Crowns
1. Register a crown in the form and run Medit Temporaries. After the app has opened, select the prepared data module and assign your scan data.
2. Use the Margin Line Tools to draw a margin line for the prepared tooth. The app supports both manual and automatic margin line creation.
To create a more precise margin, you can turn on Curvature Display Mode and refer to the cross-sectional display that appears when you hover the mouse over the data.
When done, click “Next” or press the space bar.
Margin Line Tools
Manual Creation | Manually create a margin line based on the selected points. | |
Edit | Edit the margin line. Add, move and delete the control points. | |
Auto Creation | Automatically create a closed margin line based on the selected point. | |
Delete | Delete the margin line. | |
Curvature Display Mode | See curvature of the data through Color Map. |
3. A library tooth will appear in this step. Use the provided Positioning Tools to adjust its position, size, and shape. Utilize the contact features in Viewing Tools to ensure proper positioning of the library data on the prepared tooth. These features will show how the restoration fits in with its adjacents and antagonists through the Color Map.

4. Check options provided in the Quick Settings before moving to the next step.
5. Review the created crown. If parts of the restoration are too thin, they will be displayed in blue. Sculpt them before finishing.
