  • Patent number: 9333149
    Abstract: The subject matter of the invention is a radically polymerizable dental material comprising at least two components. A first component of the dental material contains the salt of a CH-acidic compound, and an additional component contains an acid with acidity greater than that of the CH-acidic compound of the first component. Both components contain radically polymerizable monomers. When the two components are mixed, the acid of the second component converts the salt of the CH-acidic compound of the first component into a CH-acidic molecule, and the CH-acidic molecule triggers the radical polymerization of the monomers. In addition to the advantages of CH-acidic compounds in dental materials on the basis of a reactive resin, the invention achieves long-term storage stability as a result of an increase in the proportion of the reactive resin matrix in polymerizable dental materials.
