| abstract |
The present invention relates to dental materials based on cationically polymerizable monomers as binders, a polymerization initiator and, based on the dental material, 1-95% by weight of at least one inorganic filler, the binder containing monomers of the formula (I) wherein R is hydrogen, a methyl or ethyl group, X and Y each independently represent an unsubstituted or substituted aliphatic, cycloaliphatic or aromatic radical having 1 to 100 carbon atoms, one or more CH 2 groups being represented by O, C = O, -CO 2 - , -SiR 1 2 - and / or -SiR 1 2 O-, in which R 1 independently represents an alkyl or alkoxy or aryl radical having 1 to 10 C atoms, n can be an integer from 1 to 3 and m represents an integer from 2 to 5.n n n The new dental materials are characterized by a specialnlow volume decrease due to hardening andnparticularly good mechanical properties and shortnPolymerization times. |
