<p>There is provided a dental composite restorative material which has an excellent opalescent effect, no stickiness of paste, small polymerization shrinkage during curing and is suitable for restoration of incisal edge of a tooth. This dental composite restorative material comprises; (A) a polymerizable monomer, (B) a spherical silica-based particle [ I ]having an average particle diameter in the range of from 0.1 to 0.5µm and a standard deviation of particle diameter distribution within 1.30, preferably a silica-titanium group oxide-composite oxide particle, (C) an organic-inorganic composite filler prepared by dispersing the above-described silica-based particle [ I ]in an organic resin matrix, and (D)a polymerization initiator.</p> |
