| Summary: | The invention relates to dental compositions and methods of use thereof to bind hard tooth, metal and ceramic. The invention provides compositions including complexes formed by reacting multivalent cation with acid moieties of ethylenically unsaturated Monomers and prepolymers. The invention provides compositions with superior adhesion to dentin, enamel and cementum without the need for separate steps of acid etching dental enamel to adhere thereto. Compositions of the invention are useful as dental luting cements, liners, bases and restoratives. The compositions of the invention are hydrolytically stable. The heterogeneous multi-phase dental compositions of the invention show improved mechanical strength, for example, improved bond strength to tooth and are less sensitive to the effects of moisture.
The invention provides dental cement compositions and methods of using them for binding hard tooth material, metal and ceramic. The cement compositions include shelf stable complexes of ethylenically unsaturated monomers reacted with cations. The cements have superior adhesion to tooth without separately acid etching dentin or enamel. Compositions of are useful as dental luting cements, liners, pit and fissure seal bases and restoratives. |
