摘要：
The present invention relates to dental materials comprising liquid, nanoparticulate functionalized hydrophobic co-condensates of tetraalkyl silicates with functionalized trialkoxysilanes of the formula IP—(CH2)n—Si(OR)3 where P, R and n independently of one another have the following meanings:P=a polymerizable CH2═CH—, CH2═CH—O—, styryl, (meth)acrylic or (meth)acrylamide group or an SH group capable of polyaddition,R=methyl, ethyl or propyl andn=from 3 to 15,which can be prepared by co-condensation of tetraalkyl silicates with alkyltrialkoxysilanes functionalized in the ω position and subsequent end group functionalization with trimethylsilyl groups；The invention further relates to the use of the dental materials for filling composites, fixing cements or materials for coatings.
