Problems solved by technology
On the one hand, a great waste of material is disadvantageous, which may undoubtedly exceed 90% depending on the anatomy of the individual patient
On the other hand, this results in time-intensive machining times for CAM devices, as a lot of material has to be removed
In addition, the wear and tear of each milling cutter is quite serious
[0009] The disadvantage here is that the processing time until the denture base is produced is quite long
In addition, machining of blanks wears out the milling cutter heads and requires regular refurbishment

Embodiment Construction
[0061] In the figures, the same reference numerals are also used for parts that are the same in different exemplary embodiments.
[0062] figure 1 A schematic perspective view of the denture base blank 1 of the present invention is shown. The denture base blank 1 consists of a plastic, preferably a polymer. The denture base blank 1 has a parabolic thickening on the marginal side, which forms the prefabricated dental arch 2 . The denture base blank 1 is symmetrical with respect to the center plane. This center plane corresponds to the sagittal plane of the patient fitted with a denture produced from the denture base blank 1 . The apex 4 of the parabolic dental arch 2 is located in the center of the geometry, that is to say in the sagittal plane. When producing a complete denture or a partial denture comprising at least the central incisors from this denture base blank 1 , the vertices 4 of the denture base thus produced are then placed on the patient's lips (ie labially). ...

Abstract
The invention relates to a prosthesis-base blank (1) for producing a prosthesis base for a dental prosthesis by means of a subtractive CAM method, wherein the prosthesis-base blank (1) is composed of a plastic or a wax, wherein the prosthesis-base blank (1) is preformed and wherein a dental arch (2) or a dental-arch segment is preformed as a material thickening of the prosthesis-base blank (1). The invention further relates to a set comprising at least one such prosthesis-base blank (1). The invention further relates to a method for producing a prosthesis base for producing a total dental prosthesis or at least a partial dental prosthesis by means of a prosthesis-base blank (1) according to one of the proceeding claims, comprising the following steps: fastening the prosthesis-base blank (1) in a CAM device for removing material of the prosthesis-base blank (1) by means of a CAM method and removing material of the prosthesis-base blank (1) by means of the CAM device on the basis of a computed CAD model.
Description
technical field [0001] The invention relates to a denture base blank for manufacturing a denture base for dentures by a subtractive CAM method, wherein the denture base blank is made of plastic or wax. [0002] The invention also relates to a method for producing a denture base for artificial teeth and a kit for carrying out the method with such a denture base blank. [0003] Thus, the present invention finally relates to the manufacture of partial plastic dentures (partial dentures) and full plastic dentures (full dentures) for the dental field or its denture bases, by means of machines according to the CAM method (CAM: Computer-Aided Manufacturing (Computer-Aided Manufacturing) Manufacturing)) to make. Dentures and denture bases are preferably constructed computer-aided using CAD methods (CAD: Computer-Aided Design). In this case, the denture base is first produced and rests on the gingiva of the edentulous or partially edentulous patient's jaw arch. These dentures are th...
