Devices and methods for producing denture parts
Surface mapping and/or generation device is provided, with a device for mapping 3D data of at least one denture base object such as a tooth stump or an implantation abutment, and an environment thereof, as well as with a device for the data-based generation and production of a denture part incorporating the 3D data of the denture base object. Additionally provided are a device for determining and/or defining a placement direction of the denture part that is to be slipped onto the denture base object, and a device for determining and producing a primary part that is to be slipped onto the denture base object before the denture part and that yields a desired placement direction for the denture part which is different from the placement direction that exists for slipping the primary part onto the denture base object. The device for data-based generation and production of a denture part is designed to generate and produce the latter by incorporating the 3D data of the primary part. Surface mapping and/or generation method is provided, wherein 3D data from a denture base object such as a tooth stump or an implantation abutment and an environment thereof are mapped and then, based on this 3D data of the denture base object, a denture part to be slipped thereon is produced. Before production of the denture part, a placement direction of the denture part onto the denture base object is determined or defined. On the basis of this 3D data of the denture base object, a primary part is determined and produced, with which a desired placement direction that differs from the placement direction that exists for slipping the primary part onto the denture base object is created for the denture part. On the basis of the 3D data, the denture part is generated and produced based on data so as to fit when pushed onto the primary part.
