Abstract: Disclosed in a method, a user interface and a system for use in determining shade of a patient's tooth, wherein a digital 3D representation including shape data and texture data for the tooth is obtained. A tooth shade value for at least one point on the tooth is determined based on the texture data of the corresponding point of the digital 3D representation and on known texture values of one or more reference tooth shade values.

Abstract: A method for visualizing a 3D dental restoration on a 2D image of the mouth of a patient includes obtaining a 3D dental model of at least a part of the patient's oral cavity, designing the 3D dental restoration, obtaining the 2D image of the mouth of the patient, estimating a virtual camera including at least one virtual camera property corresponding to at least one physical camera property of the physical camera used to obtain the 2D image, viewing the 3D dental restoration using the virtual camera, determining the visible area of the 3D dental restoration, which is not overlapped by surrounding anatomic features when viewed with the virtual camera, imaging the visible area of the 3D dental restoration with the 2D image. This advantageously provides an image which with high accuracy gives the dentist and the patient a visual presentation of the final result of a dental treatment.
