抄録

Pure titanium has excellent biocompatibility. However, the machining of pure titanium is very difficult. Therefore, pure titanium is not widely used in dental materials. Recently, we developed Ti-Ag alloys and polyurea resin-bonded mounted silicon carbide wheels. The machining properties of Ti-Ag alloys were superior to those of pure titanium. In this study, pure titanium and Ti-Ag alloys were polished using the polyurea resin-bonded mounted wheel. Under the same polishing conditions, the Ti-Ag alloys showed lower surface roughness Ra and shorter polishing time for achieving the Ra target than pure titanium.
