摘要

在一项临床研究中，研究了82个用procera系统制作的冠(重复铣削/火花侵蚀)的配合精度。平均边际空间宽度为71微米。发现侵蚀表面的粗糙度与粗磨金属的粗糙度相似。在侵蚀区下方，出现了硬度增加的区域，宽度约为20微米。

[Fixed tooth replacement of milled/spark eroded titanium].

In a clinical study the accuracy of fit of 82 crowns manufactured with the Procera-system (duplication milling/spark erosion) was investigated. The average marginal space width was 71 microns. Roughness of eroded surfaces was found to be similar to that of coarsely ground metal. Below the eroded areas a zone of increased hardness with a width of approximately 20 microns was demonstrated.
