Claim 16:
17. An apparatus configured to generate a digital model of dentition, said apparatus comprising:
imaging apparatus for obtaining a 3-D digital mesh of dentition including braces, teeth, and gingival tissue;
processing logic for modifying the 3-D digital mesh by removing wire portions of the braces therefrom;
processing logic for modifying the 3-D digital mesh by removing bracket portions of the braces therefrom, wherein the processing logic uses normals extended from a curve generated according to a dental arch;
means for reconstructing teeth surfaces of the modified 3-D digital mesh previously covered by the wire portions and the bracket portions of the braces; and
a control logic processor programmed with instructions for displaying, storing, or transmitting over a network to another computer, the reconstructed 3-D digital mesh as the digital mesh dentition model.
