Claim 12:
13. A method for segmenting a 3-Dimensional (3D) model image of a patient's dentition comprising: a) obtaining a first 3D model image of the patient dentition using an intraoral scanner and generating a segmentation of the first 3D model image, wherein the segmentation provides at least a tooth surface contour and a tooth label for a plurality of teeth of the first 3D model; b) obtaining a second 3D model image of the patient dentition, the second 3D model image having a surface; c) registering each segmented tooth surface contour of the first 3D model image to the surface of the second 3D model image; d) obtaining a second segmentation of the second 3D model image according to the registered tooth surface contour, wherein the second segmentation similarly provides at least a tooth surface contour and a tooth label for a plurality of teeth of the second 3D model image; e) identifying a tooth feature for at least one tooth of the first 3D model image and identifying a corresponding tooth feature of the second 3D model image based on the identified at least one tooth feature of the first 3D model image; and f) storing the segmented second 3D model image.
