  • Patent number: 4380432
    Abstract: Adhesives and methods are provided for fixed prosthesis by bonding a pontic to abutment teeth. The adhesive is preferably a methacrylate based resin adhesive comprising 2.5-30% of an elastomer which is a polymer of a substituted or unsubstituted butadiene monomer. A preferred etchant for preparing the abutment for adhesive bonding is 2-15% HCl. The prosthesis technique does not irreversibly affect the abutment teeth. The preferred adhesive may also be used for immobilizing injured or periodontically affected teeth or for stabilizing teeth in order to retain the results of orthodontic treatment.
