抄録

This study was conducted to improve the efficiency of the polishing procedure for various prosthetic appliances by using a newly-developed centrifugal shooting type polishing system.<BR>This apparatus has a specific structure for shooting the polishing particles using centrifugal force. The polishing particles consist of an elastic body as a core and layer of polishing material adhering to that core. The apparatus does not bounce off the polishing surface but slides along it.<BR>Two kinds of denture base materials (Co-Cr alloy and denture base resin) were investigated in this study. Polishing for each sample was performed at five different shooting angles of the polishing particles and in five different polishing times, respectively. The surface texture of these samples was investigated with a surface texture measuring apparatus. The results were as follows:<BR>1. Satisfactory surface roughness was obtained when the shooting angle was less than 45°.<BR>2. It took 3 to 10 minutes for Co-Cr samples and 1/2 to 3 minutes for resin samples to improve surface roughness.<BR>3. It was suggested that the surface of various dental materials could be polished using the same polishing particles by converting the shooting velocity of particles.
