The optical fine scanner RM 600 Laser Stylus (Rodenstock) allows in combination with the perthometer S 8P (mechanical scanner, Feinprüf/Perthen) a direct quantitative analysis of elastic impression materials. We verified with this apparatus the accuracy of surface reproduction of thirty-three various impression materials. The mean roughness values (Rz) of the originals and the reproductions showed no significant differences. This result suggests that all materials used have a high surface reproduction and they can be used unrestrictly.
光学精密扫描仪RM 600激光触针式表面粗糙度仪（罗敦司得公司）与表面光洁度仪S 8P（机械扫描仪，Feinprüf/Perthen公司）相结合，可对弹性印模材料进行直接定量分析。我们用该仪器验证了33种不同印模材料表面复制的准确性。原件和复制品的平均粗糙度值（Rz）没有显著差异。这一结果表明，所有使用的材料都具有较高的表面复制性，可无限制地使用。
