摘要：
Dental composite composition comprises a monomer, cross-linking agent, fillers and initiators, where the cross-linked portion of acrylate monomer with tricyclodecane-urethane-structure (I) is greater than 50% and the hardened composite shows no cytotoxic potential, corresponding to the standard specification according to ISO 10993-5 and DIN EN ISO 7405. Dental composite comprises a monomer, cross-linking agent, fillers and initiators, where the cross-linked portion of acrylate monomer with tricyclodecane-urethane-structure of formula (A-[(-O-CH(R 1>；)-CH(R 2>；)-) n-O-C(=O)-NH-X-NH-C(=O)-O-Z-(-O-C(=O)-C(R 3>；)=CH 2)] r) (I) is greater than 50% and the hardened composite shows no cytotoxic potential, corresponding to the standard specification according to ISO 10993-5 and DIN EN ISO 7405. A : 2-20C aliphatic radical optionally containing 1-3 oxygen bonds, 6-24C aromatic-, 7-26C araliphatic- or 6-26C cycloaliphatic residue； R 1>；, R 2>；H or CH 3； X : octahydro methano indene of formula (II)； R 4>；, R 5>；H, halo, lower alkoxy, lower alkyl or trifluoromethyl； Z : 3-15C divalent aliphatic hydrocarbon (optionally containing 1-3 oxygen bonds and optionally substituted by additional 1-4 (meth)-acrylate residues)； R 2>；, R 3>；H； r : 2-6； and n : 0-5.
