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, one or two spacer unit(s) (S) being connected to the backbone unit (U) via an ether linkage, at least one spacer unit (S) comprising a -CH2-CH2-CH2-CH2-O-CH2-CH(Q)-OG chain or a -CH2-CH(OG)-CH2-OM residue or a mixture of these two types of spacers within one spacer unit, with G being connected to the spacer unit(s) (S) via an urethane moiety, each group G comprising at least one polymerizable moiety, and M comprising at least one group selected from acroyl, methacroyl, aryl, mixtures and combinations thereof, Q (not being connected to the spacer unit(s) (S) via an urethane moiety and) comprising at least one group selected from hydrogen, methyl, phenyl, phenoxymethyl, mixtures and combinations thereof, b) a filler (B) and c) an initiator (C).
