The OptiDisc finishing and polishing system gives your restorations a final polish equal to that of natural dentition. With a three-grit system instead of the traditional four, you can achieve a higher surface gloss with fewer steps than with competitive products. OptiDiscs are translucent for enhanced working surface visibility. Kerr also offers OptiDisc Extra-Coarse for contouring composite restorative materials prior to finishing and polishing.
