ABSTRACT:
A dental composite containing a nanoparticulate filler has a resin matrix with structural element (Ib)R is an open-chain and/or cyclic alkylene, arylene, or alkylene arylene with 1-10 C, optionally modified by oxygen, sulfur, carboxyl or amino, R1is an open-chain and/or cyclic alkylene, arylene, or alkylene arylene with 1-10 C, optionally modified by oxygen, sulfur, carboxyl or amino; R′ is an open-chain and/or cyclic alkyl, alkenyl, aryl, alkyl aryl, or aryl alkyl with 1-20 C; B and B′ are identical or different and are a straight-chain or branched organically polymerizable group with (meth)acrylate residue; R3are identical or different and a bond to another Si or hydrogen, alkyl with 1-10 C, or a bond to another metal atom; a is 1 or 2 and b is 0 or 1.
