Abstract

A method and apparatus for generating a orthodontic template that assists in the placement of an orthodontic apparatus includes processing that begins by obtaining a digital model of an orthodontic structure of an orthodontic patient. The processing continues by obtaining a selection of one of a plurality of orthodontic apparatuses for the orthodontic structure to produce a selected orthodontic apparatus. The processing then continues by obtaining a digital model of placement of the selected orthodontic apparatus on the digital model of the orthodontic structure. The processing then continues by retrieving a digital image of a tooth mounting apparatus (e.g., a bracket, a band, a headgear tube, etc.) of the selected apparatus for a given tooth. The processing then continues by generating a orthodontic template for holding a physical embodiment of the tooth mounting apparatus based on the digital image of the tooth mounting apparatus, the digital model of the placement, and at least a portion of the digital model of the orthodontic structure.
