Abstract
A primer/bonding composition for dental restorations comprising a photoinitiator system and a monomer system consisting essentially of at least one polymerizable acidic component and at least one hydrophilic monomer. The presence of a high viscosity monomer such as Bis-GMA is not required. The composition has excellent bonding properties, and is shelf-stable for at least about one year when stored in one container.
Claims18
A primer/adhesive dental composition, consisting of
- a photoinitiator system;
- a solvent system;
- and
- a polymerizable monomer system, wherein the monomer system consists of
- a polymerizable acidic component;
- a polymerizable hydrophilic component selected from the group consisting of 2-hydroxyethylmethacrylate, 2-hydroxypropylmethacrylate, glyceryl dimethacrylate, diethyleneglycolmethacrylate, triethyleneglycolmethacrylate, tetraethyleneglycolmethacrylate, or combinations thereof;
- and
- trimethylolpropane trimethacrylate, wherein
- the composition is shelf-stable for at least about one year upon mixing.
A dental restoration, comprising a primer/adhesive which is shelf-stable for at least about three months upon mixing, wherein the composition consists of
- a photoinitiator system;
- a solvent system;
- and
- a polymerizable monomer system, wherein the monomer system consists of
- a polymerizable acidic component;
- a polymerizable hydrophilic component selected from the group consisting of
- 2-hydroxyethylmethacrylate, 2-hydroxypropylmethacrylate, glyceryl dimethacrylate, diethyleneglycolmethacrylate, triethyleneglycolmethacrylate, tetraethyleneglycolmethacrylate, or combinations thereof;
- and
- trimethylolpropane trimethacrylate.
A method for bonding a dental restoration, comprising
- applying to a bonding site a primer/adhesive which is shelf-stable for at least about three months upon mixing, wherein the composition consists of
- a photoinitiator system;
- a solvent system;
- and
- a polymerizable monomer system, wherein the monomer system consists of
- a polymerizable acidic component;
- a polymerizable hydrophilic component selected from the group consisting of
- 2-hydroxyethylmethacrylate, 2-hydroxypropylmethacrylate, glyceryl dimethacrylate, diethyleneglycolmethacrylate, triethyleneglycolmethacrylate, tetraethyleneglycolmethacrylate, or combinations thereof;
- and
- trimethylolpropane trimethacrylate;
- at least partially curing the primer adhesive composition;
- and
- adhering a substrate to the bonding site.
