A method and apparatus for generating a three-dimensional digital model of a desired orthodontic structure include processing that begins by obtaining a three-dimensional model of an actual orthodontic structure, wherein the three-dimensional digital model is defined in x, y, z space. The processing then continues by generating an interim three-dimensional model of the desired orthodontic structure less teeth. The interim three-dimensional model is designed in x, y, z space and includes the desired placement of an occlusal plane, an upper-arch form, a lower-arch form, an upper-arch midline, and a lower- arch midline. The processing then continues by positioning the upper and lower teeth with respect to the interim digital model and the defined x, y, z space to obtain a first pass three-dimensional digital model of the desired orthodontic structure. The processing continues by determining whether achieving the first pass three-dimensional model is feasible. When achieving the first pass three-dimensional image is feasible, the processing continues by utilizing the first pass three-dimensional model as the desired three-dimensional digital model.
