Method for producing a denture base semi-finished product

Abstract

The invention relates to a method for producing a denture base semi-finished product with the following steps: 1) Recording and digitalizing the oral cavity situation of a patient, wherein a digital three-dimensional oral cavity model of the patient is produced, or providing a digital three-dimensional oral cavity model of the oral cavity situation of a patient; 2) Implementing a first calculation in which a digital three-dimensional first model (A) of a denture base is calculated, wherein the oral cavity model of the oral cavity situation is used as a basis for the first calculation; 3) Conducting a second calculation, in which a digital three-dimensional second model (B) of a denture base semi-finished product is calculated from the first model (A) of the denture base, wherein volume is added at least in sections to the three-dimensional model (A) of the denture base; and 4) Producing the denture base semi-finished product with a Rapid Prototyping method, wherein with the Rapid Prototyping method, a CAM method is used and the digital three-dimensional second model (B) of the denture semi-finished product is used as the basis for the CAM method. The invention also relates to a device for implementing such a method and a denture base semi-finished product produced using such a method.
