Polymerizable dental material

摘要

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.

主权项

1. A syringe or cartridge system for providing equal amounts of separate components of a polymerizable dental material, wherein said syringe or cartridge system contains:
a) an amount of an unpolymerized first component comprising:
i) a salt of a CH-acid compound, wherein said CH-acid compound has an acid strength and is able to initiate a radical polymerization, andii) monomers polymerizable under radical conditions, wherein said first component is stable on storage at ambient temperature for more than 3 months; and b) an amount of an unpolymerized second component comprising:
i) an acid having an acid strength that is greater than the acid strength of the CH-acid compound present as a salt in said first component, andii) monomers polymerizable under radical conditions; wherein said first component and said second component contained in said syringe or cartridge system are not in contact, and wherein said syringe or cartridge system is configured to automatically meter and mix said first component and said second component in a ratio of 1:1.
