Abstract
A computer-implemented method for generating one or more segmented 3-D teeth models obtains a 3-D mesh model of a patient's dentition and executes a first segmentation procedure on the obtained 3-D mesh model, displaying one or more segmented teeth from the 3-D mesh model. At least one of the one or more segmented teeth is recorded according to operator instruction and removed from the 3-D mesh model to form a modified 3-D mesh model. A repeating sequence identifies a modified segmentation procedure, executes the modified segmentation procedure on the modified 3-D mesh model, displays one or more segmented teeth from the modified 3-D mesh model, records at least one of the one or more segmented teeth, and removes the recorded at least one tooth from the modified 3-D mesh model. Recorded segmentation results are displayed, stored, or transmitted.
