Segmentation

A quick look into how to segment your scans

Segmenting teeth

To segment your scan, click on the occlusal surface of each tooth to place a segmentation marker. If you misplace a marker, you can click on it again to remove it.

After you have selected each tooth, click Separate. Once segmentation is done, the teeth will be colored in with borders along the gingival margin.

Adjusting gingival margin

There are two tools for adjusting the boarder. Sculpting is for moving the lines and Smoothing is for smoothing them out.

Sculpting

  1. Click on the tooth.
  2. Click and drag along the border to move the curve.
  3. Click Done Editing Tooth or press the Enter key.

Smoothing

  1. Click on Smooth.
  2. Click and hold over the area you wish to smooth.
  3. Click Done Editing Tooth or press the Enter key.

If a tooth is not filled in, the software does not allow you to proceed before you have filled in that tooth. To fix, adjust the boarder until it is not crossing any adjacent gingival margins and the tooth color automatically fills in.

When finished adjusting all boarders, click ACCEPT CURVES.

Verifying segmentation

The segmentation check stage helps you review your segmentation with the model rendered in full color, as you will see it during treatment planning. You can pan around the model to verify that everything looks ok. If a boarder was misplaced or overlooked, you can go back to adjust it by clicking Back to Curves.

During the segmentation check, you have the opportunity to verify the AI tooth numbering. The software will identify which teeth are missing and apply tooth numbers. If changes to the tooth numbering are required, simply click the number on the tooth chart, in the upper-left hand corner, to X out the missing tooth and click on any Xs to remove it and mark the tooth as present. The tooth numbering system can be changed in Settings under Dental Notation.
