3 New features Post & Core 5Series, iseries, 7Series Available soon on 3Series with dedicated holder Figure 1: Post & Core Figure 2: Post & Core on preparation with overpressed crowns Now available: Post & Core Full crown on Post & Core Reduced crown on Post & Core Post & Core with overpressed crown in the Design station It can be designed from the impression scan of a nerveless preparation. Note that, for insertion purposes, the post & core restoration may be designed on single core cases only. Steps to scan and design a post & core: 1. Create an order with Crown for Prosthesis family and Post & Core for Prosthesis subtype. This subtype must be enabled for the material you are using. in the Material Management > Elements available 2. Route the order and launch the Model Scan station. 3. Scan the post and core impression. 4. Once you reach the design parameter step: Place the margin line (green) on the cervical area. This line is used for building the full anatomy. Place the cut line (in red) on the preparation line. This line delimits the core. Set the insertion axis (green arrow) manually: move the view so that you can see as much as possible inside the nerve canal. Then click the button. Dental Wings Inc. - Page 3 / 27

4 Set the outer (telescope) axis (blue arrow). This will set the outer walls' angle and define the insertion axis of an overpress or other crown that might be designed over it. 5. Route out of the Scan station and process in the CAD Engine. 6. In the CAD station you could: compute an overpress crown from the right-click menu adjust the margin line use any shaping tool change the prosthesis type to Reduced or Full crown on Post & Core with the Recompute function. Figure 3: Cervical line (green) is placed on the gingiva. Cut line (red) is placed on the preparation edge. Figure 4: Set the insertion axis for the post (green arrow) and the telescope axis for installing the overlay restoration (blue arrow). Both are set in the insertion axis window.

5 Custom gingiva former 5Series, 3Series, 3Series+, 7Series Figure 5: Gingiva former designed on an implant planning Figure 6: Once recomputed into a custom abutment, the radical area preserves the same shape to fit perfectly the healed tissues. Figure 7: Section view: the design that was done on the gingiva former is preserved on the radical part of the custom abutment 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. Workflow example to design a custom gingiva former: 1. Open Order Management 2. Import a.xorder of an implant treatment planning 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: Drag this order Click Yes to adjust vertical axis Rotate the view to obtain an occlusal view and click OK Position the arch on the model 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. Dental Wings Inc. - Page 5 / 27

6 Define an insertion axis for the abutment by rotating the view and clicking Repeat margin and axis definition for every implant location Exit 4. Process in the CAD Engine 5. In CAD: A custom abutment is automatically calculated Right-click on it and select Recompute In the Prosthesis Type tab, select Custom gingiva former You can use all shaping tools to form the healing device for the cases needs. Gingiva former parameters The automatic proposition of the gingiva former is computed from a set of parameters that you can access through: Figure 8: Material Management > Custom Abutment Parameters Figure 9: Set computing parameters in the CAD station with the Recompute function. Dental Wings Inc. - Page 6 / 27

7 Egg shell Figure 10: Egg shell temporary Egg shell temporaries can be created from the scan of a natural tooth prior to its trimming. In the CAD station, therecompute 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. To create an egg shell temporary: 1. Create an order with a diagnostic crown. 2. Scan the model of the full anatomy. 3. Once in CAD, right-click on the prosthesis and select Recompute. 4. Click on the coping parameter tab. 5. Activate the Compute virtual preparation checkbox. 6. Under it, select the checkboxuse Egg shell shape. 7. The recompute feature will occur when you click OK.

8 Saw cut models Model Builder You can now create models that will simulate a saw cut model and will be able to fit your Dentona or Baumann plates. Figure 13: Saw cut model on Baumann plate Figure 14: Model on Dentona plate We are saying "simulate" because the model will be 3D printed in separate volumes, as if it was sliced by a saw cut. This imitated the hand-crafted models that are cut afterwards. You can design the cut lines to your will without the real tool constraints of creating only straight lines. 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. Click and drag the plate to position around the model 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 Dental Wings Inc. - Page 8 / 27

9 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: Move it with the central blue dot. Rotate it with the blue dot on its edge. Use the green dots to curve it. 6. Axis mode: the path that you have defined with the Spline mode can traverse the model with a custom angle. 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 rightclick) 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. Figure 15: Right-click on a computed model to generate saw cut lines Figure 16: The editor window for saw cut planes has 2 modes: spline and axis Moreover, you can apply cut lines to any types of models. You are not restricted to the above mentioned brands of plates to create models that simulate a hand-crafted model that was segmented. Dental Wings Inc. - Page 9 / 27

10 Mono block models Model Builder Figure 17: Mono block model 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 and a replica of the stumps is manufactured on the side, on its own base. Use this stump type with any type of model. Zimo models Model Builder Figure 18: Default model with Zimo articulator Figure 19: 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. 3. Drag and drop the order in the Model Builder station. 4. Stumps parameters: Select Zimo Pin shape Leave default parameters to begin, then come back (Select recompute from the stump rightclick menu) 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. Dental Wings Inc. - Page 10 / 27

11 Custom Profile Editor (for wrap-around and hybrid bars) Figure 20: 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 and import/export profile libraries. To create profiles: 1. Right-click on the Bar profile folder in the left pane and select Create Bar Profile. 2. Name your new profile. 3. In the Bar Profile Editor window, deactivate the Edit tangents and Measure modefeatures. 4. Design the profile to your needs: Move the dots by clicking and dragging them. Click and release a dot to delete it. Click on the line to add a dot. 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. The profile designs that you save will be available in the CAD implant bar editing window: Bar mode > Profile > Custom Dental Wings Inc. - Page 11 / 27

12 Open the Bar Profile Editor from the Settings icon Figure 21: Use the Bar Profile Editor window to access a variety of drawings and measuring tools to create your own profiles. Figure 22: When you save a custom profile, it becomes available in the Bar profile editor window in CAD To manage profiles With a right-click on the 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. Dental Wings Inc. - Page 12 / 27

14 Improved features Model Builder 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. Dental Wings Inc. - Page 14 / 27

15 Wax-up Add dental band Figure 24: Dental band on reduced waxing scan. You can apply a global reduction parameter to the waxing with the Reduce waxing function. Now, with the new Advanced dental band on wax-up, you can apply a reduction parameter to a defined area of the waxing. Advanced dental band: 1. If you are working on a full virtual wax-up, select Merge from the right-click menu. The defined area turns into blue. 2. Right-click on a waxing and select: Waxing > Advanced dental band. 3. Draw freely on the surface with the lasso mode. 4. Edit the line to your needs: Move the dots by clicking and dragging them. Click and release a dot to delete it. Click on the line to add a dot. 5.

18 Virtual waxing Edit connectors When a full virtual waxing is computed without gingiva, non-touching teeth are automatically linked with a connector that you can edit. Reminder: a full virtual waxing is created by activating the check box in the Arch scan parameter window. Figure 30: Reminder: the virtual waxing is generated by activating this option in the scan session 1. In the CAD station, right-click on gingiva and select > Delete. 2. Connectors are computed where needed and you can right-click on them to edit. 3. Thanks to the multi-editing mode, once the connector editor window is open, click on another connector to start editing it without having to validate and right-click again. Figure 32: Right-click on a connector to edit. Figure 31: Delete the gingiva of the virtual waxing from the right-click menu Dental Wings Inc. - Page 18 / 27

19 Gingiva base line The base line of the virtual gingiva is computed from the scanned gingiva for the automatic proposition. But you can editit to your needs by modifying it or redrawing it. Figure 33: Gingiva base line shown in green Gingiva baseline editing 1. Right-click on a virtual gingiva. 2. Select Edit Gingiva Base Line Figure 34: Freely draw a baseline on the scanned gingiva from where the virtual gingiva will be computed 3. To edit the existing line: Move the dots by clicking and dragging them.click and release a dot to delete it.click on the line to add a dot. 4. Or you can select Clear line to delete the existing line and draw a new one: Turn off the layers that block the view of the scanned gingiva Freely draw with the mouse a contour for the base line of the virtual gingiva. Move the dots individually to perfect the area Dental Wings Inc. - Page 19 / 27

20 Implant bars Edit parallelism When designing a telescopic prosthesis from a virtual waxing, the Adjust axis tool is available to set their outer axis. 1. If you need to recompute the prosthesis within the virtual waxing into telescopic copings, right-click on it and select Prosthesis > Recompute overlayand set to telescopic copings. 2. Then from the same right-click menu, select Adjust Axis. 3. Form a group by selecting all teeth that need to have the same axis and click the "+" icon. 4. As you move the axis of a telescopic crown, all the copings within this group are tilted at once. Figure 35: Right-click menu on a virtual waxup Figure 36: Adjust axis editor Bar parameters The new parameters are more intuitive to set Milled bar profiles by typing a narrowing angle instead of different lengths. 1. In the CAD station, right-click on an implant bar. 2. Select the Segment mode. 3. Set the profile to Milled bar. 4. Set the maximum width and height. 5. The value set in the angle field will determine the width at the top of the bar. Dental Wings Inc. - Page 20 / 27

21 Chamfer plane To add a chamfer plane to a bar pillar: 1. In the CAD station, right-click on a bar pillar and select Edit implant bar 2. Activate the pillar mode 3. Click on the pillar that you want to chamfer. 4. Click on the Create chamfer button at the bottom of the editor window. The same button turns into Remove chamfer 5. To position the plane: use the yellow dot to move that you can use to delete the plane. use the green dot to rotate (the current view affects the rotation axis of the plane) 6. Click OK to validate or; Click on another pillar and on Create chamfer or; Continue editing the bar by selecting segment, bar or attachment modes. Figure 37: Result on chamfer plane after merging Attachments on bars 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. Access your implant bar library while using the bar editor by activating the newly integrated 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. Dental Wings Inc. - Page 21 / 27

22 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 next section: Attachment hole compensation. Figure 38: New bar parameters: set them in the bar segment editor Figure 39: Chamfer plane: create them in the bar pillar editor Figure 40: Attachments: add them directly from the bar editor 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". Dental Wings Inc. - Page 22 / 27

23 Figure 41: When quitting the CAD station, merging is mandatory for bar designs: it is selected and grayed out Figure 42: Hole compensation result after merging Figure 43: This is where to set the minimum thickness which determines if the design needs compensation. Retention Beads Figure 44: Adding retention beads on a framework bridge made of clinical copings You can now add them to any framework restoration. Apply them to: 3/4 crowns Simple copings Reduced crowns Clinical copings Telescopic copings Virtual Waxings Dental Wings Inc. - Page 23 / 27

24 Adaptation environment This step lets you identify a subset of dental points on the surrounding teeth, so that the CAD Engine is able to analyze the context from the provided information. This is part of the strategy to improve automatic prosthesis propositions. In order to use the improvements featuring 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 adapt button to refresh the design. Figure 45: Placing Adaption reference points on the antagonist Dental Wings Inc. - Page 24 / 27

25 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 46: These 3 profiles can have an expansion parameter Figure 47: Set the expansion parameter with this slider Dental Wings Inc. - Page 25 / 27

26 Custom abutments 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. Figure 48: Displayed angle between insertion axis and the custom abutment outer axis Manufacturing tool compensation These new parameters under Material management > Manufacturing parameters apply to custom abutments Dental Wings Inc. - Page 26 / 27

27 Shaping tools 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. To apply the interactive deformation you just have to click on any colored handle and move it. You can manage the resulting surface deformation according to 2 modes. NEW: Global When you activate the Global deformation, moving a handle impacts the surrounding handles: they will move according to morphological transformation, so that the general anatomy is preserved. This mode is perfect to apply 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 49: Initial shape Figure 50: Global deformation affects other handles around the one you are moving Figure 51: Local deformation offers more handles but only one can be displaced at a time 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. Dental Wings Inc. - Page 27 / 27
