Due to different market requirements the European, American and Asiatic distribution operations are being consequently developed at a local level. Renfert Brazil was therefore recently established – for even more service on location and shortened delivery times because of the availability of goods. Genuine solutions with added value To ensure the wishes of dental technicians are optimally implemented the Design and Development Department is being continuously extended – with the focus on genuine solutions suitable for daily use and efficiency. The benefits of every detail, however small, are continuously scrutinized, refined and improved. For the IDS 2015, for example, the SILENT extractors will be supplemented (SILENT compactCAM for extraction of the CAM unit) and the Basic microblasters will also receive a new highperformance family member with the Basic eco. Renfert products therefore offer dental technicians intelligent solutions with added value – whether because of easy handling, easy assembly and maintenance, increased reliability or reduced costs. The declared aim of Renfert is not short-term success but the overall concept, which extends well beyond the point of purchase and which never leaves the dental technician stranded without support – for over 90 years and with certainty also in the future. » 2005 2011 2012 2014 2015 Market launch of the SILENT extractors and Twister vacuum mixers Market launch of the Trimmer MT3/ MT3 pro Sören Hug joins the company as the designated successor Competence extension by the multi-workstation extractor SILENT V4 90 years and the success story continues 5 RENFERT PRESENTS … www.renfert.com Internet & Social Media at Renfert Dental technology goes #Social In January 2015 we launched our social media strategy at Renfert.

Silent V4, for example enables individually adjustable suction power, adapted to the particular requirement. The unit is quiet “times four” and can be operated for up to four users simultaneously – for maximum health protection with minimum maintenance costs and space requirements.” Not only the employees of Dentcare Dental Lab were enriched by many impressions at the end of the successful event, Jeannette Giesche was also satisfied: “Service and good advice are the parameters that Renfert focuses on in cooperation with specialist dealers for the benefit of dental technicians. We not only want to develop and supply good products but provide the user with deep knowledge about the quality factors of the products and thus ensure increased process reliability and cost-effectiveness in the laboratory – to make longterm, satisfied and enthusiastic Renfert fans of users.” 11 PRODUCT WORLD www.renfert.com Quality and high-tech supports all-ceramic precision and esthetics The fabrication of all-ceramic restorations with an esthetic and precise demand requires high-quality materials and instruments for the fabrication process.
