Abstract
The authors conducted research to determine the grinding precision and accuracy of fit of ceramic inlays generated with the completely redesigned CEREC 2 computer-assisted design/computer-integrated manufacturing, or CAD-CIM, unit. They found that the grinding precision of the CEREC 2 unit was 2.4 times greater than that of CEREC 1. With CEREC 2, the mean (+/-standard deviation) luting interfaces were 56 +/- 27 micrometers, which is a 30 percent improvement in the accuracy of fit compared with that of CEREC 1.
