Claim:
Dental material comprising (a) 5 to 90 wt.-% filler that is based on an inorganic filler and that is surface-modified with a compound of the formula (I), [(PG)-R 1 —Z] n —SP—[—R 2 -(AG)] m (I) in which AG is —SiR 3 R 4 X, R 1 is a C 1 -C 3 alkylene group or cyclopropylene group or is absent, R 2 is a C 1 -C 10 alkylene group or is absent, R 3 is a C 1 -C 8 alkyl group, chlorine or OR 5 , R 4 is a C 1 -C 8 alkyl group, phenyl, chlorine or OR 5 , R 5 is a C 1 -C 6 alkyl group, X is OR 5 or chlorine, Z is CO—NR 6 , in which R 6 is H or C 1 -C 6 alkyl, PG is an allyl group, a styryl group, a vinyl cyclopropyl group or a radically polymerizable group of the formula in which R 9 is H, C 1 -C 3 alkyl, C 1 -C 3 hydroxyalkyl or COOR 10 , R 10 is H, C 1 -C 10 alkyl, 1,6-dimethylphenyl or mesityl, R 11 is H or phenyl, m is 1 or 2, n is 1, 2, 3 or 4, SP is absent or an (n+m)-valent linear or branched aliphatic C 1 -C 30 radical in which the carbon chain can be interrupted by O, S, CO—NH, O—CO—NH or NH—CO—NH, an (n+m)-valent aromatic C 6 -C 18 radical, an (n+m)-valent cycloaliphatic C 3 -C 18 radical or an (n+m)-valent heterocyclic C 3 -C 18 radical, wherein the radicals can be substituted with a C 1 -C 5 alkyl, Cl, Br and/or OH or unsubstituted, (b) 9.9 to 90 wt.-% radically polymerizable monomer, (c) 0.1 to 5.0 wt.-% initiator for the radical polymerization, and (d) 0 to 70 wt.-% solvent, each relative to the total mass of the dental material.
