摘要： The present invention discloses a dental restorative material comprising 10-50 mass % of (A) a polymerizable monomer, 5-80 mass % of (B) an organic-inorganic composite filler which is prepared by dispersing an inorganic fine filler having an average particle diameter of 1 μm or smaller in an organic matrix and has an average particle diameter of 5.0-50 μm, and 10-60 mass % of (C) a third component, i.e., an inorganic filler having an average particle diameter of 1.1-5.0 μm, wherein the absolute value of the difference between the refractive index [nC] of the inorganic filler (C) and the refractive index [nB] of the organic-inorganic composite filler (B) (i.e., |nC−nB|) is 0.005-0.07 at 32° C. and the absolute value of the difference between the refractive index [nA] of the cured product of the polymerizable monomer (A) and the refractive index [nC] of the inorganic filler (C) (i.e., |nA−nC|) is 0.005-0.05 at 32° C.
