Abstract

A dental material based on polymerizable monomers is described which contains at least one polymerizable monomer which has liquid crystalline properties. Compared with traditional materials, the dental material displays a lower decrease in volume upon polymerization and, because of its low viscosity, higher filler contents can be achieved.
