1. Crown & Bridge design
Shaping tools
Transforms
When interacting with anatomies using the Transforms or Clinical handles Edition , the deformation mode was
improved to allow soother contours. When they are stretched , the continuity of the anatomical feature now prevails
over their integrity. Consequently, ungracious edges and grooves appearing when editing anatomies are now
eliminated.
Figure 1-1: When the handles are pulled, a
discontinuity is created around the
anatomical features.
Figure 1- 2: But when the handle is
released, an automatic smoothing is
applied .
The results are morphological shapes, adapted to their environment, with less design operations needed.
Chapter: 1
Clinical handles
The Clinical handles tool is the shaping tool that lets you manipulate the anatomical features individually. As you
select it from the right-click menu of a prosthesis, colored handles will appear on the tooth so that you can apply a
controlled deformation to the anatomy. You can control the surface deformation according to 2 modes.
NEW: Global
When you activate the Global deformation, moving a handle impacts the surrounding handles: they will move so
that the general anatomy is preserved. This mode is best suited for subtle or overall changes to the anatomy.
When editing with the Global mode, you can not add a handle by clicking on the anatomy. The amount of
handles is locked. With the Local mode, you can add as many as needed to control the deformation.
Local
With the Local transformation, the surface deformation is delimited by the handles around: only the surface
included inside the perimeter, formed by the handles, will be allowed to change. This mode can be used to apply
drastic or local anatomy deformation.
Figure 1-3: Initial shape
Figure 1- 4: Global deformation affects
other handles around the one you are
moving
Figure 1-5: Local deformation offers more
handles but only one can be displaced at
a time
Chapter: 1
Contact points
The Adjust contact point function is now completely automated. You do not need to previously define mesial and
distal contact points anymore in order to use the automatic adjustment. This function can be used on an automatic
proposition or on a crown on which you have used the shaping tools.
1. Right-click on a crown
2. Select Overlay (or Anatomy) > Adjust contact points
3. The dialog window opens where you can change the diastema value if needed.
4. Just click on Adjust contact points button and you’re done.
Figure 1-6: Right-click on
an automatic proposition
Figure 1-7: Contact is made in one click
Anatomy and Overlay cervical line synchronization
For this to happen, you must activate the option in User
Preferences > User Preferences . Then when you modify
one of them, the second is automatically updated to follow
the new line.
Chapter: 1
Adaptation environment
This step lets you identify a subset of dental points on the sur r ounding teeth, so that the CAD Engine is able to
analyze the context fr om the pr ovided infor mation. This is par t of the str ategy to impr ove automatic pr osthesis
pr opositions.
In order to use the improvements featured in this version, you must access the adaptation environment in the CAD
station by right- clicking on a prosthesis and choosing Anatomy (or Overlay in the case of a full crown) >
Adaptation Environment.
Define equator points:
1. Click on the Equator points icon.
2. Click on the equator of the teeth that surround the prosthesis.
Define points on the antagonist
1. Turn off model visibility
2. Select an anatomical feature from editor window
3. Click on the antagonist to place points.
4. Further occlusion adjustments will take this information into consideration.
Remember that you can also modify all the points that you have defined during the scan session in this
interface. When you do so, click the
button
to refresh the design.

Egg shell
Egg shell temporaries can be created from the scan of a natural tooth
prior to its trimming. In the CAD station, the Recompute function
offers the option of computing a virtual preparation. This computes a
generic, geometric shape that will simulate a preparation. Now, with
the egg shell feature, you can compute a virtual preparation that is an
offset of the contour anatomy. The milled temporary restoration will
have constant material thickness.

Chapter: 1
Tool compensation
A new parameter was added to material management to enable tool compensation 1 on overlays.
Material Management < Manufacturing Parameters
1. When this box is checked, it means that the tool compensation is calculated by the CAD Engine.
2. The tool radius for the outer and the inner surfaces are independent and can be of different sizes.
3. When the distance is set to -1 the compensation can be applied anywhere on the restoration. When another
value is set, the compensation can be applied only to this distance from the margin line.
ex: if the Compensation distance is set to 2 (mm), only the first 2 mm above the margin line can be
modified by the tool compensation function. Above that 2 (mm), the occlusal surfaces will remain
untouched.
1Tool compensation is a function that verifies that the shapes of the restoration can be milled with a milling tools that has the specified radius. If not, it will modify the
surfaces to ensure that all shapes that you see can be milled with the required level of accuracy. The result of tool compensation are displayed upon recompute of the
prosthesis.
Chapter: 2
2. Custom Abutments
Custom gingiva former
Also known as healing cap or healing abutment, a gingiva former is the device installed on the implant during the
healing phase to prepare soft tissues for the final restoration. With the DWOS Custom gingiva former, you can
create a subgingival profile without the constraints of generic stock abutments. This is most likely done on a
preoperative model scan on which the implants are positioned, as a part of the treatment planning. With the
integration of coDiagnostiX to DWOS, this is done seamlessly by importing a .xorder.
Moreover, the Custom gingiva former design can easily be converted into a custom abutment: the radical
area stays exactly the same, while the design can be customized above the cervical line. Both healing
and final abutments can be generated from the same order, thus ensuring perfect correlation.
Figure 2-1: Gingiva former designed on an
implant planning
Figure 2- 2: Once recomputed into a
custom abutment, the radical area
preserves the same shape to fit perfectly
the healed tissues.
Figure 2-3: Section view: the design that
was done on the gingiva former is
preserved on the radical part of the custom
abutment
Workflow example to design a custom gingiva former:
1. Open Order Management
2. Import a .xorder of an implant treatment planning
l
Your Implant kit library must include the implant that was chosen for the case (implant kits are imported in
the .ipflib format)
3. In the Scan Import station:
l
Drag this order
l
Click Yes to adjust vertical axis
l
Rotate the view to obtain an occlusal view and click OK
l
Position the arch on the model
Chapter: 2
l
Using the mouse, freely draw a line on the gingiva. It will define the abutment margin. It can be reworked
later in the CAD station.
l
Define an insertion axis for the abutment by rotating the view and clicking
l
Repeat margin and axis definition for every implant location
l
Exit
4. Process in the CAD Engine
5. In CAD:
l
A custom abutment is automatically calculated
l
Right-click on it and select Recompute
l
In the Prosthesis Type tab, select Custom gingiva former
l
You can use all shaping tools to form the healing device according the case's needs.
Gingiva former parameters
The automatic proposition of the gingiva former is computed from a set of parameters that you can access through:
Material Management > Custom Abutment Parameters
and
CAD station > Recompute
Chapter: 2
Improvement on design workflow and performances
A series of improvements on the custom abutment prosthesis makes it easier
and faster to design implant born restorations. Notably the automatic display
of the angle difference between the insertion axis and the custom abutment
axis was added.

3. Model Builder
Saw cut model
The DWOS Model builder allows to design a virtual model that, once printed, will fit perfectly with the plate system
of Baumann Dental® or with the dentobase system of Dentona®.
To realize such a model, you would simply choose the base plate on which you will mount your model and the
software will compute the required shapes for it to fit on the plate. And to allow removing the dies, you would use
the recently added Saw cut plane function, to create detachable sections. This imitates the hand-crafted models
that are cut with a saw afterwards. The benefits of the virtual method is that you can design the cut lines to your
will, curved or angled, without the real tool constraints of the saw. The 3D manufacturing method are limitless
regarding the shape of the dies that you want to extract.
Figure 3-1: Saw cut model on Baumann
plate
Figure 3-2: Model on Dentona plate
To create a Baumann or Dentona model:
1. Create an order.
2. Scan the impression.
3. Define margin and design parameters. Route forward.
4. Drag and drop the order in the Model Builder station.
5. Stumps parameters: Select Saw cut
6. Model production type: Select Default,
7. Articulator: Select your plate type betweenBaumann, EOS Baumann, Dentona big or Dentona small.
Once the model is computed, it is not necessarily well positioned according to the plate. To align them:
8. Right-click on the plate.
9. Select Edit Articulator.
l
Click and drag the plate to position around the model
Chapter: 3
l
l
Click and drag the green dot to freely move the plate
Click and drag the yellow dot to rotate the plate around the green dot
Make sure you click directly on the dots, and not through the model
Cut lines
Once the model is built, you can define as many cut lines as needed. To do so, right-click on the model and select
Set/Edit saw cut planes.
Saw cut planes
To create and edit Saw cut planes:
1. Right-click on the model.
2. Select Set/Edit Saw cut planes.
3. The editor window opens.
4. Click anywhere on the model to place a cut plane.
5. Edit the cut plane with the Spline mode 1:
l
Move it with the central blue dot.
l
Rotate it with the blue dot on its edge.
l
Use the green dots to curve it.
6. Or with the Axis mode : the path that you have defined with the Spline mode can
traverse the model with a custom angle.
l
l
Click on the green button at the arrow tail.
Move the axis to rotate the cut plane.The rotation plane is defined by the view. So if you want the cut
plane to rotate on a different direction, change your view point (by holding down the right-click) and try
rotating again.
7. The saw cut width corresponds to the gap that will be left between the model sections.
8. The connectors are shafts that will join the sections to facilitate the printing process. Add them by selecting
the Enable connectors checkbox. One connector will be added between each section. They can easily be
removed from the model after manufacturing.
9. Use the Connector radius field to define their radius.
1With the Spline mode you set the trajectory from a top view. And yes, you can draw splines! When doing a traditional saw cut model, the cuts have to be straight lines. But
with the model builder, we are simulating saw cuts: the dies are not cut with a saw but 3D printed with a digital process. Therefore what are referred to as "cut lines" can be
of any shape, even curved and angled.
Chapter: 3
Zimo model
Figure 3-1: Default model with Zimo
articulator
Figure 3- 2: Full arch default model with
Zimo articulator shown with the actual
articulator
This new model type is implemented for business partners of
The Dental Solution Inc. The Zimo model
computes a base with an extension that will snap onto the articulator used in its facilities.
1. Create an order and scan the impression.
2. Define margin and design parameters. Route forward.
4. Stumps parameters: Select Zimo Pin shape

to modify it if the result needs adjustments.
5. Model production type: Select Zimo and leave default parameters
6. Articulator: Choose between Zimo Half plate or Zimo Full plate, depending on the impression scan.
Chapter: 3
Mono block model
Figure 3-1: Mono block model with default articulator
Monolithic models have the particularity of having a fix preparation. Instead of having a removable stump on a pin,
the model comes in one solid block. A replica of the stumps is manufactured on the side, on its own base. Use this
stump type with any type of model.
To create a mono block model:
2. Stumps parameters: Select Mono block
3. Model production type: Select Default, Offset or Hollow.
4. Articulator: Select Back
The Front part will have to be added with the Add articulator function, found in the right-click menu on the
computed model.
New linear workflow
Once you drop the case in Model Builder, you will be asked to set parameters before anything is computed. By
clicking Next in a Wizard manner you'll be directed from one parameter window to the other:
1. Material
2. Pin shape (or die type)
3. Model type
4. Articulator type
Then at the end, when you click Finish , the model is computed.
If you want to change anything from the model, you can right-click on the element to modify it and use the
Recompute function. The toolbar on the right side is also there to let you rework the model as needed.
Chapter: 3
Stabilization bar
Model Builder > Right-click on model > Add Stabilization bar
Add a stabilization bar to facilitate the manufacturing of long span models. It helps reinforcing the model to
minimize risks of torsion or, eventually, breakage. The option window lets you customize the shape, width and
height of it.
1. Set the width and height dimensions
2. Select a bar profile from the drop-down menu
3. Click on the model where you want to place one end of the bar
4. Click where you want to place the other end of the bar
5. Move the dots to fine-tune the positioning
6. Click

4. Bars
Custom Profile Editor
Figure 4-1: Bar designed with a custom
profile
The Custom Bar Profile Editor is presented as a new dedicated library where you can manage your own bar profile
designs. It was integrated for creating custom wrap-around and hybrid bars. You can save the profiles that you
create, export and import them. The library also contains 4 default profiles to help you get started.
Default profiles
The bar profile editor now comes with three basic profiles for fixed prostheses:
l
Cross
l
Lambda
l
Trapezoid
And one advanced profile that was developed for hybrid restorations.
l
Staircase retention
These profiles are locked in the Bar profile editor , but here is what you can do
with them:
1. Right-click on a default profile and select Duplicate . You would then be able to re-dimension the profile, but
the general shape is preserved. You can Save it as a custom profile.
2. When you apply one of those profiles to a bar, it can be scaled in the same manner, but again, the general
shape is preserved.
Chapter: 4
Custom profiles
The profiles that appear in green, such as the "custom" profile, are fully editable. When you use them on a bar
design, you can move the dots that make up the shape, to deform the bar. You can create as many profiles as
needed. You can also export/import them.
1. In the bar profile editor, right-click on the Bar Profile folder and select
2. Name your profile
3. On the square profile that is created: Click and drag to move a dot. Click on the line where you want to add a
dot. Click on a dot to delete.
4. Right-click on a dot to convert a corner into a spline or circular trigger. Then select Manually edit tangents
in order to move those triggers.
5. Activate the Display grid for your reference. Adjust the distance (mm) between each line with the Grid
Resolution field.
6. When you activate Snap to grid the points can only be placed over intersections on the grid, preventing
arbitrary measurements. Disable to freely move the dots.
7. Save you custom profile and it will be available in the Bar editor of the CAD station.
Setting > Bar Profile Editor

Chapter: 4
To manage profiles
With a right-click on the Bar Profile folder, you can export your profile library into a
new format .bpflib for other DWOS users. You can also load profiles created by
other DWOS users by importing them in the .bpf format or their entire library from a
.bpflib format.
When you import a profile or library and you are not able to see the new
items, try closing the Bar Profile Editor and reopening it.

Bars from custom profiles
The new bar engine lets you modify the bars you create from custom profiles by tweaking their profile locally, in
their context.
1. In the CAD station, drop an implant bar case that was properly scanned with the implants, gingiva, and wax up
(optional)
Chapter: 4
2. The automatic proposition is computed. Right-click on the bar and select Edit implant bar
3. In the Bar design mode (first tab), select a Planar constraint, define the global axis and enter a gingiva
spacer value.
4. In the advanced section, select a profile between: wrap around (basic), hybrid (advanced), or custom.
Take note that the editing of bars made from Basic (Lambda, Cross, Trapezoid) or Advanced (Staircase) will
be limited to keep the shape' s integrity. Bars from Custom profiles can be shaped freely
5. With the green dots, you can adjust the bar height and path. Click on the path to add more dots (yellow) and
refine the adjustments.
6. Now when you switch to the Segment design mode , the bar can be deformed with the purple lines. The
Deformation size cursor (see fig. 7 on page 27) is what make the difference between pulling the entire line or
just a segment of the line to create a local deformation.

Staircase bar
The bar created with the Staircase retention profile has the particularity of having a protected upper section, in
addition to a lower section that will be adapted to the gingiva. This combination of different areas make this bar
perfectly adapted to hybrid usage: the bottom part is exposed, while the upper is wrapped.
Chapter: 4
Cutouts
A new tool was added to design cutouts crosswise through bars built from your custom profiles (and also from the
Staircase retention profile). Access the cutout tool from the Attachment tab of the Bar options editor. With the
given cutout parameters you can create a wide variety of cutout shapes.

Attachments and spacers
Bar attachments as well as spacers can be added on Milled bars. The spacer blocks are handled by DWOS in the
same manner as attachments; they are managed in the Attachment library.
You can access your implant bar library while using the bar editor by activating the Attachment mode.
To add attachments to an implant bar:
1. In the CAD station, right-click on a bar and select Edit implant bar
2. Set the bar or bar segment as Milled bar
3. Finish the bar editing before adding attachments (the attachments are always removed when you edit the bar
or any bar segment)
4. Select the Attachment mode
5. The Attachment kits drop-down menu
will display all attachments from your library that are suitable for
implant bars. Select the one you wish to add.
6. Click on the bar where you want to place the attachment.

7. You can move it afterwards with a left-click and drag. As for the spacers, use the yellow handle to rotate them.
8. You can delete it with a left-click.
When you add a ball attachment, you will see it displayed on the bar. But when you exit the CAD station and
the design is being merged, what will really be computed is the appropriate hole in which the attachment will be
inserted.
If the bar profile is too narrow or thin to accommodate the hole, you can see what happens by reading the
section: Attachment hole compensation.

Improved Initial Proposal
For milled bars
Before doing any editing, you will notice that the segments look more natural. Instead of straight segments joining
the pillars, you will see smooth curves skimming the gingiva. That is because the milled bar path is computed
according to the clinical arch that was defined in the scan station.
For optimizing the initial proposal of milled bars you should take good care of the arch's path. To optimize, consider
the following:
l
l
l
The centre dot should be placed between the
anteriors
Both dots on the edges should be placed beyond the
last molar
Then, to flatten or accentuate the arch's curve, click
and hold the dot at the tip of the line while scrolling
with the mouse wheel.
You will reduce customizing time in the design step if you
already have the bars in mind.

Merging
Attachment hole compensation
When you add an attachment to a bar, the hole in which the attachment will be inserted, is computed upon merging.
Knowing that milled bars have a minimum thickness requirement, it can happen that there is not enough material
around the hole to support the milling process. The software would then automatically add the necessary thickness
all around the holes based on the minimum thickness that is set in the Material Management. This is what is called
"hole compensation".

merging
Figure 4-1: When quitting the CAD station,
merging is mandatory for bar designs: it is
selected and grayed out
Chapter: 4
Figure 4- 3: This is where to set the
minimum thickness which determines if the
design needs compensation.
More Organic Shapes
Our implant bar design tools already included adding attachments and spacer blocks from a library, automatic
material compensation around (attachment) holes, and gingiva offset setting. They are now enhanced with rounding
radius setting for milled bars, and automatic rounding of the junction between pillars and segments. All of these
make your design production-ready in less time.

implant.
As you create a new order, the Wizard will take you from one step to another by clicking theNext button.
1. Order definition
2. Scan session configuration
3. Scanning the model alone
4. Implant scan contour definition
5. Scanning the model with the scan jig on the implant
6. 3-point repositioning of the implant on the model
7. Gingiva scan contour definition
8. Scanning the model with the gingiva
9. Cervical line design
10. Insertion axis
11. Adaptation reference points
12. Design environment
The design environment will display an automatic proposition that you can edit with the full suite of shaping tools.

Partial Wizard
An assisted design mode was put together to help you get started with partial designs. The Partial Wizard offers the
same functionality as the Partial station, with the addition of the benefits of a linear and guided workflow. The
Wizard mode is quick to learn and easy to use.

Adjacent scan
In the Wizard workflow of the partial scan, a new step was added for scanning an adjacent. This window launches
automatically after the model scan to perform a precise-scan of the requested adjacents.
Take screenshots
At any time during the workflow, this camera button captures the complete DWOS software window and saves it
automatically in the desktop folder. The .png files created are useful
for communicating about your digital workflow with clinicians:
engage dialog, share concerns and ensure you deliver the best
possible results. Also, this screenshot button facilitates submitting
a request to Dental Wings support. The default destination for the
.png files has been set in the desktop, but you can change it to the
location of your choice.
To define a custom save location
User Preferences > User Preferences > Screenshot Output Folder.

Attach Files
Right from the moment you are creating it, attach a file to the order and both will be
bounded together. From that moment on, the file will follow the order wherever it
goes, making sure important complementary information accompanies the order
throughout the end, until the prosthesis fabrication.
Desktop icon
Upon 3.9.0 install, a shortcut is created on the desktop to launch the Wizard assistant. On the landing
page, select the desired workflow 1. You are then guided through every step to successfully complete
your case, even on first experiences.
1- Double-click
2- Authenticate
3- Ready to use the assisted mode
More in the Wizard
Users who don't have the implant module can now scan an implant case mounted with a TiBase and design a
custom abutment on the TiBase.
1With the release 3.9.0 of DWOS Lava Edition, the following restorations can be scanned and designed with the Wizard assistant: all prosthesis types of the crown &
bridge module, bite splints, orthodontic models, and partials.

Inferior bar: expansion parameter
When designing an inferior bar, the Bar options window displays this new parameter. Adjust it by sliding the cursor
on the scale. It controls the width at the edges.
It applies only to bars that have the appropriate damping (see image), with a wider edge on one side or on both
sides.
Figure 6-1: These 3 profiles can have an expansion parameter
Figure 6-2: Set the expansion parameter with this slider
Clasp damping
The computing of the damping of clasps is
now smoother. Use the minimum thickness
field of the Clasp options window to
determine the size of the narrowest part. The
decreasing in size is even until it meets the
minimal thickness value and is finished with
a rounding. The reduction factor is
automatically adjusted to the length of the
clasp.
