A method of fabricating a wax prosthesis, the wax prosthesis having a prosthesis base and a plurality of basally machined prefabricated denture teeth, the method being performed using a virtual three-dimensional dental prosthesis model, the method comprising the steps of: A) Dividing the virtual three-dimensional dental prosthesis model of the physical wax prosthesis to be produced into at least one virtual three-dimensional model of the denture teeth and a virtual three-dimensional model of a denture base (10, 20) or using at least one existing virtual three-dimensional model of the denture teeth and an existing virtual three-dimensional model of the denture base (10, 20), B) Producing a preformed blank of wax or of a waxy plastic material manually moldable at below 80°C with a generative first CAM device according to the data of the upper surface of the virtual three-dimensional model of the denture base (10, 20), wherein either C1) a plurality of tooth compartments are produced in the upper side of the preformed blank after the preformed blank has been produced with a subtractive second CAM device, or C2) during the production of the preformed blank with the generative first CAM device, a plurality of tooth compartments are generated in the upper side of the preformed blank, wherein one tooth compartment is generated in the blank for each prefabricated denture tooth to be inserted according to the virtual three-dimensional dental prosthesis model, D) Inserting and fixing the unprocessed prefabricated denture teeth into the respective tooth compartments of the preformed blank, E) Shortening the basal sides of the prefabricated denture teeth fixed in the preformed blank with the subtractive second CAM device or a subtractive third CAM device according to the data on the underside of the virtual three-dimensional model of the denture base (10, 20), wherein the prefabricated denture teeth are shortened to a greater extent than specified by the data for the underside of the virtual three-dimensional model of the denture base (10, 20), F) Subtractively machining the underside of the preformed blank with the subtractive second CAM device or the subtractive third CAM device or a subtractive fourth CAM device according to the data of the underside of the virtual three-dimensional model of the denture base (10, 20). A) Dividing the virtual three-dimensional dental prosthesis model of the physical wax prosthesis to be produced into at least one virtual three-dimensional model of the denture teeth and a virtual three-dimensional model of a denture base (10, 20) or using at least one existing virtual three-dimensional model of the denture teeth and an existing virtual three-dimensional model of the denture base (10, 20), B) Producing a preformed blank of wax or of a waxy plastic material manually moldable at below 80°C with a generative first CAM device according to the data of the upper surface of the virtual three-dimensional model of the denture base (10, 20), wherein either C1) a plurality of tooth compartments are produced in the upper side of the preformed blank after the preformed blank has been produced with a subtractive second CAM device, or C2) during the production of the preformed blank with the generative first CAM device, a plurality of tooth compartments are generated in the upper side of the preformed blank, wherein one tooth compartment is generated in the blank for each prefabricated denture tooth to be inserted according to the virtual three-dimensional dental prosthesis model, D) Inserting and fixing the unprocessed prefabricated denture teeth into the respective tooth compartments of the preformed blank, E) Shortening the basal sides of the prefabricated denture teeth fixed in the preformed blank with the subtractive second CAM device or a subtractive third CAM device according to the data on the underside of the virtual three-dimensional model of the denture base (10, 20), wherein the prefabricated denture teeth are shortened to a greater extent than specified by the data for the underside of the virtual three-dimensional model of the denture base (10, 20), F) Subtractively machining the underside of the preformed blank with the subtractive second CAM device or the subtractive third CAM device or a subtractive fourth CAM device according to the data of the underside of the virtual three-dimensional model of the denture base (10, 20).
