摘要:
A composite filler comprising thermally processed porous inorganic mixed particles of silica and at least one heteroparticle selected from the group consisting of zirconia, hafnia, or yttria and a polymer occupying the pores of the porous inorganic mixed particles, wherein the porous inorganic mixed particles are thermally processed at a temperature of from 650 to 900° C., as well as a dental restorative comprising a resin and a composite filler, and optionally other fillers, wherein said resin has a refractive index that increases upon curing, and wherein the opacities of the both uncured and cured restorative are less than 45.
