Patent Images

1. 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.
