Abstract
The invention relates to a dental composition comprising a) a compound (A) with the following features: only one backbone unit (U) with 6 to 20 carbon atoms, at least 6 carbon atoms thereof forming an aromatic or an aliphatic cyclic moiety, the remaining carbon atoms either being part of substituents pending from the cyclic moiety or being part of bridging groups to spacer units, wherein one or more of the remaining carbon atoms can be replaced by an oxygen atom, the backbone unit not comprising a bisphenol structure and halogen atoms, one or two unit(s) (S) being connected to the backbone unit (U) via an ether linkage, at least one unit (S) comprising a —CH2-CH2-CH2-CH2-O—CH2-CH(Q)-OG moiety or a —CH2-CH(OG)-CH2-OM moiety or a mixture of these two types of moieties within one unit (S), with G comprising at least one polymerizable moiety and an urethane moiety, the urethane moiety acting as connecting element to unit(s) (S), and M comprising at least one group selected from acroyl, methacroyl, aryl, mixtures and combinations thereof, Q comprising at least one group selected from hydrogen, methyl, phenyl, phenoxymethyl, mixtures and combinations thereof, and with the proviso that onto the backbone unit (U) at least two substituents are attached, each bearing at least one group G, wherein in the case where only one unit (S) is present, the group G not being part of said unit (S) is located in the further substituent pending from unit (U), b) a filler (B) and c) an initiator (C).
