Abstract: A method for color customization of dental restorations is presented with the steps of providing tooth measurement data, wherein the tooth measurement data comprise at least one insertion area in which the dental restoration is to be inserted, providing restoration data, providing information about staining or glazing colors, generating a color characteristic from the tooth measurement data taking into account the restoration data, and calculating a multicolor target coloration from the color characteristic taking into account the information on staining or glazing colors, as well as output of the multicolor target coloration for color customization of the dental restoration.

Abstract: A method and system for dynamically providing visual feedback about a quality of data collected during intra-oral scanning Images or light patterns are projected onto an object such as teeth for 3D measurement and for relaying feedback about a quality of the 3D measurement to a user. In this way unsuccessful registrations surface areas of the teeth that have not been acquired yet may be corrected by informing the user to repeat scans at corresponding locations in the intra-oral cavity.

Abstract: The invention relates to a method (100) and to a corresponding system (1) for providing a dental prosthesis (10) made from ceramic material (2) having a colour matched to the patient comprising the following steps:—receiving (110) a desired nominal colour for the dental prosthesis (10), determining (120) a deviation between the nominal colour and actual colour of the sintered ceramic material (2) by the control unit (4) and defining (130) a temperature time cycle havoing a cycle time (TH), suitable for compensation of the deviation, for sintering at a defined sintering temperature (TS) and creating a corresponding sintering program (5) by the control unit (4); and—adjusting (140) the actual colour of the selected ceramic material (2) to the nominal colour (4) in the sintering furnace (3) by the sintering program (5) executed by the sintering furnace (3).
