presented in order to highlight the periodontal correlations with orthodontic treatment. Case 1: 7-year-old male patient with anterior crossbite ( 1.1-4.1) and vestibular gingival retraction localized in the inferior central incisors area. The orthodontic treatment managed to remove the anterior crossbite and also the oclusal trauma of 4.1. Case 2: 21-year-old female patient with severe maxillary compression, class II/1 malocclusion and vestibular gingival retraction (3 mm) in the 4.1 area, high insertion of inferior labial frenum and poor oral hygiene. The extraction decision of 4.1 was determined by the severe periodontal suffering of this tooth, in order to obtain the necessary space. Case 3: 14-year-old female patient with severe crowding and functional right mandibular deviation. The patient developed, during orthodontic treatment, a gingival hypertrophy that could have been caused by poor oral hygiene, the fixed appliance and insuficient dosed forces, along with the pubertal hormonal imbalance. Results: The orthodontic evaluation of the patient must be done after a complex protocol, with the active involvement of the periodontist, not only for the periodontal certainty diagnosis, but also for the choice of therapeutic solutions and surveillance of malocclusion evolution. TENSILE STRENGHT OF AS-RECEIVED AND RETRIEVED STAINLESS STEEL ORTHODONTIC ARCHWIRES Silvia Izabella Pop1, Mariana Pacurar1, Mircea Dudescu2, Dana Critina Bratu3 1 Department of Paedodontics and Orthodontics, Faculty of Dentistry, University of Medicine and Pharmacy Târgu-Mureș, Romania 2 Department of Mechanical Engineering, Technical University of Cluj-Napoca, Romania 3 Department of Paedodontics and Orthodontics, Faculty of Dentistry, University of Medicine and Pharmacy Timișoara, Romania ABSTRACT. Aim. This study was undertaken to evaluate the tensile strength of the new (as received) and used (as retrieved) stainless steel orthodontic archwires. Material and methods. A total number of 24 stainless steel orthodontic archwires with two different crosssection (0.016 inch and 0.016x0.022 inches) were subjected to tensile tests. An Instron Universal Testing Machine type 3366, was used to perform the tests on 12 (6 of each cross-sectional dimension) as receveid stainless steel archwires (group I) and 12 retrieved archwires (group II). The retrieved archwires were used in vivo, for a mean period of 2 month. Tensile stress at yield (0,2%), tensile stress at break and modulus of elasticity were determined. Mann-Whitney test, level of significance p<0.05 was used to statistically analyzed the results. Statistical analysis was performed using GraphPad Prism 5.0 for Windows. Results. The values obtained through tensile testing of the 2 archwire groups showed statistically insignificant differences. Group I and II exhibit similar values of tensile stress at yield, at break and modulus of elasticity. The cross sectional dimension does not modify these properties. Conclusions. Mechanical properties such as tensile strenghth of the stainless steel archwires are not influenced by a mean period of 2 months intraoral use. Key words: orthodontic archwire, stainless steel, modulus of elasticity 28 Abstract Book ORTHODONTIC APPROACHIN TREATMENT OF SAGITTAL MALOCCLUSIONS DEPENDING ON DENTITION ValentinaTrifan, Sabina Calfa, Daniela Trifan Department of Pediatric Surgery, Paedodontics and Orthodontics, University of Medicine and Pharmacy Chisinau Summary. This work reflects orthodontic approach of sagittal malocclusions depending on patient age.Sagittal malocclusion are the commonest anomalies of occlusion with aesthetic, periodontal, and TMJ consequences.( ValentinaDorobăț, 2001). The purpose of the study: to improve the efficiency of orthodontic treatment in sagittal malocclusions according to the dentition with the development of diagnostic and treatment goals. Material and methods: the study was conducted based on clinical examination,paraclinical(cephalometric analysis,biometric study,fotostatic exam) and used orthodontic therapy of sagittal malocclusions according to the dentition of 36 orthodontic patients.Orthodontic approach was carried out through orthodontic appliances,removabale and fixed.Interceptive treatmentconsists in detecting dento-maxillary anomalies of the first signs or stopping the development can be performed using the removabale appliances with combined action or function. Functional equipmentis considered by the most authors primary impact on the the facial skeleton on the child's growing, exerting influence on the mandibular condyle,suture zones,and the dentoalveolar area. Results:in the study conducted it shows, that the incidence of severe forms of sagittal malocclusions,will decrease in case of early orthodontic treatment.Application of preventive methods will reduce the morbidity of sagittal malocclusions, will contributeto reduce the need for late orthodontic treatment and enhance the changes in facial aesthetics,characteristic sagittal malocclusions.

Materials (or subjects) and methods: The experimental group was composed of 111 patients with ages between 5 and 28 years (mean value: 11.09±4.289 years), 51 boys (mean value; 10.41±2.954 years) and 60 girls (mean value 11.67±5.115 years), diagnosed with hypodontia (except third molars) at the Ambulatory of the "Sf. Spiridon" Universitary Emergency Hospital of Iasi, between 1990–2012. The hypodontia diagnosis was established by interview method, clinical examination and by ortopantomographic evaluation. The statistical analyses were performed using the SPSS 17.0 program for Windows. Results: Four categories of hypodontia were revealed of the congenitally missing teeth, a high prevalence of the premolar (mandibular and maxillary) and maxillary incisor groups, as well as the predominant presence of the mono and unidental clinical forms of hypodontia. Hypodontia was located both unilaterally and bilaterally, on the four dental quadrants. The differences between sexes were insignificant. Statistically significant correlations have been established among the number of teeth, the dental groups with agenesis and the clinical forms of hypodontia (p=0.000). Conclusions: The prejudices of congenitally absence of teeth upon the maxillary arches and also upon the dental and facial aesthetics call for an early tracing of hypodontia by dentists, for achieving an as cheap as possible therapeutical management for the patients. Even if the distribution of the congenitally missing teeth and the clinical forms are not serious in the group of population investigated here, the therapeutical implications are quite severe – according to the IOTN and the intervention of a team of specialists is expected to solve the subsequent complications brought about by hypodontia.

Dento-maxillo-facial asymmetries are complex abnormalities with wide clinical variability, diagnosis of these stringent imposing the corroboration of clinical examination data with laboratory test results. Aim. The purpose of this study was assess and quantification of dento-maxillar asymmetries in a population of children from Iasi. Material and methods. The study was carried on a number of 75 OPG from patients who presented to the Iași Paediatric Dentistry Clinic for various dental diseases. Chronological age limits for children whose panoramic radiographs were analyzed were 8-12 years. All panoramic radiographs were analyzed by Levandoski method. Results and discussions. The results of this study confirm that light dentomaxillo-facial asymmetries are encountered quite frequently in the population investigated. In patients experiencing increases in the length of a condyle, it has been often found association with increases of coronoid size on the same part, fact of particular relevance in diagnose of asymmetry. Measurement of the maxillary length has shown a significantly increased percentage for the right side in comparison to the left one. Conclusions. Levandoski analysis method of OPG represents an effective screening method for analyzing and early detection of dento-maxillar asymmetries. Key words: panoramic radiography, Levandoski analysis, children, dento-maxillary asymmetries. SKELETAL PATTERNS IN CLASS II MALOCCLUSION. TELECEPHALOMETRIC STUDY. Cristian Romanec, Valentina Dorobat Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Iasi, Romania Abstract. Class 2 malocclusion is an abnormality with high frequency, it recognizes a pluri-causal etiology, worsens with the age, presents a great diversity of clinical forms, which imposes an extensive exploration of the clinical case in order to elaborate the diagnostic and the treatment strategy. The research develops identification of the skeletal patterns in class 2 malocclusion, telecephalometric study on 52 clinical cases. The goal was to identify the skeletal patterns, their form and gravity, but also the dentoalveolar compensation phenomena in class 2 anomalies. The dento-alveolar skeletal patterns in class 2 malocclusion have been identified in our population and the pathognomonic dental, dento-alveolar and occlusal characteristics in class 2, respectively subdivisions 2/1, 2/2 have been highlighted. Key words: class II Angle malocclusion, skeletal patterns A COMPARATIVE STUDY ON THE REPEATABILITY AND RELIABILITY BETWEEN THE MANUAL AND COMPUTER -ASSISTED CEPHALOMETRIC MEASUREMENTS Mihnea Iacob1,Danut Cozma2, Irina Zetu1, Valentina Dorobat1 1 Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Iasi, Romania 2 ”Alexandru Ioan Cuza” University, Iasi, Romania Abstract: Objectives The aim of the present study was to comparatively evaluate the repeatability and reliability of the results obtained by manual and computer assisted tracing of a group of cephalometric radiographs. Materials and Methods A group of 60 initial cephalometric radiographs from 60 orthodontic patients, undertaken with the same radiological machine, was selected. The cephalometric radiographs were traced and measured using the classic (manual) method and the Orthalis cephalometric software, using the parameters of the Steiner and Tweed analysis. The measurements were repeated after a 30 days interval by the same examiner. Results The manual and cephalometric tracings presented a high degree of repeatability and accuracy. Conclusions The cephalometric software represents a useful tool for the orthodontic diagnosis and treatment planning. 32 Abstract Book POST-ORTHODONTIC GINGIVAL RECESSIONS - PREVALENCE AND ETIOLOGY Liviu Zetu, Cornelia Oanta, Alina Andronovici Department of Periodontolgy , Faculty of Dental Medicine, University of Medicine and Pharmacy Iasi, Romania The gingival recession is defined as the migration of the gingival margin apically from de enamel-cement junction. It is a common problem in adults, as approximately 8 of 10 people around the age of 50 have at least one gingival recession. The sites affected most often are the inferior central incisors, the inferior canines and the upper molars. Although the orthodontic treatment has numerous advantages for the patient (esthetic, functional), in some cases it is said to have caused gingival recessions. The aim of our study was to determine if the orthodontic movements, during the orthodontic treatment, can cause gingival recessions and what is the incidence of those recessions.

In comparison to removable functional appliances, fixed functional appliances have several advantages: (1) extremely efficient in post-adolescent and young adult patients, (2) stimulate mandibular growth, (3) independent of patient cooperation, (4) short treatment period, and (5) can be an alternative to orthognathic surgery in borderline adult Class II cases. In evidence based orthodontics the role of both the removable and fixed functional appliances will be addressed. However, emphasis will be placed on the Herbst appliance. Lecture topics: Historical and scientific background of functional appliances Appliance design and construction Short- and long-term treatment effects on: (a) tooth position and occlusion (b) mandibular growth (c) maxillary growth (d) masticatory muscle function (e) TMJ (f) facial profile (g) parodontium Anchorage problems Complications Treatment indications Early vs. late treatment Treatment of adults Stability and relapse Retention after treatment Hans Pancherz , DDS, Odont.

David Suarez Quintanilla (Spain) Chairmen of Orthodontics-University of Santiago de Compostela In our area Class II Malocclusion may be caused by deficient mandible (60%), dentoalveolar excess (10%)or a combination of these (40%). Most of the patients present rotation and mesialization of the first upper molars, a narrow upper arch, inadequate anterior guide and muscular imbalance in the Tomes Corridor. Correction often is obtained by dental distalization with or without growth modification using functional or direct orthopaedics. Our philosophy in the Class II treatment with the SWLF (Straight Wire Low Friction) technique is maximum efficiency with the minimum amount of appliances. For us is very important a new ecological vision of our treatments, using the Propioception Concept (PC) and the natural forces of the stomatognatic system of the patient (muscular forces, eruption forces, neuromuscular stimulus, etc.). The choice concerning the selection of appliances is not easy nor always clear, but we suggest (according to Johnston, 2006) that our functional appliances act by holding the teeth out of occlusion and preventing dental compensations from happening. In the Class II facial analysis is very important the evaluation of the soft tissues, the facial profile and the lower part of the nasolabial angle. We use the classical Class II diagnostic tools (2D cephalometric analysis, cast study ,etc.) but we have to be open to new technologies incorporating new diagnostic devices (intraoral scanner, electronic articulator, new virtual reality software to analyse the occlusion and to predict the result of treatment, etc.) and also new techniques/ systems/ appliances for the treatment (new functional appliances, new tools for stimulate the OTM, etc.). We have to start the treatment on time, according with the Evidence Based Treatment, and have an eclectic mind, combining functional and fixed appliances in the same phase of treatment. The use of fixed and functional appliances at the same time is used to align and distal driving of the teeth, to expand the arches, to increase the overjet ( creating enough space for the advancement of the lower incisors) and to modify dentofacial growth in Class II patients. A favourable response includes both restraint of maxillary growth and differential mandibular growth. In skeletally immature patients during permanent dentition, there is nothing wrong with a first phase of functional appliance treatment ( Bionator, Orthoflex II, FR Frankel, C-Modeler, etc.) . Using SWLF fixed appliances we don´t use the Class II elastic in the early treatment nor in the first phase. Many clinicians would like to believe that Class II elastics can influence growth as well as it can move teeth. According with W. Proffitt, the evidence indicates that growth modification in adolescents is unlikely with elastics or flexible spring devices as Forzus ©. Noncompliance approaches provide an important treatment alternative for the orthodontic management of patients with molar / dentoalveolar Class II in the maxillary (Pendulum Appliance, NiTiCoil Spring Appliances, Herbs Appliance, Jasper Jumper, Biele ©, etc.) We use different systems and techniques for the Class II treatment incorporating TADS. The use of miniimpnats simplifies the molar and incisor control in the three planes of the space. It is an excellent option for the dolicocephal patients with Class II and vertical maxilla and mandibular growth. For the second phase of treatment when we are using fixed appliances, our philosophy comprehend the use of brackets with FSC ( friction selection control) and superwires ( NiTi thermal wires, Beta III Titanium,etc.). We have a lot of specific protocols for each Class II patients according to the : age and estimate growth, severity of malocclusion, facial biotype, dental and skeletal discrepancy, compliance, etc. Graduate in Medicine.

The unpredictability of the cessation of AP and more important vertical growth, the low tongue position which cannot be effectively changed by orthodontic appliances, the mostly narrow lower alveolar crests with little bone around the lower roots which impedes proper tooth positioning, the mostly narrow maxilla, the tendency for labial gingival recessions, the lack of sufficient overbite which could eventually promise some stability for the end result of the orthodontic treatment, are all factors which often make dentoalveolar compensations a failure. This is why, more often than not, there is an indication for combined orthodontic and surgical treatment. This has to be foreseen even before growth finishing, if there are therapeutical decisions to be taken for transverse intermaxillary discrepancies or dental malpositions like ectopic canines or lower crowding.

The treatment plan can include the maintenance of space for rehabilitation by an implant-supported prosthesis. However, in many cases, it might be advantageous to close the space, especially when the gap closure provides superior esthetic results, or when the patient simply does not want to receive implant rehabilitation. Commonly, the use of TADs as anchorage is beneficial to the latter form of treatment. In some cases the TAD is - be it a miniplate or a miniscrew - crucial to achieve excellent treatment results, and then, the applied orthodontic mechanics has several specificities. This conference will tackle the treatment protocol used to close the space of missing teeth with miniplates, as well as the advantages and limitations of this treatment modality. ANTICIPATED BENEFIT– ELIMINATION CONVENTIONAL ORTHODONTIC PREPARATION FOR ORTHOGNATHIC SURGERY Conventional orthodontic-surgical treatments for the correction of dentofacial deformities comprise - after diagnosis and treatment plan - a presurgical orthodontic stage, the orthognathic surgery per se and the orthodontic finishing stage. This treatment method has also been tested by time. It has been used for decades and proved very effective. However, it has limitations because when patients decide to undergo the treatment they have to wait for almost a year and a half for the surgery. This is somewhat paradoxical since many patients who seek treatment do so motivated by the promise of aesthetic enhancement, despite the treatment's primarily functional nature. On account of this limitation, among others, since 2004 Dr. Faber has been using in his private practice a treatment methodology that anticipates surgery. After diagnosis, this protocol consists in extensively planning all treatment phases, installing the orthodontic appliance, operating on the patient and only then performing the actual orthodontic treatment. This methodology anticipates the benefits of surgery and has, therefore, been appropriately named Anticipated Benefit Method. Although the orthodontic plan is more complex than conventional treatment, surgical plans are not. Surgeons, however, should be aware of all orthodontic steps taken throughout the treatment. The purpose of this lecture is to present the rationale of this protocol. Dr. Faber is the editor-in-chief of the Journal of the World Federation of Orthodontists. He is an Adjunct Professor of Orthodontics and EvidenceBased Dentistry at the University of Brasilia. He was the winner of CDABO Case Report of the Year, for the best case report published during 2009 in the AJO-DO, and has published over than 70 scientific articles.

Niels Hulsink (Netherlands) Orthodontist, Researcher at Australian Research Myofunctional Incorrect Myofunctional habits like tongue position, tongue thrust, incorrect swallowing, mouth breathing and bad lip support, are often the cause of a malocclusion. Because of this, we have to try to correct as well the cause and not only the dental problem. If we are not able to correct the cause in this kind of cases, than the results won’t be as stable and good as we want. In this presentation most of the incorrect Myo- functional habits will be showed. We are also going to look how to recognize these habits and to find the relationship between the incorrect habit (function) and the malocclusion (form). Myofunctional therapy gives the best result if we can start as young as possible, between 4 and 12 years of age. It’s very important to correct the incorrect function first before we are willing to start any orthodontic treatment after. If we are able to start more early, the rest of the (orthodontic) treatment that will follow, will be much more easier, and the result more stable. The Myofunctional therapy gives a positive result on the function, the posture and the form in the growing child, and is therefore not an orthodontic treatment but an early treatment. Dr. Chris Farrell designs the Myofunctional Trainers. He is the owner of the Australian Myofunctional Research Company. These Trainers can have many benefits by young children in the first, mixed and permanent dentition. The design of the trainers is focussed on retraining of tongue position, tongue thrust, incorrect swallowing, mouth breathing and bad lip support. You will also see that the trainers re position the mandible and guiding the erupting teeth in some cases. My presentation will also teach you how to find the right indications and how to motivate patient and parent. In 1999 NielsHulsink started working in the orthodontic market. In the first 4 years he was involved in the innovation of a new indirect bonding system, this in cooperation with several dentists and orthodontists. During these 4 years he worked in many dental practices and laboratories while applying this system to orthodontic patients. For one year he also worked fulltime as an orthodontic assistant, bonding braces directly as well as indirectly. Since 2004 NielsHuksink has been working for Myofunctional Research Company. This company innovates and produces appliances for (early) treatments to prevent and correct the incorrect myofunctional habits that cause the malocclusion and many other problems concerning function and form. Early myofunctional treatment is essential to avoid aberrant facial growth in children. Niels Hulsink 39 Abstract Book ACCELERATED TOOTH MOVEMENT Leslie A.

Will Abstract Book MULTIDISCIPLINARY ADULT ORTHODONTICS - IN SEARCH OF OPTIMAL TREATMENT Stella Chaushu (Israel) Department of Orthodontics- School of Dental Medicine Jerusalem Orthodontic treatment is generally performed in healthy young patients with normally erupting teeth. However, in the last decade or two, the demand for adult orthodontics has increased tremendously. Orthodontic treatment in adults poses additional and, sometimes, apparently insurmountable difficulties to the clinician. There are greater challenges in planning the appropriate treatment due to restorative and periodontal limitations. Planning adequate anchorage can be extremely difficult when several teeth are missing or periodontally involved. Tooth movement in the absence of proper periodontal control may accelerate an irreversible breakdown of the periodontal support apparatus. Treatment also poses an increased social challenge and a demand for inconspicuous appliances. The presentation will review various challenging scenarios in the above-mentioned areas, and will underscore the importance of teamwork between restorative dentist, periodontist and orthodontist when planning treatment for these patients. It will offer original step-by-step solutions, employing the latest imaging modalities, “invisible” (e.g. lingual) appliances and absolute anchorage systems to make treatment feasible, simpler and more efficient, leading to predictable and rewarding results. Dr. Stella Chaushu is Associate Professor and Chairperson of Department of Orthodontics in Jerusalem, Israel. She is the coordinator of three different fields in the department: adult orthodontics, orthodontic treatment for impacted teeth and treatment of special needs children.

Sheridan and Keith Hilliard in the 90s. The real development has emerged a decade ago with the use of modeling and stereo lithography. Initially, treatments were limited to a simple realignment of the incisors with or without inter-proximal reduction. With experience and improved technique and indications have evolved from lower incisor extraction, re-open space, back molar correction and more. Each technique has strengths and limitations we will review the information at present and especially the limits.

Dentofacial deformities are deviations from the normal relations between the various dento-maxillary segments and the facial skeleton. The study presents results of the various orthognathic surgical procedures used for 3 D correction of dentofacial discrepancies and asymmetry. It emphasizes the favorable outcome of the combined trreatment protocols and the importance of planning. Material and methods. The treatment protcol was age-related and included a first stage for diagnosis of the type and location of the deformity with various methods ranging from the classic to the modern ones (CBCT, axiography, virtual and real 3D planning). At this stage, the orthodontic treatment was performed in order to align the dental arches. It was followed by at least one surgical intervention for multiple bimaxillary osteotomies. Results. The discrepancy, the antero-posterior-, vertical,- or transverse excess or deficit were thus corrected after adequate repositioning of the dento-osseous fragments. The last stage comprised the orthodontic or prosthetic occlusal refining. Cases of dentofacial deformities and complex malformation syndromes as well as their treatment using guided callus distraction (3D „bone distraction”, with orthodontic and dentofacial orthopaedic stages alternatively) are presented. Conclusion. The modern, combined interdisciplinary treatment of dentofacial deformities is the only one offering optimum and stable morphologic and functional results in time.

It is also important to keep an individualized and good intercanine distance with a view to have good aesthetics. After the third molar, the maxillary permanent canine is the most frequently impacted tooth. The prevalence of impacted maxillary canines is about 2 per cent, more common in females than in males. The impaction of maxillary permanent canine is a frequently encountered clinical problem and often lead to time consuming and expensive orthodontic treatments. The most impacted maxillary canines are ectopically positioned, palatally or bucally to the dental arch. In European samples most impacted canines are palatally displaced. In about fifty per cent of the impacted maxillary canines they cause resorption on the adjacent incisor roots. It is essential that make an early diagnosis of impacted maxillary canines. At the age 9 – 11 years the position of the maxillary canines must be settled. In most cases by clinical supervision including digital palpation. In about 10 per cent of the children in these ages the clinical investigation must be supplemented with intraoral radiographic investigation. When suspicion to resorption on incisor roots the intraoral radiographs could be supplemented by computerized tomography (CT) investigation. Children with ectopic eruption of maxillary first permanent molars, diagnosed in 6-7 years of age, are considered risk patients for having impacted maxillary canines some years later. Enlarged dental follicles of the maxillary canines tell us that these canines are out of their normal position. Dr. KRISTER BJERKLIN is a well-known voice for the anomalies of eruption.

Similar to limb lengthening the evolution of craniofacial distraction was based on development and improvement of dento facial tractions, craniofacial osteotomies and skeletal fixation methods. Ilizarov described four stages: 1. Corticotomy or osteotomy 2. Latency period for primary callus organization 3. Gradual distraction 4. Retention or consolidation period – for callus maturation and mineralization In the lecture it will be presented our experience in: 1. Maxillary cleft deficiency using extraoral and intraoral distraction devices -Long-term results. 2. Mangement of Pediatric Obstructive sleep apnea by Distraction Osteogenesis 3. Treatment of facial asymmetries. The use of TAD (Temporary Ancorage Devices-Orthodontic Implants) to control the distraction vector will be also presented.

These model of diseases is nowadays clearly accepted by scientific groups all over the world. One of the clinical features of these diseases are migrations which may cause aesthetic complains from patients but can be solved by orthodontics. The aims of this clinical lecture is to show the following most important points, essential to be known for our daily practice: 1. The understanding of this infectious disease and its progression. 2. The importance to stabilized the disease before to start any orthodontic treatment. 3. Orthodontics is a precious partner for the periodontist but periodontics is also a precious partner for the orthodontits! 4. The importance of a very strict protocol in order to maximize the long-term clinical succes rate regarding these periodontal compromised patients. «long-term» clinical cases (up to more than 25 years follow-up) will illustrate this lecture. Dr Frédéric JOACHIM got his D.D.S. degree from the University of Lille (France) in 1984 and a M.Sc. degree in Periodontology at the Eastman Dental Hospital (University of London, U.K.) in 1989. Since 1989 he is working in Lille in private practice limited to periodontology and implant surgery. The main field and reputation of his practice is the treatment of severe periodontal diseases associated with orthodontic and / or implants therapies when needed. He is still active in clinical research. Dr JOACHIM has published several chapters in French and international books and also many papers in French and in English. He enjoys to share his experience with colleagues during lectures about these subjects, in France or in foreign countries. Fredric Joachim 49 Abstract Book MINI-IMPLANTS Alessandro Perini (Italy) Member of Italian Society of Periodontology, Italian Society of Oral Pathology One of the most profound innovations in the field of orthodontics has come with the use of mini screws. Some authors have previously tested other systems for bone anchorage but only with these devices they reached a simplicity of use and effectiveness that allow also an extensive clinical use. The miniscrew in fact allows a bone anchoring with the advantage of canceling (in some cases) the use of clasic dental braces and the need to use extraoral anchorage which is quite difficult for the patient. This system offers bigger comfort for the patient, greater efficacy and reduction of compliance required. From the clinical point of view, this means shorter treatment period with better final results and with the ability to perform extremely difficult movements once made with traditional techniques. In this presentation we will brieffly discuss the historical part, introduction and merchandise, studying all aspects in which the use of miniscrews is within the field of oral surgery, as well as the recovery of impacted third molars, impacted canines and the usage for orthodontic-surgical extraction, a technique performed generally for wisdom theeth in proximity to the inferior alveolar nerve.

Alterations of this function can lead to inferiority complexes, inadaptation and social isolation. Nowadays, the interest shown by the patients to this function has become significantly higher. Alterations of aesthetics can be perceived by the patient himself , if he arrived at the age at which he is preoccupied by personal appearance and can determine inferiority complexes or by the patients parents or entourage. Identifying and correcting these alterations exo- and endobuccal at an early age can lead to better therapeutically results from the physiognomic point of view than if they were to be performed at a later stage of development, sometime after the end of growth. AIM: The present study wishes to describe and identify the facial modifications of the appearance from frontal and lateral view on a group of patients that presented themselves at the Dental Pediatric Clinic from Cluj-Napoca between 2000 and 2010. The study consists in a descriptive part and a statistical one. MATERIAL AND METHODE The study was conducted on a group of 121 selected patients from a total of 167 with ages between 6 and 14 examined in the Dental Pediatric Clinic from Cluj-Napoca. The other 46 patients were excluded from the study because they did not meet the selection criteria. RESULTS AND DISCUSSIONS The study emphasized the difference of addressability between female and male patientsseeking dental treatment in favor of the female group and also a direct relation between the aging process and the perceived importance of the aesthetic appearance. CONCLUSIONS The perception of a less desirable personal appearance represents a reason of addressability for patients in Orthodontic services and starting a treatment at a proper age, during the development of the dento-maxilary system will have a beneficial impact on the improvement of facial appearance.

The purpose of this study was to evaluate the frequency of canine anomalies and the opportunity and possibilities of dental arch alignment of the canine with various anomalies. Material and methods. We performed a statistical study of the canine ectopia and impaction. The sample included a total of 627 patients aged 14-28 years. Both in the case of canine impaction and canine ectopia we took into consideration the maxillary or mandibular positioning of the canine, the oral or buccal positioning of the canine, the presence of unilateral or bilateral abnormalities. We used the following radiological investigation methods of the canine: orthopantomography, occlusal radiographs, lateral cephalometric and the CB-CT method. For exemplification we shall present several cases from my personal casuistry, including a case of canine transmigration. There will also be several borderline cases regarding therapeutic options for impacted canines. Results. The frequency of canine ectopia is very high, reaching values of 23.6%. The frequency of canine impaction that we came across was of 2.34%. The CB-CT method is the best option for the accurate diagnosis of impacted canines in terms of their root appearance and relations with neighbouring anatomical structures. Conclusions. Given the major role which the canine holds in the functionality of the stomatognathic system, it is necessary to address these anomalies with maximum responsibility in the current context, taking into consideration the fact that the possibilities for investigation and for orthodontic and surgical-orthodontic treatment are highly performant. Keywords: ectopic canine, impacted canine, orthodontic treatment. Dr. Ligia Vaida graduated in 1995 from University of Medicine and Pharmacy “Iuliu Hatieganu“, Cluj-Napoca, Romania.

The treatment of severe cases like dental intrusion needs a multidisciplinary approach but relies mostly on orthodontics. If, in the case of a non-complicated tooth fracture it is decided that the treatment of choice consists of adhesive reattachment, than the fragment must be kept moist until the procedure.

The occurrence of recessions was found to increase with age. Frequently interested are the mandibular central incisors, the maxillary canine ,the first premolar . The etiology of the gingival recessions is not completely elucidated and it is multi-factorial. Predisposing factors are necessary for the onset of the recession and are essentially anatomical. Initiating factors which, in a risk area, will promote the onset of the recession. Among the determining factors we will notice the periodontal inflammation caused by the bacterial biofilm (dental plaque), the patients with aggressive brushing (mechanical trauma), the intraoral piercing, the latrogenic factors. The key question would be: Is orthodontic movement of the teeth is one of the determining factor? Based on various clinical cases and on literature results , we display that the orthodontic treatment has periodontal limits, specific for each patient and that the orthodontist- periodontist should evaluate together the risk-benefit balance for each patient.

Material and method: The relapse during orthodontic treatment is the normal reaction of human body to reestablish the homeostasis existing before treatment. In most of cases the relapse expresses the loose of balance between form and function. There are many factors that contribute to relapse, such as:age, constitutional type, type of facial development, type of dental-facial anomaly, gravity of anomaly, the association of dysfunctional factors, the collaboration level as well as the result of active orthodontic treatment. During the preliminary stage of study it was considered a sample of 569 patients that had followed orthodontic treatment,with ages varying from 9 to 25 years old.Out of this sample, 501 patients followed a treatment with fixed orthodontic appliances while 68 were treated using mobile orthodontic appliances. At the end of the active orthodontic treatment, those patients were installed retainers of the following type:Hawleyplate, vacuum splint-capand retainers. The patients were then scheduled to attend checks during retaining period, at time frames varying from 6 to 12 weeks. The sample was monitored for relapse evaluation for 3 years. Results: Out of 501 patients with fixed orthodontic appliances, there were just 312 attending the checks during the relapse period. Out of the 312 patients, the relapse was observed to 107 of them, such as: 29% of the patients with retainers presented relapse, whilst 21% of the patients with vacuum splint-cap presented relapse and 32% of the patients with Hawley plate presented relapse as well. Conclusions: Due to the complexity of factors contributing to relapse occurrence, as seen during assessing the above mentioned sample no matter the retaining method in use, the relapse remains a subject incompletely understood and subject to a continuous debate. THE EPIDEMIOLOGY OF DENTO-MAXILLARY ANOMALIES AND THE IOTN INCIDENCE ON A SAMPLE OF CHILDREN AND YOUNG ADULTS FROM NORD-EAST OF MOLDAVIA AREA Sorana Rosu, Carina Balcos, Catalina Danila, Irina Zetu Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Iasi, Romania Purpose: assessment index of orthodontic treatment need (IOTN) and the benefits of it. MATERIALS AND METHODS: lot includes 650 subjects aged 6-29 years who have a wide range of orthodontic pathology. The diagnosis was based on clinical examination, radiological and study model. Giving IOTN scores was performed by examining the study models and photographs of pre-treatment of subjects assigned a score for each of the two components of the index AC and DHC. Results and Discussion: The study global treatment need to observe that the group needed treatment prevails aesthetically moderate, followed by a slight need and a clear need for treatment. Study global treatment need in terms of dental health, points out that the study group subjects must prevail high and very high. Conclusions. Application of IOTN index allows the identification and quantification of potential patients need treatment (in terms of aesthetics and dental health) in order to establish priority of orthodontic treatment. In the study group we identified a small number of subjects who had a low need for orthodontic treatment. THE VALUE OF THE SURGICALLY ASSISTED RAPID MAXILLARY EXPANSION Victor Costan, Irina Nicoleta Zetu Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Iasi, Romania The surgically assisted rapid maxillary expansion is a procedure with fast and predicable result. The surgical procedure is not a very traumatic one and it is recommended to the patients after finishing the period of growing. In our experience, the method is a reliable one and permits diminishing the treatment period, sometimes avoiding a new surgical procedure. 57 Abstract Book NOONAN SYNDROME: A CASE REPORT CLINICAL FEATURES AND TREATMENT GUIDELINES Raluca Maria Mocanu, Irina Nicoleta Zetu, Adriana Bălan Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Iasi, Romania Noonan syndrome is an autosomal dominant multisystem disorder. This syndrome is associated with cardiac anomalies and a distinctive facial appearance, characterized by genetic heterogeneity. Noonan syndrome affects both females and males, and has a estimated incidence of 1 per 1000- 2500 live births. The report aimed to present the cranio-dento-facial findings in a case of Noonan syndrome in a 6-year-old male. The patient presented a facial dysmorphism with bilateral telecanthus, hypertelorism, ptosis and a tendency for exophtalmos. The face shape was one of inverted triangle, with a relatively large nose and full lips. He had a tendency for lip incompetence and he reported the habit of mouth breathing. Oral examination revealed the primary dentition with extensive and multiple profound caries lesions , most of them with atypical locations and defects in teeth mineralization and dystrophies. The lower primary central incisors were exfoliated and the primary upper incisors had baby bottle tooth decay. The patient presented a narrow high-arched palate with prominent rugae. The presence of an important skeletal anterior open bite can be clinical correlated with the thrust tongue habit with abnormal swallowing pattern, although no nasal obstruction was found. The postlacteal plane was in mesial step. A multidisciplinary approach- pedodontic, orthodontic and endocrinologic treatment was planned. The patient’s growth and hormone level was closely monitorized by the endocrinologist. The patient received a myofunctional appliance, in order to correct the tongue thrust habit and to control the anterior skeletal open bite during the period of upper and lower incisors eruption. The frequency of control visit are at 2 months and the eruption needs to be supervised. MULTIDISCIPLINARY MANAGEMENT OF OLIGODONTIA Ştefania Dinu*, Alexandru Ogodescu*,Emilia Ogodescu*, Mălina Popa*, Cristian Dorin Dinu** * Department ofPaedodontics-Orthodontics, Facultyof Dental Medicine, University of Medicine and Pharmacy Timișoara, Romania ** Private Practice, Timişoara, Romania Aim: The purpose of this poster presentation is to describe the management of a case of nonsyndromicoligodontia and to present the clinical implications and the patient’s restorative treatment. Subjects and method:A 19 years old female patient was referred to the University Of Medicine and Pharmacy Timisoara, Faculty of Dental Medicine, for orthodontic treatment and replacement of missing teeth. The clinical and radiographic examinations, including cephalometric, orthopantomographic and intraoral radiographs, revealed that 9 permanent teeth were absent.The treatment plan included 2 phases, the orthodontic therapy and theprosthetic rehabilitation. Results: After 2 years of orthodontic treatment, reconsidering the quality of bone in the edentulous area, a conventional dentalbridgeswere preferred in this case. The conventional bridges have been used to provide a fixed option in this severe case where adhesivebridges were impractical and implant treatment would involve grafting, which the patient wishes to avoid. The final prosthetic rehabilitation was performed with porcelain fused to metal crowns, which provided a satisfactory functional and aesthetic result. Conclusions: Treatment in the present case includes multidisciplinary management to improve not only speech, aesthetic and masticatory function, but also has major psychological implications. It is very important to make clinical and radiographic examination to every patient with retained primary teeth for early diagnosis and intervention to improve oral health and to avoid psychological distress. HYPODONTIA OF 6 PREMOLARS: CASE REPORT Cernei Eduard Radu, Irina Zetu Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Iasi, Romania Congenital missing teeth are a common anomaly in the craniofacial skeleton. The agenesis of the 4 maxillary premolars and mandibular second premolars is uncommon in orthodontic patients. Therefore we want to report a case of a patient aged 20 years who presented for aesthetic and functional disorders in the Clinic of Orthodontics and dento-facial orthopedics in Iasi. On extraoral examination facial changes occur not relevant. Clinical examination reveals Class III Angle molar malocclusion, frontal open bite, the presence of temporary canines on the upper arch, mesial inclination of the lower permanent molars, enamel damage of the upper central incisors. OPT examination and anamnesis diagnosed agenesis of upper premolars and lower second premolars. The lateral cephalometric indicates a slight skeletal Class II (∠ ANB inv. = 3.040). 58 Abstract Book TREATMENT OF CLASS II DIVISION 1 MALOCCLUSION WITH MYOFUNCTIONAL TRAINER SYSTEM IN GROWING PATIENT Ștefania Dinu, Alexandru Ogodescu, Lazea Andreea, Cristina Lazăr, Luca Magda Department of Paedodontics-Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Timișoara, Romania Aim:Aim of this report is to describe the results of the two-stage myofunctional treatment of a patient in mixed dentition with class II malocclussion division 1, deep bite, increased overjet and gummy smile, hyperactive mentalis muscle on swallowing. Subjects and method: A 9-year-old girl patient reported in good health with chiefcomplaint of protrusion of upper frontal teeth and unpleasant looks. In this clinical situation the objectives of our treatment were to reduce the skeletal class II pattern,control bicuspids and canines eruption, establish correct overbite and overjet, improve gummy smile and the lip incompetency. The myofunctional treatment included the use of Interceptive Class II Appliance i-2™ (Myofunctional Research Co.) without core in the first stage and with core in the final stage. The active treatment time was 20 months, using the elastodontic appliances every day for 2 hours and overnight. Results: At the end of the active treatment, the patient had normal overjet and overbite, fully competent lips, lip trap completely eliminated and straight facial profile. The correction of skeletal class II malocclusion was obtained in 20 months just using Interceptive Class II Appliance i-2™ at the right time of eruption of permanent teeth. Conclusions: The treatment of skeletal class II division 1 depends upon the growth potential, age of the patient, severity of malocclusion, and, the most important, patient’s collaboration. This case demonstrates that the myofunctional appliances induces dentoalveolar changes with a significant reduction of overjet and can be successfully used with appropriate patient selection, during growth phase. THE INFLUENCE OF CARIOUS LESIONS FROM TEMPORARY MOLARS ON THE CARIOUS RATE OF THE FIRST PERMANENT MOLARS Laura- Maria Gavrila, Marinela Pasareanu, Dana Cristiana Maxim, Vasilica Toma Department of Paedodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Iasi, Romania Summary. The aim of the study is to evaluate the influence of the temporary molars odonto-periodontal status on the carious rate of the first permanent molars. Material and methods: The study lot consisted of 212 subjects (104 girls and 108 boys) aged between 6 and 12 years, from both urban and rural areas of Iasi county. Results: On the maxillary, the first permanent molars (1.6, 2.6) submitted simple caries at a rate of 11,32% and black spots in 24,52% of the cases, being associated with the presence of simple caries in first temporary molars (5.4, 6.4) at a rate of 23,07%, respectively 27,65%, and on the second temporary molars (5.5, 6.5) at a rate of 40%, respectively 40,42%. On the mandible, the first permanent molars (3.6, 4.6) submitted simple carious lesions at a rate of 20,75%, respectively 18,86%, and black spots at a rate of 22,64%, respectively 26,41, being associated with simple carious lesions on the first temporary molars (7.4, 8.4) at a rate of 30,23%, respectively 27,27%, and on the second temporary molars (7.5, 8.5) at a rate of 40%, respectively 34,04%. Disscution: In our study, similar statistical data have been obtained to those from the study accomplished by I. Mejàrea et al. (2001) in which they concluded that the carious rate of the first permanent molar depends on the status of the second temporary molar, and, from the study undertaken by Skeie, MS et al. (2006), which raported the fact that carious experience on the second temporary molars is the best predictor of carious risc on the first permanent molars. Conclusions: The carious rate of the first permanent molars depends on the temporary molars odontoperiodontal status. The first permanent mandibulary molars have been affected more than the maxillary ones, while the temporary molars, both mandibulary and maxillary, have been almost equally affected by the simple caries. 59 Abstract Book THE PAPILLA PRESENCE INDEX (PPI) DURING THE INTERDISCIPLINARY ORTHODONTIC TREATMENT OF ADULT PATIENTS Alexandru Ogodescu, Magda Luca, Emilia Ogodescu, Ștefania Dinu, Mălina Popa 2nd Department, Discipline of Paedodontics-Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Timișoara, Romania Aim of investigation: The presence or absence of the interdental papilla during the orthodontic treatment of adults is a topic of great concern since it involves great esthetic and functional problems. The purpose of this clinical trial is to highlight the incidence of these unsightly areas on a group of adult patients who have undergone orthodontic treatment and to evaluate their evolution with the Papilla Presence Index (P.P.I.) proposed by Cardaropoli and coworkers. Subjects and methods: The trial included a group of 21 adult patients of both sexes, with ages between 22 and 57, whose photos, radiographs and dental study models were analyzed at the beginning of the orthodontic therapy, after completion of the alignment and leveling stage and at the end of the treatment. The assessment included the aspect of the gingival embrasure following the alignment of the teeth, local periodontal evaluation and the use of P.P.I. The patients were treated by dental stripping followed by orthodontic space closure of the spaces, periodontal microsurgery, prosthetic veneers or a combination of the three. Results: All examined patients presented “black triangles” with a maximum at the end of the alignment and leveling stage when a P.P.I. score of 3 or 4 was present in 57% of the cases. At the end of the treatment P.P.I. scores of 3 or 4 were present in only 24% of the cases. Conclusions: “Black triangles” represent an important issue in the orthodontic treatment of adults and it should be considered at the start of the treatment. By anticipating the evolution and applying a proper interdisciplinary cooperation protocol we can obtain optimal results for both physician and especially for the patients. RECONSTRUCTION OF THE INTERDENTAL PAPILLA USING AN INTERDISCIPLINARY ORTHODONTIC AND PERIODONTAL APPROACH Alexandru Ogodescu*, Ștefania Dinu*, Emilia Ogodescu*, Magda Luca*, Ștefan Stratul** Department of Paedodontics-Orthodontics, Faculty of Dental, University of Medicine and Pharmacy Timișoara, Romania Department of Periodontology, Faculty of Dental, University of Medicine and Pharmacy Timișoara, Romania Aim of investigation: Frequently during the orthodontic treatment of adults the “pink” aesthetic becomes a problem due to loss or absence of interdental papilla. This clinical situation known as “black triangles” is unacceptable to the patient since it involves both esthetic and phonetic problems. The purpose of this case report is to describe a new protocol of papilla reconstruction with an interdisciplinary orthodontic and periodontal approach. Subjects and methods: To improve the appearance of the esthetic zone of a 22 year old girl a combined periodontal surgery and orthodontic technique were used. The surgical periodontal technique consisted of placing a connective tissue graft into the pouch created at the base of the papilla. The gingival embrasure was reduced by stripping followed by orthodontic space closure. Results: This combined orthodontic and periodontal surgical technique lead to an enhancement of the height of the papilla, an improvement of the papilla presence index (PPI) and a proper esthetics. Conclusions: This case report reveals a new therapeutic possibility for the reconstruction of the interdental papilla and emphasizes the importance of interdisciplinary collaboration. CHANGES IN PERIODONTAL-PATHOGENIC MICROBIAL FLORA DURING THE FIXED ORTHODONTIC TREATMENT Liviu Zetu, Ionut Aevoae, Alina Adronovici, Mugur Cojocaru Department of Periodontology, Faculty of Dental Medicine, University of Medicine and Pharmacy Iasi, Romania Specialized studies demonstrate some unfavorable influences that orthodontic treatment can have sometimes on periodontal tissues. This study analyzes in real time through PCR which are the modifications of periodonto-pathogenetic microbiological flora at 6 months from the beginning of the orthodontic treatment 60 Abstract Book ORAL HABITS IN CHILDREN - A PREVALENCE STUDY Iulia M. Ştefănescu, O. Stefanescu, Irina Zetu Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Iasi, Romania BACKGROUND: The influence of oral habits on dental and facial development and on malocclusion prevalence is still a subject of great interest in the literature. The impact of oral habits on dental and facial development has been well documented over the past 100 years, although there are still many that ignore this fact. AIM: to determine the prevalence of oral habits among children in primary school, according to sex. MATERIALS AND METHOD: This sample had 416 children aged 6-11 years old. The children were selected from urban and rural public schools of Bacau and Iasi, Romania. The sample included 211 boys and 205 girls. The prevalence of a habit was recorded by interview, clinical and paraclinical examination. Sex differences were calculated by using Fisher's exact test to evaluate statistical significance for oral habits between male and female children. This report is a part of a larger study on oral habits and its impact on oral development. RESULTS: showed that the prevalence of oral habits was of 27,5%. The prevalence of oral habits derived from this sample is representative for the school population in Romania in the age group of 6-11 years. Mouth breathing was the common habit (19,1%) followed by tongue thrusting (6,3%) and tongue sucking(2,1%) Tongue thrusting was common in girls when compared to boys. CONCLUSIONS: There were no significant differences between boys and girls regarding the prevalence of oral habits . For the specific habit types there was a sex difference. Mouth breathing was the common habit for both sexes and tongue thrusting was common in girls. Key words: tongue thrusting, mouth breathing, oral habit SMILE AND THE ORTHODONTIC TREATMENT Bogdan Dragomir, Irina Zetu Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Iasi, Romania In recent years, increasingly more patients are addressed and the orthodontist to correct the appearance of facial aesthetics, that would allow a better integration in life, especially in your relational life. In this context Smiles quality assessment appears as a primary document in your assessment of a final result of orthodontic treatment. May we trust in numbers, angles or their intuition, aesthetic appreciation in orthodontics and maxillofacial assessment dismorfozelor repercussions is examining patient's face and profile either radiographic or photographic or optical. To be convinced of this fact, it is enough to revise the definitions of "aesthetic facial lines." Note that we are "forced" to look at each patient through the eye engraver ancient Egypt, though the image to judge whether our treatments have achieved the aesthetic plan, the most important goal: improving Smiles. This becomes even more important today in the century photography, cinematography and television we propose a "publicity smile" with perfectly aligned teeth, white, bright smile evolved into a labial labial dental smile which, though pleasant to the sight, seems often artificial, devoid of personality. But the media, increasingly more present in everyday life, understanding the importance of this expression and exploiting it to the maximum contributed to the emergence of a true "investment" to create a standard image for individual feel good, so good . An asymmetric smile that reveals cavities or crowded incisors, an edematous gingiva or absence of one or more teeth will create person looks at him, as a person who would look at herself in a mirror, a sense of pain and not pleasure . In this socio-economic context orthodontist has the responsibility to rebuild "facial image" pleasant, so treatment to address not only therapeutic but also aesthetic. But we question whether we need to align "Smiles teeth" according to your personality or it is required to follow the rules and canons of beauty of our age. The risk of patients depersonalize us? We don’t aim to answer this question but just want to raise awareness on the importance of medical colleges Smiles and we propose elements of study and reflection, featuring series of clinical cases of patients with malocclusions in different specialties of physicians found that, and the results that we can obtain through our orthodontic treatments. 61 Abstract Book ASSESSMENT OF VERTICAL FACIAL SYMMETRY OF A GROUP OF STUDENTS Georgiana Macovei, Buturca Diana-Alexandra, Monica Mihela Scutariu, Dragos Fratila, Irina Zetu Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Iasi, Romania Symmetry, in particular the facial symmetry is often perceived as the same concept as beauty. Anthropometry is the science which involves determining the human measurements and proportions, based on race, sex or age. From ancient times the aesthetic concept was used which established the harmonious human physical proportions. A series of anthropometric measurements are used in orthodontics and dentistry in order to assess the vertical facial symmetry of our patients. The aim of the study: Assessment of vertical facial symmetry to a number of students of both sexes in order to evaluate the differences that can be distinguished by gender and individual characteristics. Material and method: The study group was represented by a total of 30 students, 15 female and 15 male. To measure vertical symmetry we used the following methods: Leonardo Da Vinci, Leonardo Da Vinci modified, Boianov and Boianov modified. Data processing was performed using Microsoft Office Excel 2010. Results and conclusions: After processing the data obtained by the methods mentioned, we found significant differences between the results obtained from the study group. Vertical dimension of the lower and middle facial height varies by gender and the characters of the individuals studied. Key words: the face symmetry, anthropometric measurements, aesthetics. THERAPEUTIC CLASS II- POST-ORTHODONTIC TREATMENT CASE REPORT Ionescu –Lungu Andreea, Ene Elena, Marinescu Radu, Zetu Irina Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Iasi, Romania In some cases of skeletal and dental class II malocclusion, a compromise therapeutic option is single maxillary extraction, getting in the final a “therapeutic “ occlusion. For patients who can recover the skeletal discrepancy by mandibular growth only by surgical option, teenagers with a unfavorable growth scheme and as well as in some adults cases, we can use this pseudo-surgical solution. In this context we will present a clinical case from a patient with a class II hypodivergent dental-maxillary disharmony, at which we extracted 2 premolars only at the maxillary. With the help of a bonded orthodontic appliance Roth prescription slot size 0,022-0,028 inch, we compensated the skeletal disharmony by bringing back the incisor-canine group until the contact with lower arch. By applying a particular treatment protocol, in the end we got a satisfactory functional and aesthetic result, with a molar class II relation mentained. BIMAXILLARYOSTEODISTRACTION AN ALTERNATIVE NONEXTRACTIONAL SOLUTION FOR THE MANAGEMENT OF CLASS ONE MALOCCLUSIONWITH CROWDING. D. Angelescu, M. Baciut, S. Bran, M. Mesaros Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy Cluj-Napoca, Romania Class one malocclusion with crowding represents more than a half from the total dento-maxillary anomalies. The management of this malocclusion implies either an extractional or annonextractional approach. Mandibulo-maxillary ostodistraction represents a nonextractionalalternative for class one anomalies with crowding and maxillaries transversal deficiencies. This case report describe the surgical-orthodontic approach of this kind of malocclusion. To accomplish the treatment objectives that were established at the beginning of treatment, two different osteodistractors were used: one tooth borne on the maxilla and the other bone borne on the mandible. The space gain by this procedure was enough to accomplish a good result. This fact proves that mandibulo-maxillary osteodistraction is a viable alternative for the management of this malocclusion . 62 Social Programme Thusday, JUNE, 06th 2013 OPENING CEREMONY Time:19.30h Venue: The Congress and Exhibition Palace in Congress Hall Palas Iasi (Vivaldi Rooms) Dress Code: Business casual ARTISTIC PROGRAMME The band “Stars of Music” Iasi Instructor prof.
