Has an opal excellent effect, and stickiness of the paste, polymerization shrinkage during curing is small, and to provide a suitable dental composite restorative material as the repair of the incisal region. In this dental composite restorative material, (A) a polymerizable monomer, (B) an average particle size in the range of 0.1~0.5μm, is 1.30 or less the standard deviation of the particle size distribution silica-based spherical particles [I], preferably organic and inorganic composite filler, were dispersed in an organic resin matrix silica-titanium group oxide composite oxide particles, (C) the silica-based particles [I] and (D I comprises a) a polymerization initiator.優れたオパール効果を有し、ペーストのべたつき感や、硬化時の重合収縮が小さく、切端部の修復用として好適な歯科用複合修復材料を提供する。当該歯科用複合修復材料は、(A)重合性単量体、(B)平均粒子径が0.1~0.5μmの範囲であり、粒子径分布の標準偏差値が1.30以内である球状のシリカ系粒子〔I〕、好適にはシリカ・チタン族酸化物複合酸化物粒子、(C)前記シリカ系粒子〔I〕を有機樹脂マトリックス中に分散させた有機無機複合フィラー、および(D)重合開始剤を含んでなる。
