Select the “Bridge” tool at the bottom of the screen and zoom in on the separated data element. Adjust the “Width” slider to determine how broad the created mesh stripe will be.

Hover the mouse over the boundary of the mesh to find the start point for the bridge; it will be displayed in yellow. Click on the boundary to select the start point, and then move the mouse to where you want the bridge to end.

Click again to create the mesh bridge.

ℹ️ Note

Once you have an enclosed boundary, you can use the "Fill Holes" feature to fill gaps.

Fill Holes in Data

How to Fill Holes in Data

You can use "Fill Holes" to fill in the data holes left from scanning or any sparse areas.

Maximum Perimeter of a Hole (mm): Set the maximum size of holes (mm) to fill. Note that any holes exceeding the size you set will not be filled.

Use Neighboring Colors for Filled Holes: When the “Use Neighboring Colors for Filled Holes” is turned on, the program will use the colors around the holes for filling. Otherwise, the filled areas will be grey.

Click “Apply” to apply the changes and see the result.

Sculpt Data

How to Sculpt Data

Boolean

How to Perform Boolean Operations

There are 3 boolean operations provided: Union, Cut and Intersection.

Before performing boolean operations, you can move and rotate the data using your mouse.

• Click and hold the mouse wheel to move the data around.
• Right-click to rotate the data.

Union

Combine two or more meshes into one.

Click on the “Union” icon to open the dialogue window.

The “Assign Data” dialogue window will pop up. Select two or more data to combine together.

Click "Confirm" to combine the data. Once the data is successfully combined, you will see a new mesh file, "United Mesh" created in the Data Tree. Use the Data Tree to easily view and hide data.

Union Example

You can use the "Union" feature to attach support bars to the model. The model below was designed using Medit Model Builder. Import this data from Medit Link, then open in Medit Design. Import the support bar from your PC by clicking "Import Local Files.”

Go to Edit Mode and click "Boolean." Arrange the support bars accordingly.

Then, click "Union" to combine the models together. Combine the maxilla data with the support data to create a new, united mesh model. Repeat the same for the mandible.

Click "Complete" to finish and select how you'd like to save your data.

Intersection

Extract the intersecting mesh data.

Click on the “Intersection” icon to open the dialogue window.

The "Assign Data" dialogue window will pop up. Assign the data to A and B using the arrows. You can also drag and drop the data to A and B.

If you have assigned them incorrectly, you can simply swap the data by clicking "Swap A and B.”

Click "Confirm" and wait for the creation of a new data file. You can see that the intersecting mesh data has been extracted.

Cut

Remove mesh from A that overlaps with B.

Click on the “Cut” icon to open the dialogue window.

The "Assign Data" dialogue window will pop up. Assign the data to A and B using the arrows. You can also drag and drop the data to A and B.

If you have assigned them incorrectly, you can simply swap the data by clicking "Swap A and B.”

Click "Confirm" and wait for the creation of a new data file. You can see the mesh from A that overlaps with B has been removed, removing the occlusion data.

Cut Example

You can use the "Cut" feature to create holes in a custom tray. The model below was designed using Medit Model Builder. Import this data from Medit Link, then open in Medit Design. Import the support bar from your PC by clicking "Import Local Files.”

Import cylinder files and duplicate them to suit your needs.

Combine the six cylinders to one set using "Union." Duplicate the sets three times to create three sets of six cylinders. Place the cylinder sets are as follows and use the "Cut" function to create holes. Assign the cylinder sets to B so they can be removed from A (A-B).

Click "Confirm" to see the final result.

Duplicate

How to Duplicate Data

Use the selection tools provided to select the area you want to duplicate.

Click “Apply”, the duplicated meshes will be created. Go to the Data Tree and unselect the other data to examine only the duplicated mesh data.

You can see that the area duplicated is a new data file titles “maxillary-duplicated” in the Data Tree.

Blockout Undercut

How to Use Blockout Undercut

Click on the “Blockout Undercut” icon to open the dialogue window.

Select the data you want to fill the undercut for and click “Confirm”.

We highly recommend adjusting the data to a palatal view so you can see all the teeth. Once you’ve adjusted the position, you can use “Set Arrow to Your Viewpoint” so the blue arrow directly faces you.

Adjust and move the arrow so all undercuts can be filled as evenly as possible.

Set the angle using the slider or enter a specific number manually. Click “Apply” to apply the changes made.

Blockout undercut mesh created

Smooth Surface

How to Smooth Surface

Use the selection tools to select the surface you want to smooth.

After you’ve selected the area, adjust the smoothness strength using the slider below.

Once you are ready to see your results, click “Apply.”

You can see that the selected area is now smoother. Click "Clear All Selection" to get rid of the blue selection marks.

Mirroring

How to Mirror Data

This feature creates a symmetrical copy of your data by mirroring the mesh across the plane.

Click on the “Mirroring” icon and select your target data in the “Select Data” window. You can choose more than one data.

Selected data will appear on the screen together with the mirroring plane. The mirrored part of the data is displayed in blue.

Click “Change Direction” to change the mirroring direction from right to left.

Use the 3D Manipulator or your mouse to move the mirroring plane and control what data part is mirrored and how it is positioned on the reference data (if the latter is used).

After adjusting the mirroring plane, click “Apply.” The original data will be cut and merged with the mirrored part to create a new mesh in the Data Tree. The new data will have ‘mirrored’ added to its original name. Go to Data Tree and hide the other mesh to examine only the new mirrored data.

By default, the merging option is activated when you enter mirroring. If you don’t want to merge mirrored data with the original, click on the “Merging Option” icon once to turn it off.

With the "Merging Option" off, there will be no cutting or merging. Instead, a full symmetrical copy will be created as the new mesh. To see the difference between the "Merging Option" on and off, compare the blue mirrored parts with the source data in the picture below.

<Mirroring example with the “Merging Option” on and off before changes are applied.>

Combine

How to Combine Data

Use the “Combine” feature to join two meshes into one without making any structural changes to the original data.

Go to Transformation Mode and position your data using the 3D Manipulator. Move and rotate data to place it in the desired position before combining.

When done, return to Edit Mode and click on the “Combine” icon. In the opened dialog window, select what data will be combined and click “Confirm.”

The data is combined automatically, considering its current positioning, and a new mesh is created in the Data Tree. Hide the original data in the tree to examine only the combined mesh.

ℹ️ Note

Compared to the union option of the “Boolean” feature, combining doesn’t remove the intersecting parts of the mesh. "Combine" preserves the shape and form of the original mesh, allowing further separation of the combined files without losing mesh.

Mesh Resolution

How to Use Mesh Resolution

Each of your meshes consists of triangles. In the Edit Mode, using the “Mesh Resolution” feature, you can control the number of these triangles.

Click on the “Mesh Resolution” icon at the bottom of the screen, and select your target data in the pop-up window.

Use the “Mesh Resolution” slider to control the number of triangles that constitute the mesh. You can increase the resolution to have more sharp details in your data or lower it to have a lighter file for further rendering and converting. Click “Apply” to save changes and see the result.
