Patent ID: 6851949

Claim:
A method for generating a three-dimensional digital model of a desired orthodontic structure, the method comprises the steps of: a) obtaining a three-dimensional digital model of an actual orthodontic structure, wherein the three-dimensional digital model is defined in x, y, z space; b) generating an interim three-dimensional digital model of the desired orthodontic structure less teeth in the defined x, y, z space, wherein the interim three-dimensional digital model includes desired placement of an upper and lower occlusal plane, an upper arch form, a lower arch form, an upper arch midline, and a lower arch midline; c) positioning upper and lower teeth with respect to the interim three-dimensional digital model in the defined x, y, z space to obtain a first pass three-dimensional digital model of the desired orthodontic structure; d) determining whether achieving the first pass three-dimensional digital model is feasible; and e) when achieving the first pass three-dimensional image is feasible, utilizing the first pass three-dimensional digital model as the desired three-dimensional digital model.
