Abstract:
A method of making an occlusally retained mouthpiece which comprises the steps of:providing a substrate;providing a two-part catalytically cured resin precursor which is neither caustic nor irritating to teeth or gingival tissue;said substrate formed from a resin selected from the group consisting of Bisphenol A dialycidyl ether dimethacrylate and urethane dimethacrylate resins and mixtures thereof;said resin precursor being selected from the group consisting of precursors for Bisphenol A diglycidyl ether dimethacrylate and urethane dimethacrylate resins and mixtures thereof;applying a quantity of a mixture of said resin precursor and a catalyst therefor to said substrate;inserting said substrate into a patient's mouth;bringing upper and lower teeth into contact with said substratepressing said substrate against at least one tooth so that said at least one tooth is embedded into said mixture;partially curing said resin precursor to a shape retaining resin state;removing said substrate from said patient's mouth;fully curing said resin to a tough, flexible state bonded to said substrate; andremoving any excess resin from interproximal and undercut areas to allow the cured resin to be fitted over said teeth.
