Provided is a dental restorative material having high mechanical strength, abrasion resistance, hardness and excellent aesthetic appearance because it contains a large amount of an ultrafine filler having a particle size of 0.1 .mu.m or less, and can hence be used for restoring molars as well as foreteeth. The dental restorative material comprises an inorganic filler with a size of 0.1 .mu.m or less which is insoluble in water and surface-treated with a silane coupling agent represented by the following general formula: ##STR1## and a (meth)acrylate monomer composition containing at least 50% by weight based on the weight of the composition of at least one hydrophobic multifunctional (meth)acrylate represented by the following general formula: ##STR2## said surface-treated inorganic filler being incorporated in an amount of at least 100 parts by weight based on 100 parts by weight of said monomer composition.
提供的是一种牙科修复材料,其具有高机械强度、耐磨性、硬度和优异的美观外观,因为它含有粒径为0.1微米或更小的超细填料的大量,因此可以用于修复磨牙和前牙。该牙科修复材料包括一种粒径为0.1微米或更小的无水溶性无机填料,其表面经过硅烷偶联剂处理,所述硅烷偶联剂表示为以下通式:##STR1##和含有至少一种疏水性多功能(meth)丙烯酸酯的至少50重量%的(meth)丙烯酸酯单体组成的组合物,所述经过表面处理的无机填料的用量为至少100重量份,基于100重量份的单体组成。
