Removal of Invisalign resin retention buttons without damaging underlying enamel is a major challenge. To date, the use of tungsten carbide burs is the most common and fastest--yet a risky-ablation method. Stainbuster, a fiber-reinforced resin bur, has been introduced for removal of surface stains and resin remnants from tooth surfaces. This comparative in vitro and in vivo study proved that a combined technique, using multifluted tungsten carbide burs for fast removal of the bulk of resin followed by Stainbuster grinding for gentle removal of the final resin layer, is a safe and minimally invasive procedure for removing composite buttons from enamel.
