Premise Universal Composite / Premise Flowable

Premise, a universal composite restorative material, offers high polish, excellent mechanical strength and low polymerization shrinkage all in one system. Three uniquely sized fillers work together to achieve very high-volume loading (84% by weight, 69% by volume).

Material Composition

The body, opaque and translucent shades (except Super Clear) consist of:

  • Trimodal filler system
    1. Prepolymerized filler (PPF), 30 to 50 µm
    2. Barium glass, 0.4 µm
    3. Silica filler 0.02 µm
  • Resin
    1. Ethoxylated bis-phenol-A-dimethacrylate
    2. Triethylene glycol dimethacrylate (TEGDMA)
    3. Light-cure initiators and stabilizers
  • Polymerizable organophosphate dispersant

The Super Clear shade is designed to provide a very high level of translucency (70%). Super Clear is loaded 75% by weight.
