Abstract

See full text

A method for producing a guide rail having the steps of:

    (A) generating or providing a virtual 3D model of a dental prosthesis with at least one virtual model of a machined prosthetic tooth to be arranged in a prosthesis base;(B) calculating a volume to be removed from a prefabricated prosthetic tooth;(C) generating a virtual model of a guide rail which is fixed to a mount for fastening the prefabricated prosthetic tooth such that the guide rail enables guidance of a milling head and/or a cutting tool of known dimensions, in such a manner that the volume to be removed from the prefabricated prosthetic tooth is traversed with the milling head; and(D) producing a physical guide rail on the basis of the virtual model of the guide rail using a CAM method.
