Abstract
A method and apparatus for designing an orthodontic structure to provide tooth movement includes processing that begins by obtaining a three-dimensional digital model of a desired orthodontic structure. The processing continues by generating a zero force arch wire based on the three-dimensional digital model of the desired orthodontic structure. The processing continues by placing brackets on at least some of the plurality of teeth in a zero force position with respect to the zero force arch wire. Having placed the brackets on the desired orthodontic structure, the placement is transferred to a three-dimensional digital model of an actual orthodontic structure. Having transferred the bracket placement, a jig may be formed from the digital model of the actual orthodontic structure with the brackets installed. The jig holds the physical embodiments of the brackets such that the brackets may be placed in the patient's mouth in the position determined by the automated process.
