Abstract: A method for providing a guided relative movement of a first object and a second object includes obtaining the first object; obtaining the second object and a 3D model of the second object, and deriving from the 3D model a first preferred relative arrangement between the first and second objects; obtaining a pre-process plan describing a preferred path for the relative movement of the first and second objects towards the first preferred relative arrangement; performing a movement procedure that includes 3D scanning at least a region of said second object using the 3D scanner and determining a present relative arrangement of the first and second objects from a result of the 3D scanning; calculating information for correcting in real-time for deviation in the relative movement from the preferred path; and providing a relative movement of the first and second objects towards the first preferred relative arrangement.

Abstract: A method, a user interface and a system for use in determining shade of a patient's tooth, wherein a digital 3D representation includes 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, said 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.
