Abstract
Abstract A method and apparatus for producing a three-dimensional digital model of an orthodontic patient include processing that begins by obtaining data of an orthodontic structure of the orthodontic patient. The processing then continues by obtaining at least one scaling reference point of the orthodontic structure. The processing continues by scaling the data of the orthodontic structure based on the at least one scaling reference point to produce scaled data. The process then continues by obtaining at least two orientation reference points relating to the orthodontic structure. The processing then continues by mapping the scaled data to a coordinate system based on the at least two orientation reference points to produce the three-dimensional digital model of the orthodontic patient.
