Ivoclar Vivadent has introduced a new and improved version of the clinically proven Tetric EvoCeram® nano-optimized composite. Improvements to this already popular composite filling material offer dentists such benefits as extended working time under ambient light combined with faster curing times, new shades with enhanced shade matching qualities and improved handling properties. As a result, Tetric EvoCeram reduces the application time necessary for completing direct composite restorations. Tetric EvoCeram resolves many issues dentists typically encounter with conventional composite materials, including their tendency to polymerize before restorations are fully contoured. A special additive incorporated into the photo-initiator system allows Tetric EvoCeram to be less reactive to ambient light while remaining highly reactive to curing lights, so the material won't cure until after placement, and will polymerize quickly once exposed to a curing light. The material's highly esthetic appearance and natural shade blend result from nano-sized fillers which minimize light reflection and improve polishability. Furthermore, the fillers used in Tetric EvoCeram exhibit the same “refractive index” as the monomer, rendering them virtually invisible, creating an exceptional chameleon effect that allows Tetric EvoCeram to blend well with the patient’s natural dentition. Backed by studies involving both anterior and posterior restorations, Tetric EvoCeram demonstrates the longevity and durability required of direct composites. Used in more than 90 million restorations over the past 6 years, Tetric EvoCeram has become a worldwide leader in dental composite materials.
