Abstract
The invention provides a divided type dental polymeric core build-up material including a first paste (A) and a second paste (B), in which each of the pastes is a paste obtained by mixing at least a (meth)acrylate monomer, a filler having 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 a fine particle filler having an average particle diameter of primary particles of 0.001 through 0.050 μm, and having a viscosity at 25° C. of 280 through 470 P, and in which one of the pastes includes an oxidant and the other includes a reductant and at least one of the pastes includes a photopolymerization catalyst. The divided type dental polymeric core build-up material of this invention has high operability in core build-up and forms a polymerically cured substance with a good mechanical property.
