ORTHODONTIC PROGRESS TRACKING USING COARSE TO FINE 3D MODELS
Abstract: a method may include obtaining a plan model of a patient's teeth, obtaining a tracking model of the patient's teeth representing an arrangement at an intermediate stage of a treatment plan, generating a comparison of the plan model with the tracking model using a coarse to fine volume 3d array to represent one or both of the plan model and the tracking model, detecting one or more positional differences between anatomical reference shapes and surface features of the plan model and corresponding anatomical reference shapes and surface features of the tracking model based on the comparison and using the coarse to fine volume 3d array, generating a modified treatment plan based on the one or more detected positional differences, and fabricating a dental appliance based on the modified treatment plan.
