[Precision of the Cerec-System: the milling unit].
The Cerec-System is a computer-assisted method for fabrication of customized ceramic inlays. Until now there are no data available to judge the precision of this system, which is a function of several variables. This study investigated the tolerance of the milling unit by using computer-constructed data sets for test purposes. REM pictures show how the diamond bur is affected by several milling cycles. Overall precision along the x- or z-axis is largely independent of the inherent properties of the milling instrument used, such as wear. Precision along the y-coordinate, however, is dependent on the number of milling cycles and the feed along the horizontal axis. Best results can be obtained by using a new bur and slow feed.
