USE OF NOVEL GLASS COMPOSITIONS IN PREPARING DENTAL GLASS PILLARS AND SUPPORT PILLARS, AND METHOD FOR PRODUCING THE GLASS PILLARS

摘要

The present invention relates to the use of novel glass compositions in preparing dental glass pillars and support pillars, and method for producing the glass pillars. The glass material comprises a high percent of boron trioxide which makes possible a reduced alkali oxide content. The dental glass pillars thus obtained are bio-compatible and can be used in the preparation of dental bridgework, most preferably when posterior teeth serving for support of the said bridgework are missing.
