Abstract: Disclosed is a method of obtaining the shape of a crown region for manufacturing a crown prosthesis by using an intraoral scanner having a tomographic imaging function. The method of obtaining the shape of a crown region comprises the steps of: obtaining a three-dimensional surface shape image of an oral structure including a tooth on which tooth deletion has been performed; setting a surface edge of a tooth deletion region as a location of a region of interest (52); scanning a surface shape and an internal cross-section of the oral structure at a predetermined location of the oral structure, and obtaining a partial surface shape image and a partial internal cross-sectional image of the oral structure; detecting a location of a crown margin (56) corresponding to an edge of a region where a tooth was actually deleted from the partial internal cross-sectional image; merging the location of the crown margin (56) with a surface image of a tooth (50), and causing a margin of the tooth deletion region obtained from a surface shape image of the tooth (50) to extend to the location of the crown margin (56).

Abstract: Disclosed is a computer-implemented method of designing a number of dental restorations for a patient, wherein the method includes: selecting a composed set of teeth including a number of teeth, where the number of teeth are arranged spatially relative to each other forming a high aesthetic composition; applying the composed set of teeth to a virtual three dimensional representation of the patient's present oral situation to obtain an initial set of teeth; optionally modifying one or more parameters of one or more of the teeth in the initial set of teeth to obtain a finalized set of teeth.

Abstract: The present invention relates to a process for the preparation of a sterilized ceramic body comprising or essentially consisting of stabilized zirconia of a defined colour. The process comprising the subsequent steps of a) providing a ceramic primary body comprising or essentially consisting of stabilized zirconia of a first colour A, and b) sterilizing the primary body using radiation sterilization whereby the primary body undergoes a colour change to a colour B. According to the invention, the process comprises the further step of c) irradiating the sterilized primary body with electromagnetic radiation of at least one wavelength lying in the wavelength band ranging from 150 nm to 700 nm to induce an at least partial reversal of the colour change of step b) to obtain a colour C of the sterilized ceramic body, said colour C complying with the following requirements in the CIELAB colour space : L* being from 54 to 95, a* being from -15 to 15 and b* being from -15 to 15.

Abstract: The invention relates to a method for the preparation of a blank of a ceramic material, wherein a first ceramic material and then a second ceramic material of different compositions are filled into a die and wherein the materials are pressed and after pressing are sintered. A layer of the first ceramic material is thereby filled into the die and a first cavity formed in the layer, the second ceramic material is then filled into the first open cavity and the materials pressed together and then heat-treated.
