Dental material containing a cluster according to the general formula [(M)(M)O(OH)(OR)(L-Sp-Z)] (I) in which M, M, independently of each other, stand in each case for a metal atom of the IIIrd or Vth main groups or the Ist to VIIIth sub-groups of the periodic table; R is an alkyl group with 1 to 6 carbon atoms; L is a co-ordinating group with 2 to 6 complexing centres; Sp is a spacer group or is absent; Z is a polymerizable group; c is a number from 1 to 30; d, e, independently of each other, are in each case a number from 1 to 30; f is a number from 2 to 30, any charge of the cluster (I) present being equalized by counterions.

Dental materials based on metal oxide clusters

The invention relates to iminooxadiazine dione derivatives with the formula (I) in which X, Y and Z represent a (meth)acrylic acid radical of the formula (II) in which Ris hydrogen, an aliphatic hydrocarbon radical with 1 to 14 carbon atoms, which can be interrupted by oxygen atoms, or an aromatic hydrocarbon radical with to 16 carbon atoms; Ris hydrogen, an aliphatic hydrocarbon radical with 1 to 5 carbon atoms or an aromatic hydrocarbon radical with 6 carbon atoms, n is 1 or 2; where the (meth)acrylic acid radical of formula (II) is bound to the radical of formula (I) by Ror Rand the binding point remaining at Ror Ris saturated by hydrogen and X, Y and Z can be the same or different; the individual radicals R being able to be the same or different and selected from alicyclic or aromatic hydrocarbon radicals with 5 to 10 or aliphatic hydrocarbon radicals with 1 to 10 carbon atoms.

(Meth) acrylate-substituted iminooxidiazine dione derivatives

Dental material containing an amide of the general formula BXin which B stands for a hydrocarbon radical with 1 to 5 carbon atoms, which can contain one or more of the groups O, S, NH, CO&#x2014;NH, O&#x2014;CO&#x2014;NH and/or NH&#x2014;CO&#x2014;NH, and which is substituted n times with the group X, X stands for the groupwhich is bound via the nitrogen atom or via C-2 to the radical B, the bond site not connected to B carrying a radical R, Rbeing hydrogen, an alkyl group with 1 to 20 carbon atoms or a phenyl radical, two or more radicals X being able to share a radical Rand Ralso being able to be a constituent of the radical B, Rbeing hydrogen, an alkyl group with 1 to 20 carbon atoms or a phenyl radical, and n being a number from 2 to 5.
