OptiDisc Research
3-Step OptiDisc™ System vs. 4-Step 3M Sof-Lex™ XT
OptiDisc achieves a higher surface polish in just three steps compared with other fourstep
systems. The charts above demonstrate that the Coarse/Medium OptiDisc has higher
mass revoval properties than the Coarse Sof-Lex XT, yet inflicts less surface roughness on
a restoration, resulting in an easier-to-achieve, smoother final polish.
