US 11,020,205 B2 · Providing a simulated outcome of dental treatment on a patient

Abstract

Systems and methods of simulating dental treatments are disclosed. A method may include capturing a first 2D image of a patient's face, including the patient's teeth, building a parametric 3D model of the patient's teeth based on the 2D image, developing a simulated outcome of a dental treatment of the patient's teeth by rendering the 3D model with the patient's teeth in one or more positions and/or orientations corresponding to the treatment goals of the dental treatment plan, and rendering a second 2D image of the patient's face with teeth according to a simulated outcome of the dental treatment plan. As noted herein, the dental treatment plan may include orthodontic and/or restorative elements. The simulated outcome may correspond to estimated outcomes and/or intended outcomes of the dental treatment plan.

Dependent claims

A computer-implemented method of simulating orthodontic treatment, the method comprising:

capturing a first 2D image, the first 2D image comprising a representation of a patient's face and a patient's teeth of a patient;
identifying one or more shapes associated with at least one of the patient's teeth;
building a parametric 3D model of the patient's teeth based on the 2D image, using one or more case-specific parameters for the one or more shapes associated with the at least one of the patient's teeth;
simulating an outcome of a dental treatment plan for the patient's teeth to produce a simulated outcome of the dental treatment plan;
modifying the parametric 3D model to provide a modified 3D model representing the simulated outcome of the dental treatment plan;
and
rendering, using the modified 3D model, a second 2D image representing the patient's face, the second 2D image representing the patient's teeth in accordance with the simulated outcome of the dental treatment plan.

4 more elements

A computer-implemented method of building a 3D model of teeth from a 2D image, the method comprising:

capturing a 2D image of a patient's face, including their teeth;
determining edges of teeth and gingiva within the first 2D image;
fitting the teeth in a 3D parametric model of teeth to the edges of the teeth and gingiva within the first 2D image, the 3D parametric model including case-specific parameters for the shape of the patient's teeth;
and
determining the value of the case-specific parameters of the 3D parametric model based on the fitting.
