Abstract
An adhesive suitable for use in the oral environment is provided. The adhesive comprises a filler, hardenable resin, a hardener, and a colorant, the composition has an initial color prior to exposure to actinic radiation and a final color that is different from the initial color subsequent to the composition being exposed to actinic radiation. The adhesive can be precoated on to orthodontic appliances.
Claims25
An article comprising:
- an orthodontic appliance having a base for bonding the appliance to a tooth;
- and
- an adhesive on the base of the appliance, the adhesive comprising a filler, a hardenable resin, a hardener, and a photobleachable dye, wherein the hardener comprises a sensitizing compound different from the photobleachable dye, and wherein the adhesive has an initial color prior to exposure to actinic radiation and a final color subsequent to exposure to actinic radiation, the initial color being different than the final color.
An article comprising:
- an orthodontic appliance having a base for bonding the appliance to a tooth;
- and
- an adhesive on the base of the appliance, the adhesive comprising:
- about 70% by weight to about 80% by weight filler comprising quartz and fumed silica;
- about 20% by weight to about 30% by weight hardenable resin comprising bisphenol A diglycidylether dimethacrylate and bis(2-hydroxylethyl)bisphenol-A-dimethacrylate;
- about 0.01% by weight to about 1% by weight hardener comprising camphorquinone, ethyl-4-dimethylaminobenzoate, and diphenyliodonium hexafluorophosphate;
- and
- about 0.01% by weight to about 1% by weight photobleachable dye comprising Erythrosin Yellow blend.
