A dental composition comprising - Polymerizable monomer, - Initiator, - Filler component(s) in an amount of more than 20 wt.-%, with respect to the whole weight of the composition, the polymerizable monomer being characterized as follows: - having exactly two (meth)acrylate reactive moieties, - having an unsymmetrical backbone as linkage between the (meth)acrylate reactive moieties, - the two (meth)acrylate reactive moieties being attached onto the unsymmetrical monomer backbone as alkyl esters, - the unsymmetrical backbone comprising one aromatic moiety of the phenolic type, - having one or two urethane moieties within the unsymmetrical backbone, the polymerizable monomer not containing - an acidic moiety, - other atoms than carbon, hydrogen, nitrogen, and oxygen, - a bisphenol moiety, the polymerizable monomer being characterized by formula with: a = 0 or 1, A = A being always attached as aryl-alkyl ether onto B and / or B', B = *-(CH 2) b -*, *-(CH 2 -CH 2 -O-CH 2 -CH 2)-*, *-(CH 2 -CH 2 -O-CH 2 -CH 2 -CH 2)-*, *-(CH 2 -CH 2 -CH 2 -O-CH 2 -CH 2 -CH 2)-*, B being attached as alkyl ester onto the (meth)acrylate reactive group or as urethane onto D, b = 2 to 6, B' = *-(CH 2) b' -*, *-(CH 2 -CH 2 -O-CH 2 -CH 2)-*, B' being attached as alkyl ester onto the (meth)acrylate reactive group or as urethane onto D', b' = 2-6, D, D' being independently selected from *-(CH 2) n -NH-(C=O)-O-*, *-(CH 2 -C(CH 3) 2 -CH 2)-NH-(C=O)-O-*, *-(CH 2 -CH 2 -C(CH 3) 2)-NH-(C=O)-O-* D and D' being always attached via the oxygen of the urethane linkage onto B and / or B', d = 0 or 1 and d' = 0 or 1 with the proviso that (d + d') = 1 or 2, n = 2 to 5, R being independently selected from H, methyl, X being independently selected from H and C1 to C6 alkyl, "*" representing those site(s) of a moiety of the monomer, where that moiety is bonded to another moiety of the monomer. - Polymerizable monomer, - Initiator, - Filler component(s) in an amount of more than 20 wt.-%, with respect to the whole weight of the composition, - having exactly two (meth)acrylate reactive moieties, - having an unsymmetrical backbone as linkage between the (meth)acrylate reactive moieties, - the two (meth)acrylate reactive moieties being attached onto the unsymmetrical monomer backbone as alkyl esters, - the unsymmetrical backbone comprising one aromatic moiety of the phenolic type, - having one or two urethane moieties within the unsymmetrical backbone, - an acidic moiety, - other atoms than carbon, hydrogen, nitrogen, and oxygen, - a bisphenol moiety, a = 0 or 1, A = A being always attached as aryl-alkyl ether onto B and / or B', B = *-(CH 2) b -*, *-(CH 2 -CH 2 -O-CH 2 -CH 2)-*, *-(CH 2 -CH 2 -O-CH 2 -CH 2 -CH 2)-*, *-(CH 2 -CH 2 -CH 2 -O-CH 2 -CH 2 -CH 2)-*, B being attached as alkyl ester onto the (meth)acrylate reactive group or as urethane onto D, b = 2 to 6, B' = *-(CH 2) b' -*, *-(CH 2 -CH 2 -O-CH 2 -CH 2)-*, B' being attached as alkyl ester onto the (meth)acrylate reactive group or as urethane onto D', b' = 2-6, D, D' being independently selected from *-(CH 2) n -NH-(C=O)-O-*, *-(CH 2 -C(CH 3) 2 -CH 2)-NH-(C=O)-O-*, *-(CH 2 -CH 2 -C(CH 3) 2)-NH-(C=O)-O-* D and D' being always attached via the oxygen of the urethane linkage onto B and / or B', d = 0 or 1 and d' = 0 or 1 with the proviso that (d + d') = 1 or 2, n = 2 to 5, R being independently selected from H, methyl, X being independently selected from H and C1 to C6 alkyl, "*" representing those site(s) of a moiety of the monomer, where that moiety is bonded to another moiety of the monomer.
