Tested by DENTAL ADVISOR to be among the strongest flowable composite mechanically. Fracture toughness rated very high and correlates closely with a material's ability to resist chipping and fracture. Of composites tested in our laboratories, 3M™ Filtek™ Supreme Flowable Restorative had the highest final gloss, which speaks to lower surface roughness clinically. 3M™ Filtek™ Supreme Flowable Restorative has a unique tip design which reduces the instance of bubbles when dispensing. Bubbles can lead to voids in cured material
