📖 How to Design Restorations Using Prepared Data > Crowns

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.

 

Positioning Tools

	Free Move/Scale	Move the tooth freely without any constraints. Use shortcut keys to rotate and scale it.
	3D Manipulator	Scale, move, or rotate the tooth.

 

Shortcut Keys (for library data)

Rotate Rotate the tooth in any direction. (Ctrl/Cmd + click and drag)
Uniform Scale Enlarge or shrink the tooth equally in all directions. (Shift + click and drag)
Non-Uniform Scale Enlarge or shrink the tooth along one axis. (Shift + Ctrl/Cmd + click and drag)
Free-Forming Move parts of the tooth to change its form. (Alt/Opt + click and drag)

 

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.

 

Sculpting Tools (Check more hotkeys for sculpting by clicking the question mark; provided hotkeys help save time when sculpting.)

	Add	Add material to the restoration. Hotkey: 1
	Remove	Remove material from the restoration. Hotkey: 2
	Smooth	Smooth parts of the restoration. Hotkey: 3
	Morph	Morph the material on the restoration by dragging it with your mouse. Hotkey: 4

 

6. If satisfied with the result, save the crown to Medit Link by clicking “Complete” in the bottom right corner.

 

7. If you want to make additional changes to both the outer and inner surfaces of the crown, click “Advanced Edit Mode.”

 

A) Edit the outer surface by performing the adaptation with tools provided in the outer surface tab of the Editing Tools.

 

Editing Tools (Outer Surface)

	Adapt to Adjacents	Adapt the restoration to adjacents.
	Adapt to Antagonists	Adapt the restoration to antagonists.
	Smart Adaptation	Adapt the restoration to the antagonists and adjacents simultaneously based on our recommended parameters.

 

B) Edit the inner surface by adjusting the insertion path arrow and changing values for the parameters provided in the inner surface tab of the Editing Tools. Adjust the insertion path by moving the arrow or try using the Set Arrow to Your Viewpoint to quickly set the insertion direction to your viewpoint.

<The gray arrow indicates the automatically set insertion direction, the blue arrow is the newly set insertion direction.>

 

In the prepared data module, you can adjust following parameters for the inner surface of the crown.
