Abstract: A 3D scanner for recording the 3D topography of an object, the 3D scanner includes an illumination unit configured for providing probe light for illuminating the object, where the probe light includes a pattern of light rays; an image sensor for acquiring one or more 2D images of light rays returning from the illuminated object; an optical system including an optical element arranged such that the patterned probe light passes through it when propagating towards the object from the illumination unit along an optical path; and a device for changing the configuration of the optical system between a first and a second configuration, where the change in configuration comprises a change in orientation of the optical element between a first orientation and a second orientation relative to the optical path of the probe light.

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.
