16.1 Automatic Tooth Segmentation

Using the Segmentation functionality, you can also use "Automatic Tooth Segmentation". Two options are available – Select Tooth and Create STL Surfaces for All Teeth. To work with one tooth segmentation at a time, click on the Select Tooth button (1) and choose a tooth from one of the orthogonal slices (2) you need to select. The result of the selection will be colored in all the slices. A preview of the selected tooth can be shown in 3D by clicking on Show Segmentation 3D Preview (3). Tooth selection can be removed from the orthogonal slices by clicking on Clear Segmentation Data.

Tooth selection can be corrected with the "Refinement Tools" (4). It is also possible to apply a "Smooth" filter on the segmentation data. "Inflate" inflates data by one voxel while "Deflate" shrinks data by one voxel. To create a 3D model from the segmentation data, click on "Create Surface" (5). To create a new CT surface with the current segment cut out, click on "Cut from CT Surface".

If you want to run fully automated segmentation, click on "Create STL Surfaces for All Teeth" (6).
