    摘要： Radically polymerizable silane according to the general formula I in which R1 is a linear or branched aliphatic C1-C9-alkyl radical, phenyl or alkylated phenyl radical, R2, R3 independently of each other in each case are absent or are a linear or branched aliphatic C1-C20-alkylene radical, which can be interrupted by S or O atoms, R4, R5, R6 independently of each other in each case are —Cl, —O—CH3, —O—C2H5, —CH3 or —C2H5, X is CH2 or O, Y is absent, or is O or NR′, wherein R′ is H or a C1-5-alkyl radical, and Z is absent, or is O, NR″, —CO—O—, —CO—NR″—, —O—CO—O—, —O—CO—NR″—, or —NR″—CO—NR″—, wherein R″ is H or a C1-5-alkyl radical and wherein the radicals R2 and R3 cannot be absent at the same time and Z is absent if R2 or R3 is absent, polycondensates based thereon and fillers surface-modified therewith.

    摘要： Radically polymerizable dental material which contains (a) at least one polyfunctional radically polymerizable monomer, (b) at least one further radically polymerizable monomer which can be monofunctional or polyfunctional, (c) at least one photoinitiator for the radical polymerization and (d) at least one filler. The material is characterized in that the mixture of the monomers (a) and (b) has a refractive index of from 1.50 to 1.70 and in that the refractive index of the monomer mixture before the curing corresponds to the refractive index of the filler used or is higher by up to 0.013 and after the curing is higher than the refractive index of the filler by at least 0.02.
