Abstract
Primer/bonding-resin compositions include certain hydrophilic monomers, reactive diluent monomers, high viscosity adhesive resins and photo-initiator systems, all provided in a one-component solution containing ethanol or acetone or other suitable solvents. Methods of use of such compositions include a single step application for priming and imparting enhanced adhesion between dental substrates and dental restoratives or components.
Claims40
A primer/bonding-resin composition comprising:
- (A) a polymerizable resin component comprising a mixture of
- (i) at least one of a hydrophilic primer monomer having at least one carboxylic acid group and at least one polymerizable vinyl group, said primer monomer comprising a reaction product of at least one of an anhydride and a dianhydride compound with a compound having at least one vinyl group and at least one hydroxyl group,
- (ii) at least one high viscosity bonding resin compound having at least one reactive vinyl group, and
- (iii) a reactive monomer for diluting the viscosity of at least one of said high viscosity bonding resin compound and said hydrophilic primer monomer, said reactive monomer having at least one vinyl group reactive with at least one of said high viscosity bonding resin and said hydrophilic monomer;
- (B) a photo-initiator system for initiating polymerization of said resin component when said system is combined with said resin component and exposed to activating radiation;
- and
- (C) a solvent for dissolving or suspending said resin component and said photo-initiator system in a flowable form,
- wherein said resin component, said photo-initiator system and said solvent are selected so that a mixture thereof results in a shelf stable composition substantially polymerizable upon exposure of said mixture to at least one of an activating radiation and an external polymerization catalyst.
