Figure 19 shows a basal view of the finished denture; and Figure 20, the inserted work. _Process control The introduction of CAD/CAM-fabricated struc- tures (bars, bridge framework) does not change the cooperation between dentists or oral surgeons and dental technicians. However, producing the superstructure industrially necessitates rethinking thedentallaboratoryinonerespect.Theframework is no longer waxed up, but conceived on screen or, as in our case, processed on the dental labora- tory PC according to a proposal from the CAD/CAM centre and, if required, modified to fit individual wishes. External production requires appropriate scheduling. Steps determining aesthetics and function, such as approving framework design and producing the superstructure, remain in the dental laboratory as it used to be with the conventional procedure. As before, the treatment team controls the entire process. The DENTSPLY CAD/CAM centre is merely an external supplier and has no influence on the therapy. The manufacturer’s warranty on CAD/CAM structures is also of interest since it is for up to ten years. This is possible because industrial standardi- sation ensures the high quality of the blanks’ mate- rial and industrial milling guarantees maximum precision. Thus, the risk of material failure or faulty manufacturing, and hence economically difficult re-manufacture, is minimised. _Conclusion The patient was enthusiastic about her new denture. Her wishes for improved function and phonetics were fully met. The procedure described here, developed in “conventional times” according toourexperience,hasapermanentplaceinourteam.
