The invention relates to a method for producing a dental prosthesis-base semi-finished product (6), comprising the following steps: 1) sensing and digitalizing the oral cavity situation of a patient (1), wherein a digital three-dimensional oral cavity model of the patient (1) is produced, or providing a digital three-dimensional oral cavity model of the oral cavity situation of a patient (1); 2) performing a first calculation, in which a digital three-dimensional first model (A) of a prosthesis base is calculated, wherein the oral cavity model of the oral cavity situation is used as the basis of the first calculation; 3) performing a second calculation, in which a digital three-dimensional second model (B) of a prosthesis-base semi-finished product is calculated from the first model (A) of the prosthesis base, wherein volume is added to the three-dimensional model (A) of the prosthesis base at least in some areas; and 4) producing the dental prosthesis-base semi-finished product (6) by means of a rapid prototyping method, wherein, in the rapid prototyping method, a CAM method is used and the digital three-dimensional second model (B) of the prosthesis-base semi-finished product is used as the basis of the CAM method. The invention further relates to a device for implementing such a method and to a prosthesis-base semi-finished product produced by means of such a method. |
