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: Disclosed is a method for scanning an edentulous patent who has a denture, where an impression material arranged at the gum-facing surfaces of the dentures is shaped by the patient's gums and both the teeth side and the gum-facing surface of the denture is scanned and the obtained digital 3D representations are used to determine the relative arrangement of the patient's edentulous jaws in a bite determined by the dentures.

Abstract: A method for manufacturing a dental restoration for a patient, where the method includes: obtaining a 3D scan of at least a restoration site of the patient's mouth, where the manufactured dental restoration is adapted for fitting to the restoration site; obtaining a CAD design of the dental restoration; milling the restoration from a material, where the restoration is milled both on an inside surface configured for fitting to the shape of the restoration site of the patient's mouth and on an outside surface, where the milling is according to the obtained CAD design; transferring the milled restoration to a retention means providing a fixed known position of the restoration relative to a post-processing machinery, where the restoration is retained on the inside surface, such that the outside surface of the restoration is approachable/free/accessible; and performing post-processing of the outside surface of the restoration.

Abstract: Disclosed is a 3D scanning system and a method for using such a system, where a handheld scanner of the 3D scanner system is used to control the operation mode of the system such that the user does not need to engage an external unit e.g. during a scanning procedure in which the teeth in a patient's upper and lower jaws are scanned.

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.
