GLASS IONOMER CEMENTS, GLASS POWDER THEREFOR, AND METHODS OF MANUFACTURE

摘要

Glass ionomer cements (GICs) for use as dental materials are formed of generally spherical glass particles. Processes for forming such GICs and glass particles are also disclosed. Conveniently, spherical particles may allow for higher P:L ratios, better integration/packing and have a lower tendency to act as foci of stress concentrations
