Claim 10:
11. The method of claim 1, wherein processing the 3-D digital mesh and automatically detecting the one or more initial bracket positions from the acquired mesh for modifying the 3-D digital mesh to generate the digital mesh dentition model comprises coarse bracket detection by:
(i) computing a parabola along a dental arch according to the 3-D digital mesh;
(ii) detecting a tooth surface on a buccal side or a lingual side of the dental arch;
(iii) detecting a length of a normal extended toward the mesh surface from the arch on the buccal or lingual side; and
(iv) selecting points on the 3-D digital mesh that lie near the detected normal.
