Abstract

An automated method for generating a final setup for orthodontic treatment. The method includes receiving a digital 3D model of teeth in an initial state. The method computes a scoring function based upon metrics related to the initial state to generate a corresponding score, perturbs the state of the teeth through translations and rotations of a tooth or set of teeth to generate a perturbed state of the teeth, and updates the state of the teeth based upon the score and the perturbed state of the teeth to generate one or more final setups representing a final state of the teeth after the orthodontic treatment.

Claims23

Dependent claims

A computer-implemented method for generating one or more final setups for orthodontic treatment, comprising steps of:

receiving a digital 3D model of teeth in an initial state;
computing a scoring function based upon metrics related to the initial state to generate a corresponding score;
perturbing a state of the teeth through movement of a tooth or set of teeth within the digital 3D model of teeth to generate a perturbed state of the teeth;
and
updating the state of the teeth based upon the score and the perturbed state of the teeth to generate one or more final setups representing a final state of the teeth after the orthodontic treatment.
