摘要:
The invention relates to a method for producing a dental prosthesis having the following chronological method steps:a) a first, provisional dental prosthesis comprising at least one first prosthetic base (1) and several provisional prosthetic teeth (4) is produced, whereby data that indicate at least the 3-dimensional form of the occlusal surfaces (6) of the provisional prosthetic teeth (4) of the provisional dental prosthesis are stored as data record A or have already been stored as data record Ab) after subtractive occlusal processing of at least one of the provisional prosthetic teeth (4), at least the 3-dimensional occlusal surfaces (6) of the processed provisional prosthetic teeth (4) of the first dental prosthesis are determined, or the 3-dimensional surface of the first dental prosthesis is determined as a wholec) data that indicate at least the 3-dimensional form of the occlusal surfaces (6) of the processed provisional prosthetic teeth (4) are stored as data record Bd) via a computer comparison of data record B with data record A, the differences in the forms of the provisional prosthetic teeth (4) before and after the subtractive occlusal processing are calculated and, from this, at least desired lengths for final prosthetic teeth (20) are calculated, ande) final prosthetic teeth (20) are produced at least with the calculated desired length using a CAM method from virtual models of the final prosthetic teeth (20), whereby the desired length of the final prosthetic teeth (20) is set by a basal shortening of the virtual models of the final prosthetic teeth (20), and the final prosthetic teeth (20) produced in such a manner are firmly connected to the at least one first prosthetic base (1) or at least one second prosthetic base.The invention further relates to a dental prosthesis produced with such a method.
