Abstract
A microporous filler for dental composite resin restorations has been developed which gives greatly improved finishability, system non-toxicity and x-ray opacification. These fillers are prepared from frits obtained by the low temperature calcination of gelled inorganic 'polymers' followed by a pulsed high-heat treatment.
