Abstract: Disclosed is a method for compensating for motion blur when performing a 3D scanning of at least a part of an object by means of a 3D scanner, where the motion blur occurs because the scanner and the object are moved relative to each other while the scanning is performed, and where the motion blur compensation comprises: —determining whether there is a relative motion between the scanner and the object during the acquisition of the sequence of focus plane images; —if a relative motion is determined, performing a motion compensation based on the determined motion; and —generating a 3D surface from the sequence of focus plane images.

Abstract: Disclosed is a method, a system, and a user interface for determining a preferred relative arrangement of digital restoration designs and digital representations of multi-shaded milling blocks for use when manufacturing dental restorations from multi-shaded milling blocks. A preferred first relative arrangement of a first digital restoration design and a digital representation of a first multi-shaded milling block is determined, and therefrom a preferred second relative arrangement of a second digital restoration design and a digital representation of a second multi-shaded milling block is determined.

Abstract: A method for creating a digital model of a denture for a patient, where the denture includes a gingival part and artificial teeth, includes obtaining digital models of artificial teeth representing the artificial teeth; obtaining a 3D scan comprising a digital representation of at least part of the patient's existing gingiva; digitally modeling a gingival part of the digital model of the denture using the 3D scan and the digital artificial teeth; digitally determining a first offset defining a first thickness of a first portion of the gingival part of the digital model of the denture that extends from the digital representation of the at least part of the patient's existing gingiva; and digitally determining a second offset defining a second thickness of a second portion of the gingival part of the digital model of the denture that extends from the digital artificial teeth.
