The invention relates to a method for producing a wax base or a prosthesis base for producing a dental prosthesis, with which a virtual CAD model of the dental prosthesis is used for the production of the physical dental prosthesis or the physical prosthesis base, wherein, from the CAD model of the dental prosthesis, a virtual model of the prosthesis base is calculated, characterized by the following chronological steps:A) Scanning in of at least one three-dimensional region of a physical model of the oral cavity situation of a patient and preparation of a first data record on the basis of this scan, orintra-oral scan of a three-dimensional region of the oral cavity situation of the patient and production of a physical model of the oral cavity situation of a patient on the basis of the intra-oral scan and preparation of a first data record on the basis of the intra-oral scanB) application of a wax layer or a plastic layer onto the physical model of the oral cavity situationD) calculation of a virtual surface as a surface which is to be formed in the wax layer or in the plastic layer, wherein the calculation is made on the basis of the virtual model of the prosthesis base and of the first data record, and wherein positioning aids are provided in the surface which is to be produced, for the positioning of prosthetic teeth andE) production of the wax base from the wax layer or of the prosthesis base from the plastic layer with a subtractive CAM method, on the basis of the virtual surface calculated in step D).The invention also relates to a method for producing a dental prosthesis or a wax set-up for a dental prosthesis, and a prosthesis base, a wax base, or a dental prosthesis, produced with such a method.
