Abstract

A method may include generating a comparison of one or more anatomical reference shapes and one or more surface features on a planned dentition model with a corresponding one or more anatomical reference shapes and one or more surface features on a tracking dentition model using a coarse to fine volume 3D array to represent one or both of the plan model and the tracking model to minimize distances between teeth represented in the plan model and corresponding teeth represented in the tracking model. The method may also include detecting one or more positional differences between the anatomical reference shapes and surface features of the plan model and the corresponding anatomical reference shapes and surface features of the tracking model based on the comparison and generating a modified treatment plan based on the one or more detected positional differences.
