Abstract
A method of producing a composite of organic resin and inorganic porous particles, preferably for use as a dental restoration material, which comprises impregnating porous inorganic particles with an at least partially hardenable resin material, compressing or otherwise applying pressure in such a way that the particles contact each other and the pressure in the resin is equalized by viscous flow of excess resin through the pores of the inorganic particles, bonding together by hardening of at least a portion of the hardenable resin material, thereby forming a resin structure including a contiguous inorganic phase.
