1. A dental curable composite material comprising
(a) one or more compound(s) of the structure Q-[(Y)n-X]o which are not free-radically polymerizable during curing with constituent (b), wherein:
Q is a tricyclic structural element wherein one, two or more of the hydrogen atoms not substituted by Yn-X substituents in this tricyclic structural element Q are optionally replaced by alkyl groups, alkoxy groups, halogen atoms or trifluoromethyl groups;Y is methylene (—CH2—);n =0 or 1;X is selected from the group consisting of —O—Z, —N—(Z)2, —NH—Z, —O—C(═O)—Z, —C(═O)—O—Z, —O—C(═O)—NH—Z, —NH—C(═O)—O —Z, —NH—C(═O)—NH—Z, —C(═O)—NH—Z, —NH—C(═O)—Z, —C(═O)—N—(Z)2, —N—(Z) —C(═O)—Z, —O—C(═O)—N(Z)—C(═O)—NH—Z,—NH—C(═O)—N(Z)—C(═O)—NH—Z, —N(C(═O)—NH—Z)2, —C(═O)—N(Z)—C(═O)—NH—Z,—N(C(═O)—NH—Z)(C(═O)—Z), and —N(C(═O)—NH—Z)(C(═O)—O—Z), wherein the bond arranged on the left in each formula is closer to the structural element Q and wherein X is selected such that Z has a minimum number of atoms,Z is an organic radical having at least one carbon atom, and each Z may be the same or different, ando =2, 3, or 4, and (b) further constituents comprising (b-1) one or more different monomer(s) selected from the group consisting of (meth)acrylates, (b-2) one or more fillers, and (b-3) one or more photoinitiator(s) and/or one or more initiator(s) for chemical curing. |
