Indirect restorative material system is the result of science born from the success of Herculite XRV™, belleGlass™ NG, and Premise™. Premise Indirect™ utilizes the same “optimized trimodal polymerization” as belleGlass™ NG, the most respected indirect restorative of its kind. Improved shading and polishability creating a long-lasting, smooth polish. Increased opacity in the facial dentins, which produces a natural look and wear.
