Abstract
Official abstract text for this publication.
A method of removing a dental adhesive may comprise locating the position of the dental adhesive, directing radiant energy into the dental adhesive causing the dental adhesive to weaken a bond formed with the dental adhesive, and breaking the bond by applying a suitable force to overcome the weakened bond. A dental adhesive may comprise a polymer and a dye or pigment, The dental adhesive may be formulated to cure to form a bond that is weakened in response to the dye or pigment absorbing radiant energy subsequent to curing.
First claim
Opening claim text (preview).
What is claimed is: 1. A dental adhesive, comprising: a polymer; and a dye or pigment; and wherein the dental adhesive is formulated to cure to form a bond that is weakened in response to the dye or pigment absorbing radiant energy at a wavelength of about 405 nm subsequent to curing. 2. The dental adhesive of claim 1 , wherein the dye or pigment comprises at least one of a white dye, a white pigment, a translucent dye, and a translucent pigment. 3. The dental adhesive of claim 1 , wherein the dye or pigment comprises at least one of 4,4″-(1,2-ethenediyl)bis-1,1′-biphenyl, and 4,4″-bis[(2-butyloctyl)oxy]-1,1′:4′,1″:4″,1′″-quaterphenyl and 2-[1,1′-biphenyl]-4-yl-6-phenyl-benzoxazole and 3,5,3′″″,5′″″-tetra-t-butyl-p-sexiphenyl and 2-(1-naphthyl)-5-phenyl-oxazole and 3,5,3 . . . ,5 . . . -tetra-t-butyl-p-quinquephenyl. 4. The dental adhesive of claim 1 , wherein the dye or pigment comprises at least one of a yellow dye and a yellow pigment. 5. The dental adhesive of claim 1 , wherein the dye or pigment comprises 2,2″-([1,1′-biphenyl]-4.4′-diyldi-2,1-ethenediyl)bis-benzenesulfonic acid disodium salt. 6. The dental adhesive of claim 1 , wherein the polymer comprises at least one of an acrylic and a methacrylic. 7. The dental adhesive of claim 1 , wherein the polymer comprises at least one of polyethylene glycol methacrylates, polypropylene glycol methacrylates, Diurethane dimethacrylate, hydroxyethyl methacrylate, bis-phenol A diglycidyl dimethacrylate, triethylenegycol dimethacrylate, isodecyl methacrylate, Bisphenol A ethoxylate dimethacrylates, and Poly(ethylene glycol) methyl ether methacrylate.
