  • Remineralizing dental cements
    Publication number: 20050020720
    Abstract: Remineralizing dental cements contain source(s) of calcium and phosphate ions, adhesive resin monomers, reinforcing base resin monomers, and catalysts able to initiate the polymerization of the adhesive and reinforcing base resin monomers. Such dental cements can be used as orthodontic cements, crown and bridge cements, adhesives, sealants, cavity liners, and protective coatings. The release of calcium and phosphate ions and, optionally, fluoride ions, protects tooth structure from demineralization, a precursor of tooth decay.

  • Single solution bonding formulation
    Patent number: 6649669
    Abstract: A single solution bonding formulation for dental applications comprising a plurality of at least one self-polymerizable polyvinyl acidic monomer or at least two different polymerizable polyvinyl acidic monomers, a calcium phosphate filler, at least one photoinitiator, optionally an accelerator, optionally a solvent, and optionally a fluoride additive is provided. Additionally, a method for treating enamel, dentin, and/or pulp with the same single solution bonding formulation is provided. The single solution bonding formulation provides for the release of calcium, phosphate and/or fluoride ions which are sufficient in situ to form hydroxyapatite and/or fluorapatite.

  • Single-solution adhesive resin formulations
    Patent number: 6114408
    Abstract: Single-solution adhesive resin formulations are made of predominantly dimethacrylates or diacrylates containing (predominantly) two carboxy groups and a functionalized methacrylate or acrylate diluent monomer. A novel light-activated initiator can be used for photopolymerization of such adhesives.
