19 How to Handle Trios Scans and Design Models in Model Builder. TRIOS orders appear listed in the 3Shape Communicate inbox tab. Once you have accepted a TRIOS order it is transferred to the orders tab of Dental Manager. TRIOS orders contain "raw" scans and must be prepared in Model Builder before CAD design. The following steps illustrate how to handle a Trios Scan: Step 1. First go to the Trios Inbox to select the case on which you wish to work. Step 2. Next, right click on the case and select accept. Note: You can also select 3D preview to examine the scans before accepting the case. Step 3. You will have to select the delivery date and you can also add any comments that you wish to send to the client. Step 4. When you enter the Order form you can examine the case in more detail by looking at the 3D preview and the Trios order form send with the case. Click on Ok to move onwards.

20 Step 5. An Automatic conversion window may appear if the case details differ and you can accept the conversion by pressing Save. You may also right click on the conversion rule if you wish to make changes. Note: If you wish to create a die-ditched model, make sure to select this on the order form. Step 6. Back in Dental Manger you can now right click on the case and move on to designing the restoration. In this workflow we will design a full anatomical crown and also design and produce a model for production. A workflow bar will appear, and the first step is Preparation of the digital impression. Step 7. At the occlusal alignment stage, you can drag and rotate the blue alignment plane into a preferred position. Click Next to move on. Step 8. If necessary, you can trim the upper jaw to remove any excess data that will not be required. This can be repeated for the lower jaw.

21 Note: By clicking the Show opposite jaw profile you can see an overlay and using this you can trim to the match the upper jaw. Step 9. The final step in Preparation is to use the Sculpt toolkit to add, remove or smooth material on the scans. When satisfied, click Next to move on to setting the margin line for the die. Step 10. To initialize the margin, click on the top of the tooth and an initial margin will be placed. You can adjust this by left clicking the mouse button and dragging a new line. Click Next when satisfied. Step 11. At the Directions step, the insertion direction is calculated for you. It is possible to make adjustments by using the keyboard arrows or by using the mouse to place new green dots along the model. When satisfied with the insertion direction, press Next to move on to the next step.

22 Step 12. The Interfaces step is where the margin line for the anatomical crown is placed. It is automatically placed for you, but again you can adjust this by clearing the line and placing a series of points along the margin. A cross section tool will appear to help you identify the margin. Remember to close the line by clicking the start point which will turn yellow. You can make further adjutments by clicking and dragging the points into a better position or by clicking ang dragging to draw a new line Step 13. Once satisfied that the margin is clearly identified, click Next to set the Die interface. Here you can add parameters to the die interface depending on materials and production processes that you adhere to. You can choose to Preview the interface or just click next to move on to the Anatomy design step.

23 Step 14. In this case the full anatomical crown will be designed and placed automatically. There are a range of tools to help you adjust this design. Please see Appendix: How to Use Smile Composer and Sculpt Toolkit for more information on this topic. Step 15. After making any adjustments to the anatomy design, click Next and the design will be saved. You are now ready to build the model. You can examine the design, lift off the indication and use the visualization tools before going back to make changes or clicking Model to move on to Model Builder. Step 16. If corrections are required, repeat the preparation steps done in Dental Designer, otherwise skip to the Section scan step by clicking Next. Step 17. At this step, you can section the die by drawing a cut-out line. Typically you will just reuse the margin line already set in Dental Designer, but for some cases like inlays and onlays it is useful to set the cut out line below the margin line. Note: Setting the cut-out line can be done from outside and inside of the scan and with different color options

24 Step 18. You can also section neighbors in your scan by clicking the Neighbor button. Then, select the top of the neighbor, or drag the mouse around the margin line, and edit the die cut-out line. Step 19. If you wish to do the same for the second neighbor, repeat the procedure. When satisfied, click Next to move on to the next step where dies are automatically generated.

25 Step 20. At this step you can check and adjust the insertion directions of individual dies. Click the die to make it active and adjust its position by dragging the axis. Clicking the Set Insertion Direction button sets the insertion direction from the current view. Click Apply and then OK and go to the Articulator Interface step. Step 21. Here, you can select a specific articulator model and choose whether to add an ID tag to the model and dies for easy matching if you print in higher volume.

26 Step 22. You can now rotate your interface to find the desired position by clicking the model and dragging or using the red control points. Note: If the design of your restoration collides with the model design, you can select the Substract design from digital jaw model option and that part of model will be removed from the model when you click OK If you wish to save time and material during the printing process go to File in the top left corner and then click Virtual Trimming Settings.. Step 23. On the window that opens you can select settings for hollowing models.

27 Final sculpting of the models can be done if necessary. To do that, go to Final Sculpt and use the Sculpt toolkit. Within the Sculpt toolkit you can also add attachments to the model. Click Ok when satisfied, which means that all models have been saved and you can close the Model Builder. Note: If the Sectioned model option was specified in the order form, make sure that at the Articulator Interface stage you have selected one of the available interfaces for sectioned models then complete the virtual model design as above. Before you close such a case, you must perform the cutting of the indicated jaw by placing the cuts on the model and adjusting by using the control points. The software will cut the model and save the design.

29 How to Follow the Smile Design Workflow. Smile Design is a planning tool which can help you communicate with the Clinic and the Patient. Smile Design is included with Dental System Premium. Follow the instructions below to complete the workflow for Smile Design: Step 1. Start by adding a new patient and creating a new case. Step 2. Once you reach the order form page, select Smile design from the indications list. You do not need to select any teeth in the overview window. Step 3. On the right side of the screen, you must now select Comments and attachments.

30 Step 4. Select the blue + icon to add clinical photos of the patient. You can attach a smile photograph alone, or also add a retracted smile photo if the patient doesn t show gums while smiling. Step 5. Once you have uploaded the photographs, click Next to move on to the next step. Here you must click and drag the photographs to the corresponding placeholder.

31 Step 6. At the next step, you have to find the balance of the face by placing 3 sets of reference points; the pupils, the nasal wings and the commissures. You can adjust any of the points by clicking again, or clear all the points and start again by clicking the red X. When the photo is balanced, a blue lip line will appear. That line will be used later on to create shadowing on the design. The placement of the lip line can be done by dragging the control points, clcking the points on the picture or by drawing the line on the picture. The magnifier will help with accuracy of placement. When ready click next to perform alignment of the photos, if more than one was added. Step 7. To align the photos you need to place 2 sets of corresponding points on the photographs. Once you placed the fourth point the combined, overlay photograph will appear in the main window. Note: This step is only available if you have added more than one photo. Step 8. You can continue to move the points to align the photographs to your satisfaction, or clear all the points and start again by clicking the red X. when satisfied press Next.

32 Step 9. The next step is the smile design page. In the central window there is the suggested teeth design and smile frame guidelines. On the right of the screen you can find visibility sliders which you can use to turn on and off various on-screen objects: Hide the Smile frame Turn simulated teeth texture on and off Switch between smile and retracted photos if available Step 10. Firstly, you can change the overlays by going to the Smile Library drop down list and selecting the desired shapes. If you click twice, then you can flick through the libraries using the up and down arrows on the keyboard. Step 11. You can remove teeth that you do not wish to treat by selecting them, the outline will turn blue and then press delete on the left side of the screen or Delete on the keyboard. Step 12. If you hover over the smile frame, the control points will appear. Use it to move the overlay up and down and shift it to the sides to align to the midline of the face. Step 13. Scale it vertically using upper and lower control points or scale the width using side control points. While doing that, you can see the change in the percentage of the height to width ratio.

33 Step 14. Now you can also use the gingival and smile curves control points to adjust it in relation to the commissures and change the perspective of the teeth outlines. Step 15. By default Smile Design opens with the Transform tool being active. Any tooth, when chosen and activated, can be transformed by clicking on it and dragging. Step 16. In the default setting Symmetric design and Linked design are both activated. Symmetric design allows you to work on the chosen tooth and the contralateral tooth at the same time and linked design allows you to adjust the tooth and its neighbor at the same time. While both tools are active you can use the full adjustment possibilities provided by the software, which is symmetrical adjustment to all the guiding lines and the design of the whole smile. Step 17. The Freeform tool allows you to change the shape of the tooth by drawing its outlines or by clicking on a chosen point. When you hover the mouse, a prediction will appear. Note: the radius of the tool can be adjusted by using the slider or by holding shift and scrolling the mouse wheel. Step 18. The next step allows you to use the simulation tool where you can change the texture library on the teeth.

34 Using sliders you can also adjust Shade and Brightness of the simulation. It can be done for all of the teeth involved or just for some of them by selecting them. Use Auto color to restore to the default suggestion. Highlights and Shadow from lip can also be adjusted for even more realistic simulation. That can also be improved by Photo edit tool allowing gums adjustments if necessary. Step 19. When the smile design is ready click Next to move on to the Presentation step which allows you to compare the design outcome with the current dentition by clicking and sliding the blue central slider. Step 20. The Export photos button allows you to choose the location and export the photos in PNG format, which you can send via . Step 21. You can send the case via 3Shape Communicate to both the Clinic and Patient for approval.

35 When opened in Dental System, the outlines can be used in conjunction with the RealView Engine to design restorations. Step 22. On the order form page, click the green plus icon and add the pictures exported from the Smile Design application. You can Import the original smile photo and the one with the new smile design. Step 23. Once the order has been created follow the usual workflow path of preparing a scan, setting the insertion direction, the margin line and die interfaces. Step 24. While in the Anatomy design step enable the RealView Engine by selecting it from the tool on the right-hand of the screen. Both photos can now be seen on the right within the visibility sliders. The photo is already aligned from the Smile Design application so you will not need to do it here. Step 25. Set the cutout line where the design needs to be visible through the photo by placing a series of points. Place the spline around the teeth and gingiva by placing the control points with the cursor. To close the spline, click on the first point. Note: Right clicking on the spline gives the option to clear it.

36 Step 26. Place reference points on both the picture and scan to align it together. Step 27. You can change the tooth color sampling area by moving around the red square on the picture as well as by changing its size by holding Shift and scrolling the mouse wheel. Step 28. Use the smile design picture to guide the restoration design according to the treatment plan and use the smile picture to assess the design. Note: You may freely switch between the two photos by toggling the sliders.

37 How to Perform a Workflow Using the RealView Engine. 3Shape s RealView Engine provides a near photo-realistic visualization of the patient case, that brings together the patient s smile, the designed teeth, the existing teeth, and the gingiva. The result can allow you to verify the design in relation to the patient s smile. Follow the steps to complete the workflow: Step 1. Start by creating a new order and choosing the required type of restoration, material and type of impression, which can be both intraoral scans as well as scans of plaster models. Step 2. Next, under Patient information on the left of the screen, you can add a clinical photo that will later be overlaid on the 3D scan by clicking the green plus icon. Now browse for the photo that you wih to attach to the case. You can add more than one. Step 3. Once the order has been created follow the usual workflow path of preparing a scan, setting the insertion direction, the margin line and die interfaces.

38 Step 4. When you reach the Anatomy design step, use the Smile Composer s Smile Library to choose the correct shape of teeth. Step 5. Use the available Sculpt tools to adjust the shape and size according to any requirements. Step 6. Click the Real View Engine icon in the Viewing tools bar and the RealView wizard appears with the 2D image that you have added earlier. Note: If you have not added any pictures, a browse dialogue, offering you to upload the 2D images from a chosen folder will appear. The Real View window that appears with a picture contains a four steps workflow bar situated on the top. Step 8. The first step of the Real View Engine allows you to set two points of the horizontal line across the pupils of the eyes. That line will keep the smile occlusion parallel with the eyes. If the angulation of the line needs to be adjusted click on one of the points and move it. Note: Clicking on the line gives you the possibility to shift it with no change in angulation.

39 Step 9. You can add more horizontal and vertical guide lines clicking on the plus button and then on the picture in desired location. Step 10. Right clicking on a point or line enable you to delete that line or all lines. Step 11. The second step is setting the Cut out line for scan and design. This enables your 3D design to be seen as a 2D image. Place the spline around the teeth and gingiva by placing the control points with the cursor. To close the spline, click on the first point. Note: Right clicking on the spline gives the option to clear it. Step 12. You can cut out the gingiva from the teeth with the Fast edit option for better esthetics of a designed restoration. Note: Press Ctrl and scroll the mouse wheel to change the influence radius of the cut-out spline. Step 13. After setting the Cut out line, move to the Alignment step where you place four matching pairs of points on the image and on the preparation scan. Click on the points in turn - one point on the preparation scan and then the corresponding one on the image. After the last point is placed, the software automatically aligns the image to the scan.

40 Step 14. By changing the visibility of the image you can check if the scan and picture have been aligned correctly. You can move points to adjust alignment if necessary. Step 15. At the Rendering step you can view the 3D design together with the 2D the image where the CAD designed teeth are automatically rendered with the same color as the existing neighboring teeth. You can change the tooth color sampling area by moving around the red square on the picture as well as by changing its size by holding Shift and scrolling the mouse wheel. Step 16. While 2D picture is overlaid on the scan you can adjust the design by using the Sculpt tools to match it with the smile. Step 17. To come back to design mode, use the Patient image slider or click the Real View Engine button. This means that you have successfully competed the workflow for using the RealView Engine in Dental System.

41 How to Perform a Workflow for a Physical Wax-up. In a situation when a patient deals with discoloration of teeth or is dissatisfied with their shape, a physical wax-up can be made in Dental System.

59 How to Use the Smile Composer and Sculpt Tools in Dental System. In Dental System at the Anatomy Design step you can use the Smile Composer which includes the Smile Library and the Sculpt tools. It is available for crowns, pontics, bridges and full dentures. Dental Designer automatically places crowns and pontics. Below is an overview of the available tools and how to use them: The Smile Library consists of a selection of libraries which you can choose to use. Simply select the library you prefer, then click Preview before clicking Ok. You can select single teeth or all in the group by selecting at the bottom of the list Global transformations is a tool that can be used for multiple teeth restoration and allows you to move, scale and rotate all teeth in a restoration. To move your restoration, click on any point of the tooth and drag it sidewise.

60 Drag the green points to change the shape of a whole restoration by moving it sidewise, back and forth or up and down, depending on the view. Note: Holding down Ctrl and mouse move switches the scaling mode from onedirectional to proportional. Depending on the view, tilt and rotate the teeth by clicking and dragging one of the red points. The adjacent arrows illustrate the direction of the orientation. The Arc transformation tool lets you move a restoration composed of more than one tooth into an optimum position. Hover the mouse cursor over a tooth in the multiple restoration and adjust its position while keeping the left mouse button pressed. You can adjust the number of teeth the transformation affects indicated with the blue circle. The size of the circle can be changed by using a slider or by rotating mouse wheel while the CTRL key is pressed. If you want to scale or rotate a single tooth, hover the cursor over the selected tooth and its control point, then use the mouse wheel. Double click on control point to change the mode.

61 The Individual transformation tool can be used both for a single restoration and a single tooth in a multiple teeth restoration. This tool allows you to move the design, scale and rotate it using points on the design. The view of all points changes depending on the view direction. Right-click on a tooth to display the options that allow you to move the design to mesial or distal contact and into contact with the antagonist. Individual Morphing allows you to move points on the tooth in the desired direction. The net around a cursor shows direction the morphing is applied and a green circle shows the affected area. Hover over the point, hold Shift and scroll the mouse wheel to change the radius of the affected area or use a slider in the design tools window. Points are divided into different color groups and you can drag them separately or hold down Shift to move the entire control points group. Change the radius around the entire group by holding Shift and scrolling the mouse wheel Hold Ctrl and move your mouse up and down to move the chosen point along one line. Hold Alt and left-click to add or remove control points.

62 The Wax knife tool allows you to add and remove material to and from the design and to smooth its surface. Choose one of the three options and click on the design to apply the operation. Select the radius and level of the influence of the wax knife by using the two slide-bars. Alternatively, use Shift + the mouse wheel to change the radius and Ctrl + the mouse wheel to change the level. Apart from those three buttons, the wax knife also has the threshold button that limits adding and removing material to the value set with the sliding bar. Threshold can be measured from the preparation scan to adjust tightness of contact point, antagonist scan to get a light or a tight occlusion, die interface or neighboring teeth undercut to get a broad contact. For example you can adjust contact points by removing material. Choose the Preparation scan button. Set the value and adjust the design. Material will be removed only to the chosen value. You can set that value as the default for one of the buttons. Click the record button and the button under which you wish to keep these settings.

63 The Attachment tool allows you to place an attachment to the restoration for any indication. In the Attachment settings you can select the Group of an attachment and its type as well as set Default orientation, for example the insertion direction or the view direction. The chosen attachment can be set in the desired place and modified by using the spheres. To save it, click the Apply button. To add attachments one by one, just mark the checkbox. Then you can add a new attachment just by clicking on the restoration. You can also select the cut by gingiva option to have it cut to the gingiva The Plane cut tool allows you to cut your restoration with a plane. You can move and adjust a plane by using spheres. The Smoothing parameter lets you adjust the amount of smoothing of the cut edges with the slide. In case of two neighboring teeth being modeled you can check the Cut between teeth checkbox and define a width of the cut in the Space field.

64 Contacts and smoothing allows you to smooth the entire surface of a restoration, set the level of occlusal attrition as well as set and enforce minimum thickness, the distance to the antagonist, the precise cut to the antagonist and the distance to neighbors. After setting all the necessary parameters in the box, press the Apply button to have it done for a selected tooth or apply to all to have it done for all designed teeth. The Auto placement tool allows you to set the distance to the antagonist or to neighbors. Just fill in the value of the desired distance and click the apply button. Please note that this option is not applicable for a bridge. The Mirror Tool can be used to copy another tooth. There are three options: When you have one crown modeled, you can mirror its design to the symmetrical one by positioning the cursor over the mirrored crown and clicking the mouse button when the blue arrow points at the crown to copy the design to You can also copy a tooth from the preparation. Make sure to use a birds eye view before selecting the tooth you wish to copy. Also, an individual tooth can be mirrored from its pre-preparation or wax-up scan. For the feature to work, most of the surface of the modeled crown must be positioned inside the surface of the corresponding pre-preparation or wax-up scan.

65 Connection to the margin line tools allow you to Connect the designed anatomy to the margin line and disconnect it if needed The Simple connection checkbox allows you to connect the design to the margin line without applying extra smoothing to the anatomy near the margin line, keeping the design unchanged. For more information on using the Virtual Articulator, please see our separate Appendix: How to Use the Virtual Articulator. Note: If a Dentist using Trios Intraoral Scanner has recorded the patient specific motion during the scanning process you can also access the Patient specific motion tool. Enable it by choosing the option from the dropdown list or from the visualization tools on the right of the screen. Press the play button, see the movement of the jaws which was registered by the dentist. Now, you can see the contact points, that have been recorded during the scanning process. The hard contacts have been marked with a yellow color. Adapt the design to the registered contacts, with minimum thickness accordingly, by pressing the Adapt design button. The Reset design tool allows you to reset the modeled restoration to the default. Just select the desired tooth and click Apply. Using the Apply to all button you can reset the design on all teeth.

99 How to Maintain your Dental System Installation. In order to keep your PCs and 3Shape Dental System functioning as well as possible, you may see some improvement by managing the size of your material file and the amount of orders in your database. Below you can find some advice: Consolidate all licenses onto one dongle: In some systems, it has been found that the use of multiple dongles leads to longer read times, especially when using three or more dongles. Therefore, we currently advize working with only one dongle containing all licenses. Resellers are able to consolidate licenses for Dental System. Show limited amount of orders: Opting to show a limited amount of orders will result in the system running faster. You will see a difference during the Dental Manager startup and when using the search function in Dental Manager. The option can be enabled in the Dental System Control Panel. Go to Dental Manager > General > Database Settings. Tick the Show limited number of orders check box and set the amount to maximum 200.

100 Remove old orders from your database: When handling a big load of cases, it is crucial to maintain the database and prevent it from being filled up with old cases that no longer need to be in the database. This could slow down the performance of your 3Shape Dental System, especially Dental Manager, In Dental System 2018 we have introduced automatic clean up in orders that are left over. To enable an automatic cleanup of the database, go to Dental System Control Panel > Dental manager > Automatically delete orders. To ensure that you only delete the files from your database and yet still keep the order files on your storage disk, tick both the Enabled and Keep files but delete from database check boxes. Also, set the amount of days you would like to keep your orders. It is recommended to set this between 30 and 60 days. However, this period should be shortened if you have a high daily order volume. Trim your material file: Try to remove all materials you don t use because the size of the material file also has an influence on the performance of 3Shape Dental System. The material file is read every time Dental Manager is started up or when an order form is opened and the bigger the material file, the longer it will take. Also generating the CAM output will take longer when working with big material files. If you really need all of the materials, consider looking into a multiple Client-Server solution with divided material files for crowns and bridge work and another for other restoration types.
