Abstract:
A polymerizable dental composition comprising:(a) from 3 to 80% by weight of an epoxide or of a mixture of epoxides corresponding to formula I: â€ƒwhere A and Aâ€² independently of one another are optional or represent an unbranched or branched aliphatic, cycloaliphatic or aromatic radical having from 1 to 13 carbon atoms or a combination of these radicals, wherein one or more carbon atoms could be replaced by C&boxH;O, O(C&boxH;O), Si, N or S, B1, B1â€², B2 and B2â€² independently of one another are H, an unbranched or branched aliphatic, cycloaliphatic or aromatic radical having from 1 to 6 carbon atoms or a combination of these radicals, wherein one or more carbon atoms could be replaced by O, (C&boxH;O), O(C&boxH;O), Si, N or S, F and Fâ€² independently of one another are optional or represent an unbranched or branched aliphatic, clycloaliphatic or aromatic radical having from 1 to 10 carbons or a combination of these radicals, wherein one or more carbon atoms could be replaced by (C&boxH;O), O(C&boxH;O), Si, N, or S, D comprises one of the following constituents, which is attached by way of the silicon atom to one or both of A and Aâ€²: i. Si ii. SiG iii. SiGGâ€²G and Gâ€² independently of one another are H, an unbranched or branched aliphatic, cycloaliphatic or aromatic radical having from 1 to 8 carbon atoms or a combination of these radicals, wherein one or more carbon atoms could be replaced by (C&boxH;O), O(C&boxH;O), Si, N or S, n and m independently of one another are 0, 1,2 or 3 and n+m gives from 2 to 4 and the molecular weight of the epoxide or the average molecular weight of the mixture of epoxides is from 250 to 1000 g/mol, (b) from 0 to 80% by weight of an epoxide or of a mixture of epoxides which are different than (a), (c) from 3 to 85% by weight of fillers, (d) from 0.01 to 25% by weight of initiators, retardants or accelerators, (e) from 0 to 25% by weight of auxiliaries, the percentages in each case being based on the total weight of the preparation.
