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.
作者开展了研究，以确定使用完全重新设计的CEREC 2计算机辅助设计/计算机集成制造（CAD-CIM）设备生成的陶瓷嵌体的研磨精度和适配精度。他们发现，CEREC 2设备的研磨精度比CEREC 1高2.4倍。使用CEREC 2时，平均（±标准差）粘接界面为56±27微米，与CEREC 1相比，适配精度提高了30%。
