Patent ID: 8466212

Claim:
A process for preparing dental materials comprising the step of mixing: (a) at least one polymerizable calix[n]arene according to general formula (I), in which n=1 to 5, R 1 -R 4 =independently of one another, H, a C 1 - to C 15 -alkyl radical which can be interrupted by 0, a phenyl radical or a benzyl radical, X 1 represents a group with the structure: Y 1 —R a 1 (Y a 1 —R b 1 -PG 1 ) m , in which Y 1 =not present or O, ester, amide or urethane, R a 1 =an m-valent organic radical comprising from 1 to 30 carbon atoms and also from up to 6 heteroatoms, m=1 to 3, Y a 1 =not present or O, ester, amide or urethane, R b 1 =not present or a C 1 -C 16 -alkylene radical which can be interrupted by oxygen atoms, PG 1 =a polymerizable group X 2 -X 4 =independently of one another, not present, OH or C 1 - to C 10 -alkyl radical and which can have, independently of one another, the same meaning of X 1 and, in addition, can represent a group with the structure: (Y a 2 —R b 2 -AG) p , in which Y a 2 =not present or O, ester, amide or urethane, R b 2 =a p-valent organic radical comprising from 1 to 20 carbon atoms and also from up to 4 heteroatoms, p=1 to 3 and AG=an anchoring group, selected from —P═O(OH) 2 , —O—P═O(OH) 2 , —COOH or —O—SO 2 OH, (b) initiator, (c) at least one additional monomer which polymerize under cationic and/or radical conditions and/or which polymerize by ring opening, the additional monomer comprising mono- or polyfunctional vinylcyclopropanes or bicyclic cyclopropaneacrylates or cyclic allyl sulphides, or polyfunctional (meth)acrylates or mixtures of these monomers, (d) filler, and (e) additive wherein the percentages each time add up to 100%, applying the mixture as cements on tooth, wherein the percentage of cements being (a) 0.5 to 30% by weight of at least one calix[n]arene according to formula (I), (b) 0.01 to 2% by weight of initiator, (c) 1 to 30% by weight of at least one additional monomer which polymerize under cationic and/or radical, conditions and/or which polymerize by ring opening, (d) 5 to 70% by weight of filler and (e) 0.01 to 5% by weight of additive the percentages each time add up to 100%.
