1. Method for generating a digital model of a dental replacement part including a dental prosthesis and a prosthesis base having a rear protection plate, the method comprising the steps of: providing a digital model of a jawbone or a jawbone section having a digital dental prosthesis model positioned therein, wherein an interface is automatically and/or manually marked in a region of the dental prosthesis model, forming a rear protection plate model by the interface, an abutting surface of the digital jawbone model, and a region of a surface of the dental prosthesis model joining the surface of the digital jawbone model and the interface, forming a revised dental prosthesis model from the digital dental prosthesis model by adopting the interface as a surface, and producing the digital model of the dental replacement part from the rear protection plate model and the revised dental prosthesis model.
