Photocurable dental composition comprising (a) one or more radical-polymerizable monomers, and (b) 0.1 to 7.0 percent by weight based on the total weight of radical polymerizable monomers in the composition of a compound of the following formula (I): R1R2R3X(CO)X'R4R5R6 (I) wherein X and X' which may be the same or different, independently represent Si or Ge, R1, R2, R3, R4, R5, and R6, which may be the same or different, independently represent a hydrocarbon group having 1 to 20 carbon atoms, whereby any two hydrocarbon groups of R1, R2, R3, R4, R5, and R6 may be bonded to each other and form together with either X, X' or the moiety X(CO)X' to which they are attached a 3 to 12- membered heterocyclic ring, whereby any of the hydrocarbon group or the heterocyclic ring may contain one or more keto groups other than the keto group of the X(CO)X' moiety, or be substituted by on or more groups selected from halogen atoms, a cyano group, an amino group or a hydroxy group, and in case the hydrocarbon group or the heterocyclic ring contains an alkylene chain or an alkenylene chain, one or more carbon atoms in the alkylene chain or alkenylene chain may be replaced by an oxygen atom, a sulfur atom, an amide group, an ester group, a urethane group or an NH group.
光固化牙科组合物包括(a)一种或多种自由基聚合单体,以及(b)相对于组合物中自由基聚合单体的总重量,占0.1至7.0%重量的以下化合物:R1R2R3X(CO)X'R4R5R6(I),其中X和X'可以相同也可以不同,独立地表示Si或Ge,R1、R2、R3、R4、R5和R6可以相同也可以不同,独立地表示具有1至20个碳原子的烃基,其中R1、R2、R3、R4、R5和R6的任意两个烃基可以彼此连接,并与它们附着的X、X'或X(CO)X'基团一起形成3至12个成员的杂环环,其中任何烃基或杂环环均可以含有一个或多个酮基,除X(CO)X'基团的酮基外,任何烃基或杂环环均可以被卤素原子、氰基、氨基或羟基中的一个或多个基团取代,如果烃基或杂环环含有一个烷基链或烯基链,则可以用氧原子、硫原子、酰胺基、酯基、脲基或NH基替换烷基链或烯基链中的一个或多个碳原子。
