scanning protocols for guided solutions.
- 1. -Dr Shahbaz Qureshi. − System Requirements − Specification Scan protocols for guided solutions.
- 2. Guided surgeries Implant dentistry has shifted from a “surgically driven approach” to a “prosthetically driven approach”, because appropriate implant positioning is crucial to achieving long-term funct ional and esthetic success. In the meantime, computer-guided implant surgery has been developed for over two decades. This digital technology is now commonly recommended because it can reduce inaccuracy in terms of implant positioning.
- 3. Guide preparation Workflow Scenarios: -Single tooth scanning. -Partially Edentulous. -Fully Edentulous.
- 4. Medit Scan for single tooth scanning for guide preparation. • Full arch scanning with bite scan • Bite registration:. When taking a bite registration, the patient is instructed to bite down and hold the mouth closed while the scanner is inserted between the cheek and the posterior teeth. • Scanning should start from posterior region towards anterior in zigzag motion in occlusion for proper bite alignment. • ProTips: Error 1)-The patient doesn’t always know what their bite is. They clench in the wrong position thus giving an incorrect bite. It’s best to guide the patient into the correct centric relation and then scan. Error 2)When the patient slightly opens their mouth while the scanner is moving in the mouth. To avoid from taking an improper bite registration, have your assistant either hold the patient’s mouth in position or ask the patient to bite on bite paper, and the assistant can pull on it while scanning to make sure the patient does not open their mouth. Bite scan in occlusion.
- 5. Tips for scanning missing tooth area. Isolation: Be sure to isolate appropriately, which is easier said than done. However, pay attention to the method you use to c ontrol moisture, as some can interfere with data capture. Lighting: turning off any external light sources, like loupe lights and overhead chair lights, is essential. The scanner has an inter nal light that will be best for capturing the dental pictures needed for the scan. Any excess light can interfere with this process of data capture. Scanner holding: When scanning an upper and lower arch, you don’t want to change how you hold the sensor too much. S o, after removing the scanner’s protective tip and replacing it with the mirror tip, we recommend holding the sensor like a pencil, l etting it rest in the pocket of your thumb and index fingerwith the power button accessible easily on the top. Then, you can switch t he mirror tip to facing up or down from this position, depending upon which arch you are scanning.

- 30. Do you recommend a specific 3D printer and material to use with this app? There is no recommended specific 3D printer and material to use with Medit Splints. Medit Software has been tested by a variety of partners, So you can see which printers have been tested here : https://support.medit.com/hc/en-us/articles/7901453692825-Configuring-Medit-Apps-for-3D-printing Manufacturers and printer models will be continuously updated on this page.
- 31. Is it possible to get another webinar or video so I can understand the splint app in a better way? We have our online training platform so that even the beginner users can learn our software easily! Please create an account and enjoy the trainings >> https://academy.medit.com/pages/home-page
- 32. Do I have to have a bite scan as well besides the maxillary scan and the mandibular scan? Medit splints can be used even without occlusal scan data.
- 33. What if I want to build in an anterior ramp for anterior guidance? With one of the sculpting tools “Morph”, you can easily build in an anterior ramp as this image.
- 34. Why not take an open bite record digitally instead of artificially opening the bite with A.I.? In Medit Splints, you can do both. You can use an open bite scan and then occlusal thickness is created as it is. Or you can use a closed bite scan, artificially open the bite, and then occlusal thickness will be calculated automatically based on the occlusal thickness that is used previously.
- 35. If there is a teeth that is missing will it affect this part of the process? If there are missing teeth more than one, a problem may occur when creating the splints. We are trying to fix it for the next version!

Editor's Notes
- The app allows you to create splints either automatically or manually. After assigning the data and selecting an arch for splint creation, choose between Auto Creation and Manual Creation. Depending on your choice, your workflow will be different. Parameter Settings ￭ Clicking "Parameter Settings" will allow you to view and modify the parameter values used in Auto Creation.
- Auto Creation is an AI-powered splint creation tool. The app will create the splint based on the parameters you previously set. 💡 When you run the app for the first time and select Auto Creation, the default parameters will be used. 💡Design Mode and Labeling Mode are optional. Skip these steps and save your project file if you like the auto-created splint. Feedback on Auto Creation You will be prompted for comments on your most recent automatically generated dental splint the following time you use Medit Splints' Auto Creation feature. The app will take note of your response and make automatic parameter adjustments to produce a more precise splint design the next time. 💡Feedback is an optional feature that can be disabled in the settings.
- Manual Creation is a step-by-step splint creation process that gives you more flexibility if you want to fine-tune the splint. Overview Mode ➠ Edit Mode ➠ Alignment Mode* ➠ Occlusal Adjustment Mode* ➠ Inner Surface Creation Mode* ➠ Outline Designation Mode* ➠ Outer Surface Creation Mode* ➠ Design Mode ➠ Labeling Mode ￭ Asterisk-marked modes automatically analyze the characteristics of anterior and posterior teeth.
- Occlusal Adjustment Mode By correcting the occlusal relationship between the maxilla and mandible at this stage, you will be making room for the splint.
- Bite Opening(mm) : In the virtual articulator, adjust the biting opening. Distance to Antagonist(mm) : Decide where the mandibular and maxillary occlusal surfaces are closest. ⚠︎ The distance from the antagonist must be greater than 0. You cannot go to the next step if it is set to 0.0 since there is no room for the splint. Set this value to produce a splint with an appropriate occlusal thickness.
- Inner Surface Creation Mode The inner surface of the splint can be made at this stage. Click and hold the arrow to freely move it and set the direction of the blockout undercut. The data that falls within the blockout area will be highlighted in blue. Press the "Preview" button to see the data with the blockout undercut.
- Inner Surface Offset Set the offset distance from the data to create the splint's mesh.
- Inner Surface Offset Set the offset distance from the data to create the splint's mesh.
- Smooth Surface Smooth out the inner surface of the splint. Move the slider to the right to add smoothness.
- Angle : Set the blockout angle. (0.0 ~ 10.0)
- Angle : Set the blockout angle. (0.0 ~ 10.0)
- Retention : Allows undercut areas to enhance splint retention.
- Outline Designation Mode : In this step, you will draw the splint's outline on the buccal and lingual sides. In Outline Designation Mode, an outline will be generated for you automatically. If you need to change the outline, use your mouse to move the green point or the "Buccal Side" and "Lingual Side" sliders at the bottom. The selected area is highlighted in blue when the data has been correctly outlined. Left-click on the outline to add more green points, and right-click to remove a green point.
- Outer Surface Creation Mode : The outer surface of the splint will be created at this stage. Slide the "Lingual & Buccal Thickness" slider to the right to add splint thickness to both the lingual and buccal surfaces at the same time. The occlusal surface thickness will be calculated automatically based on the distance to the opposite occlusion teeth. Apply the "Smooth Surface" slider to the splint's outer surface to smooth it out.
- Design Mode : This is the stage at which you can make the final design changes to your dental splint. Use the Sculpting Tool to add, remove, smooth, or morph the splint's outer surface. Make fine adjustments to the splint's surface with it. When the Color Map is enabled, the red areas show the data intersections. Check the distance to the opposite occlusion teeth by clicking "Switch Deviation Display Area.“ Analyze the occlusal contact points with the provided tools and cut out splint intersections with opposite occlusion teeth. Use "Measurement Tools" to review the thickness of the splint after sculpting and editing its design. Create section lines on the 3D data and then measure distances by selecting points on the lines.
- Labeling Mode : Labeling Mode provides a toolbox of functions for adding, deleting, and editing labels.
