I industry report _ CAD/CAM bar restoration 28 I implants3_2011 plastic. As patients recognise the clear aesthetic difference to their previous dentures, individual creation increases their satisfaction quite consider- ably.Thisalsohelpsthemtobetteracceptthe,asyet, relativelyhighcostsofimplantrestoration.Figure19 shows a basal view of the finished denture; and Fig- ure 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 super- structure industrially necessitates rethinking the dentallaboratoryinonerespect.Theframeworkisno longer waxed up, but conceived on screen or, as in our case, processed on the dental laboratory PC ac- cording to a proposal from the Compartis and, if re- quired, 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.Compartisismerelyanexternalsupplierand hasnoinfluenceonthetherapy.Themanufacturer’s warranty on CAD/CAM structures is also of interest since it is for up to ten years. This is possible because industrial standardisation ensures the high quality of the blanks’ material and industrial milling guar- anteesmaximumprecision.Thus,theriskofmaterial failureorfaultymanufacturing,andhenceeconom- ically difficult re-manufacture, is minimised. _Conclusion The patient was enthusiastic about her new denture.Herwishesforimprovedfunctionandphon- etics were fully met. The procedure described here, developed in “conventional times” according to our experience, has a permanent place in our team. Furthermore, with DENTSPLY CAD/CAM solutions we have a reliable system at our disposal. It substantially simplifies work procedures, increases precision and ensures full control over all working steps._ Editorial note: This article was first published in IDENTITY 2/10.Alistofreferencesisavailablefromtheauthors.
