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 computer product for generating a digital 3D model for use in a dental component based on a digital 3D model of the dental component showing a shape of the teeth and a digital 3D representation of a pre-prepared set of teeth showing the region for which the dental component is intended, the product causing a system to generate a digital 3D combined model representing a target dental situation when the dental component is arranged at the teeth, where the instructions are configured for digitally replacing one or more teeth of the digital 3D representation of the pre-prepared set of teeth with the digital 3D model of the dental component by digitally removing the one or more teeth of the digital 3D representation of the pre-prepared set of teeth and adding the digital 3D model of the dental component to the digital 3D representation of the pre-prepared set of teeth.

Abstract: Disclosed is a method for manufacturing a denture including a denture base and at least two artificial teeth arranged in the denture base, wherein the method includes the steps of obtaining the denture base; manufacturing the at least two artificial teeth with a common placement support connected to the at least two artificial teeth for keeping the at least two artificial teeth in a desired relative arrangement, arranging the at least two artificial teeth on the denture base with the common placement support connected to the at least artificial teeth, attaching the at least two artificial teeth on the denture base, and removing the common placement support. This further ensures proper placement of the artificial teeth in the denture base of a denture.

Abstract: Detecting a movable object in a location includes providing a first 3D representation of at least part of a surface; providing a second 3D representation of at least part of the surface; determining for the first 3D representation a first excluded volume in space where no surface can be present; determining for the second 3D representation a second excluded volume in space where no surface can be present; if a portion of the surface in the first 3D representation is located in space in the second excluded volume, the portion of the surface in the first 3D representation is disregarded in the generation of the virtual 3D model, and/or if a portion of the surface in the second 3D representation is located in space in the first excluded volume, the portion of the surface in the second 3D representation is disregarded in the generation of the virtual 3D model.
