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.
Claims19
A method for adhesively mounting in the mouth a dental article which is a pontic or a fixed bridge of one or more pontic teeth by securing bonding surfaces on the article to be mounted in the mouth to support surfaces respectively of abutment teeth that are adjacent the mounting location of the article but at opposite sides of it respectively, comprising the steps of:
- (i) etching said support surfaces of said abutment teeth with a suitable chemical etchant;
- (ii) applying a curable dental adhesive to said bonding surfaces on said article and to said etched support surfaces of said abutment teeth;
- and
- (iii) contacting said bonding surfaces with said support surfaces, each surface containing said applied dental adhesive of step (ii), whereby said adhesive hardens to bond the dental article in place,
- wherein said dental adhesive is a methacrylate based dental adhesive comprising from about 2.5% to about 30% by weight of an elastomer or a mixture of two or more of said elastomers, said elastomer or elastomers being selected from the group consisting of homopolymers and copolymers of at least one conjugated diene monomer containing 4 to 10 carbon atoms.
