ABSTRACT:
The invention relates to dental materials based on wax-like polymerizable substances. The dental materials contain (a) 0 to 70 wt. % of at least one polymerizable monomer and/or oligomer; (b) 0.1 to 5 wt. % of at least one polymerization initiator; (c) 0 to 60 wt. % of one or more fillers, (d) at least 20 wt. % of the wax-like polymerizable substance. They can be kneaded at room temperature and can be modelled in non-polymerized state without additional heating, like conventional waxes. On polymerization, the wax component is covalently incorporated into the polymer. The dental materials are suitable for producing temporary and permanent dental prostheses.
