Abstract

Dental material based on polymerizable (for example ethylenically unsaturated) monomers, epoxides, ormocers, liquid crystal monomers, oxethanes, spiro-orthoesters or spiro-carbonates as binders, a catalyst for cold, hot and/or photo-polymerization, and fillers, and a process for its preparation. Porous glass ceramics, a process for their preparation and uses thereof are also described. Dental materials according to the invention are suitable as alternative materials to the use of amalgam fillings.
