ABSTRACT:
An improved composite dental material includes an inorganic component of glass particles separated into two interconnected vitreous phases which have been etched to produce a porous surface layer. The inorganic glass particles are combined with an organic resin to provide the composite dental material. Preferable glass compositions include a mixture of silicon dioxide, boron oxide, aluminum oxide and strontium oxide, with one or more from the group of calcium oxide, zinc oxide, stannic oxide, and zirconium oxide as optional modifying ingredients.
