title: The clinical performance of CAD-CAM-generated ceramic inlays: a four-year study.
abstract: The authors conducted a long-term clinical study of 50 CEREC (Siemens AG) CAD-CAM inlay restorations in 28 patients. After four years, they found the inlays to rate very highly in color matching, interfacial staining, secondary caries, anatomic contour, marginal adaptation, surface texture and postoperative sensitivity. They monitored cement loss along the occlusal margins and found it to be relatively low, with an unusual decrease in measured cement wear from the third to the fourth year. The favorable results of this long-term clinical study of these CAD-CAM restorations portend significant success for this restorative approach.
