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.
