A method for producing a partial dental prosthesis, the partial dental prosthesis comprising at least one prosthetic tooth, a prosthetic base, and a carrier structure the prosthetic base comprising a gum-colored plastic material and the at least one prosthetic tooth, the prosthetic base, and the carrier structure being securely interconnected in the method, the method comprising the following steps:
- A) digitally constructing a virtual three-dimensional model of the partial dental prosthesis with or without the carrier structure or applying an existing virtual three-dimensional model of the partial dental prosthesis with or without the carrier structure
- B1) generating a virtual three-dimensional model of the at least one prosthetic tooth (2), a virtual three-dimensional model of the prosthetic base, and a virtual three-dimensional model of the carrier structure on the basis of the virtual three-dimensional model of the partial dental prosthesis with the carrier structure such that the virtual three-dimensional model of the at least one prosthetic tooth, the virtual three-dimensional model of the prosthetic base, and the virtual three-dimensional model of the carrier structure result in partial volumes of the virtual three-dimensional model of the partial dental prosthesis with the carrier structure that are separate from one another, or
- B2) generating a virtual three-dimensional model of the at least one prosthetic tooth and a virtual three-dimensional model of the prosthetic base on the basis of the virtual three-dimensional model of the partial dental prosthesis without the carrier structure such that the virtual three-dimensional model of the at least one prosthetic tooth (2) and the virtual three-dimensional model of the prosthetic base result in partial volumes of the virtual three-dimensional model of the partial dental prosthesis without the carrier structure that are separate from one another;
- C1) producing the carrier structure on the basis of the virtual three-dimensional model of the carrier structure using a CAM method or
- C2) producing the carrier structure using an analog method by adjusting to the patient or by adjusting to a physical model of the patient's oral cavity and scanning the surface of the carrier structure produced in an analog manner, and generating a virtual three-dimensional model of the carrier structure from the scan of the surface of the carrier structure produced in an analog manner, the virtual three-dimensional model of the carrier structure generated from the scan being added to the virtual three-dimensional model of the partial dental prosthesis without the carrier structure by digital processing and a virtual three-dimensional model of the partial dental prosthesis with the carrier structure thus being generated, and the virtual three-dimensional model of the carrier structure generated from the scan being subtracted in regions from the virtual three-dimensional model of the at least one prosthetic tooth by digital processing or being subtracted in regions from the virtual three-dimensional model of the at least one prosthetic tooth and in regions from the virtual three-dimensional model of the prosthetic base
- D) providing a milling body for producing the at least one prosthetic tooth, the milling body consisting of a material suitable for prosthetic teeth;
- E) producing a connecting surface between the at least one prosthetic tooth and a support structure for positioning the carrier structure on one hand and the prosthetic base and the carrier structure on the other hand in a surface of the milling body by means of a subtractive CAM method in line with the virtual three-dimensional model of the at least one prosthetic tooth, the virtual three-dimensional model of the prosthetic base and the virtual three-dimensional model of the carrier structure;
- F) after step E), arranging or fastening the carrier structure on the connecting surface of the milling body;
- G) after step F), introducing at least one fluid polymerizable plastic material onto regions of the connecting surface and into the volume removed in step E) in the surface of the milling body;
- H) after step G), curing or partially curing the at least one fluid polymerizable plastic material, a cured plastic material resulting during the curing or a partially polymerized plastic material resulting during the partial curing, the cured plastic material or the partially polymerized plastic material interconnecting the carrier structure and the material of the milling body;
- and
- I) after step H), subtractively machining the cured or partially polymerized plastic material and the milling body using a CAM method in line with the virtual model of an outer surface of the partial dental prosthesis, such that the partial dental prosthesis comprising the carrier structure, the cured or partially polymerized plastic material, and the material of the milling body is subtractively worked out.
