[Filling composites. Experimental study of surface finishing by abrasion]

Dealing with composite resins, our work is an account of personal researches on the methods and means of polishing. We have tested four rotary abrasive instruments on two composite resins: diamond burs, white Arkansas stones, silicon-carbide polishers, flexible polyurethane-based finishing and polishing disks. The results of the obtained measures of the surface roughness have enabled us to select a limited specific instrumentation which is included in a second experimentation leading to the conception of simple finishing procedures of the composite resins.
