Abstract
Disclosed is a method of designing a dental restoration for a patient, wherein the method includes providing one or more 2D images, where at least one 2D image includes at least one facial feature; providing a 3D virtual model of at least part of the patient's oral cavity; arranging at least one of the one or more 2D images relative to the 3D virtual model in a virtual 3D space such that the 2D image and the 3D virtual model are aligned when viewed from a viewpoint, whereby the 3D virtual model and the 2D image are both visualized in the 3D space; and modeling a restoration on the 3D virtual model, where the restoration is designed to fit the facial feature of the at least one 2D image.
Claims30
A computer-implemented method of designing a dental restoration for a patient, wherein the method comprises:
- using a hardware processor to:
- provide one or more 2D images, where at least one of the one or more 2D images comprises at least one facial feature, wherein the at least one facial feature comprises lips,
- either virtually cut at least a part of teeth out of the at least one 2D image or render a part of the at least one 2D image that includes teeth at least partly or wholly transparent;
- provide a 3D virtual model of at least part of an oral cavity of the patient;
- arrange the at least one 2D image relative to the 3D virtual model in a virtual 3D space such that the at least one 2D image and the 3D virtual model are aligned when viewed from a viewpoint and remain separate representations after being arranged, whereby the 3D virtual model and the at least one 2D image are both visualized in the 3D space;
- and
- design a restoration for the 3D virtual model, where the restoration is designed to fit the at least one facial feature of the at least one 2D image;
- wherein the at least one 2D image and the 3D virtual model are aligned by scaling, translating or rotating the at least one 2D image or the 3D virtual model relative to each other.
A system for designing a dental restoration for a patient, wherein the system comprises:
- a hardware processor configured to:
- provide one or more 2D images, where at least one of the one or more 2D images comprises at least one facial feature, wherein the at least one facial feature comprises lips;
- either virtually cut at least a part of teeth out of the at least one 2D image or render a part of the at least one 2D image that includes teeth at least partly or wholly transparent;
- provide a 3D virtual model of at least part of an oral cavity of the patient;
- arrange the at least one 2D image relative to the 3D virtual model in a virtual 3D space wherein the at least one 2D image and the 3D virtual model are aligned when viewed from a viewpoint and remain separate representations after being arranged, and wherein the 3D virtual model and the at least one 2D image are both visualized in the 3D space;
- and
- design a restoration for the 3D virtual model, where the restoration fits the facial feature of the at least one 2D image;
- wherein the at least one 2D image and the 3D virtual model are aligned by scaling, translating or rotating the at least one 2D image or the 3D virtual model relative to each other.
