[Quantitative profilometric surface analyses to verify the accuracy of reproduction of elastic impression material].
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.
