Hey all

I’ve got the registration figured out but now I am trying to figure out how to make each tooth an individual segment/shell. After that, I need to add a point that is approximately 8mm from the CEJ and use that point to compare the difference between a reference mark and the segmented tooth.

Any help is greatly appreciated!

Hi!

You should try Total Segmentator, the task “Head:Teeth” will segment separately every tooth.
