Patent ID: 7820733

Claim:
A divided dental polymeric core build-up material comprising a first paste (A) and a second paste (B), wherein each of said first paste (A) and said second paste (B) is a paste that includes a (meth)acrylate monomer (I), and a filler composition consisting essentially of a first and second filler, wherein the first filler (II) has a particle size distribution within a range of 0.1 through 40 μm and an average particle diameter of 0.7 through 10 μm and is present in an amount of 190 to 370 parts by weight based on 100 parts by weight of the (meth)acrylate monomer (I), and the second-filler (III) has an average particle diameter of primary particles of 0.005 through 0.045 μm in an amount of 3 to 60 parts by weight based on 100 parts by weight of the (meth)acrylate monomer (I), and has a viscosity at 25° C. of 280 through 470 P, one of said first paste (A) and said second paste (B) includes an oxidant (IV) and the other includes a reductant (V), and at least one of said first paste (A) and said second paste (B) includes a photopolymerization catalyst (VI).
