Abstract

The invention includes dental materials based on organic plastics in paste form, comprising at least one phase consisting essentially of finely divided, crosslinked plastics which contain copolymerized ester(s) of methacrylic acid to the extent of at least 50% by weight, and the second phase consisting essentially of ester(s) of methacrylic acid to the extent of at least 50% by weight. The materials can be used for making prostheses, crowns, bridges, artificial teeth, dental fillings, etc.
