The invention relates to a photopolymerizable composite resin composition for dental restoration 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 this Bis-GMA molecules, and ii) comprising a diluent, an inorganic filler, a photoinitiation system, and other additives. The photopolymerizable composite resin composition for dental restoration based on multifunctional prepolymer mixture has better physical and mechanical properties and biocompatibility than the conventional composition based on only Bis-GMA itself.
