Abstract
Disclosed is light-curing dental adhesive compositions i) based on the multifunctional prepolymer mixture of 2,2-bis-(4-(2-hydroxy-3-methacryloyloxypropoxy)phenyl)propane (“Bis-GMA”) and multifunctional prepolymer formed by substituting hydrogen atoms in hydroxyl group with methacrylate groups in the Bis-GMA molecules; and ii) comprising an adhesive monomer having both a hydrophobicity and hydrophilicity, a hydrophilic monomer, a photoinitiation system and a diluent.
Claims8
Light-curing dental adhesive compositions, which show improved physical and mechanical properties, and adhesive performance, comprising:
- (a) 1 to 50 wt % of the prepolymer mixture selected from a group consisting of a mixture of 2,2-bis-(4-(2-hydroxy-3-methacryloyloxypropoxy)phenyl)propane (Bis-GMA) of formula 1 with trifunctional methacrylate (Tri-GMA) of formula 2, a mixture of Bis-GMA With tetrafunctional methacrylate (Tetra-GMA) of formula 3 and a mixture of Bis-GMA, Tri-GMA and Tetra-GMA,
- (b) 1 to 40 wt % of an adhesive monomer;
- (c) 1 to 10 wt % of a hydrophilic monomer;
- (d) 0.1 to 10 wt % of a photoinitiation system;
- and
- (e) 10 to 60 wt % of a diluent,
- wherein the wt % of all the components are based on the total weight of the composition;
