Beschreibung
Zusammenfassung:	The invention relates to glass ceramics on the basis of the lithium disilicate system, which can be easily mechanically machined in an intermediate stage of the crystallization and which represent high-strength, highly translucent and chemically stable glass ceramics after complete crystallization. Furthermore, the invention relates to a method for producing said glass ceramics. The glass ceramics according to the invention are used as dental material. L'invention concerne des vitrocéramiques, à base d'un système de disilicate de lithium, qui sont facilement façonnables mécaniquement en un stade intermédiaire de cristallisation, et qui constituent, après cristallisation complète, une vitrocéramique hautement résistante, hautement translucide et chimiquement stable. L'invention concerne en outre un procédé de production desdites vitrocéramiques. Les vitrocéramiques selon l'invention trouvent leur application conne matériaux dentaires.
