Hello
I have some oral scan files in ply format and I want to automatically segment and extract all the healthy and prepared teeth and save each one in a separate ply file. Is this possible in 3D Slicer software?
If so, please explain the steps to do it.

Here is this module, not sure if it still works

We tried to find reliable alternative methods for surface segmentation and also training our own models, but this segmenting surface meshes is a difficult topic.
