Discs are a color-coded, easy-to-use sequence of 4 semiflexible aluminum-oxide discs, designed to efficiently shape and refine composite restorations. Available in the 2 most popular sizes of 3/8" and 1/2" diameters that effortlessly and securely pop onto a round mandrel. Consistent flex that allows for control without gouging at the margin and minimizes any scarring of the surface. Choose the 3/8" disc for margins and areas near the papilla, as well as on posterior and/or pedodontic restorations. Larger 1/2" disc is perfect for larger surface reduction, contouring, and polishing.
