The Ceri-Saw is a hand-held, interproximal saw specially designed to remove excess composite in the contact areas, using one or both hands. The Ceri-Saw is available in two sizes: anterior (regular size) for anterior interproximal surfaces and posterior (small size) for posterior interproximal surfaces. The serrated edge of the Ceri-Saw blade is approximately .02 mm thick. The Ceri-Saw can be sterilized in an autoclave.
