Method of evaluating an orthodontic appliance

Abstract

A system for evaluating an orthodontic appliance. A mobile telephone for, at an 'appliance' instant, acquisition of at least one two-dimensional image (“appliance image”) of teeth at least partially representing the appliance in a service position worn by the teeth, and, at a “dentition” instant, acquisition of at least one two-dimensional image (“dentition image”) of the teeth. A computer programmed to execute, for each of a plurality of teeth represented on the at least one dentition and appliance images, the following: determination of dental and appliance attributes relative to the shape of a tooth represented on the at least one dentition image and relative to the shape of the orthodontic appliance on the at least one appliance image, respectively, and comparison of the dental and appliance attributes, followed by determination of at least a decision or at least one score according to the comparison.
