We performed scanning electron microscopic(SEM)observation of ceramic implant materials after cutting and polishing, and the diamond points after cutting. Also, we measured surface roughness of materials after cutting and polishing. Three ceramic implant materials(Zirconia, Alumina, Hydroxyapatite), core composite resin and 12% Au-Pd-Ag alloy were used in this study.
In SEM observation of ceramic implant materials after cutting and polishing, each material showed characteristic surface textures and these surface textures after polishing did not recover before cutting.
Surface roughness of each material before cutting was varied. But after cutting and polishing, the materials showed almost the same surface roughness. In SEM observation of the used diamond points,
chips were not observed on the diamond points which cutted the 12% Au-Pd-Ag alloy, Zirconia, Alumina and Hydroxyapatite, although chips were observed on the diamond point which cutted the core composite resin.
