Abstract

An orthodontic adhesive includes a curable resin monomer component; a quaternary curing initiator system; and filler. Another orthodontic adhesive having a W/C ratio (working time to curing time ratio) of at least 10, 12, 14 or 20, includes a curable resin monomer component; a curing initiator system; and filler. The adhesives are suitable as light-curing and may include a colorant. Suitable colorants include reversible, thermochromic dyes. The adhesive may also include a resin toughening component.

Claims

exact text as granted — not AI-modified
1 . An orthodontic adhesive, comprising:
 a curable resin monomer component;   a quaternary curing initiator system; and   filler.   
   
   
       2 . The orthodontic adhesive of  claim 1 , further comprising a colorant. 
   
   
       3 . The orthodontic adhesive of  claim 1 , further comprising:
 a resin toughening component.   
   
   
       4 . The orthodontic adhesive of  claim 1 , wherein said curable resin monomer component includes more than one different curable resin monomer. 
   
   
       5 . The orthodontic adhesive of  claim 1 , wherein said quaternary curing initiator system includes at least two sensitizers. 
   
   
       6 . The orthodontic adhesive of  claim 5 , wherein one of said sensitizers is camphorquinone. 
   
   
       7 . The orthodontic adhesive of  claim 5 , wherein one of said sensitizers is a phenylphosphine oxide. 
   
   
       8 . The orthodontic adhesive of  claim 3 , wherein said resin toughening component is a methacrylated urethane resin. 
   
   
       9 . The orthodontic adhesive of  claim 8 , wherein said resin toughening component is an acrylic terminated polyurethane. 
   
   
       10 . The orthodontic adhesive of  claim 4 , wherein said curable resin monomer component includes at least two of the following: bisphenol A diglycidyl ether dimethacrylate, ethoxylated bisphenol A dimethacrylate, ethoxylated trimethylopropane triacrylate, pyromellitic glycol dimethacrylate, triethylene glycol dimethacrylate, glycidyl methacrylate, and glycerol dimethacrylate. 
   
   
       11 . The orthodontic adhesive of  claim 2 , wherein said colorant includes at least one reversible dye. 
   
   
       12 . The orthodontic adhesive of  claim 11 , wherein said reversible dye is thermochromatic. 
   
   
       13 . The orthodontic adhesive of  claim 12 , wherein said reversible, thermochromatic dye has a readily visible, non-tooth colored color below its clearing temperature and is generally tooth colored at body temperature. 
   
   
       14 . The orthodontic adhesive of  claim 1 , wherein said orthodontic adhesive is light-curable. 
   
   
       15 . A light-curable orthodontic adhesive comprising:
 a curable resin monomer component which includes at least two of the following: bisphenol A diglycidyl ether dimethacrylate, ethoxylated bisphenol A dimethacrylate, ethoxylated trimethylopropane triacrylate, pyromellitic glycol dimethacrylate, triethylene glycol dimethacrylate, glycidyl methacrylate, and glycerol dimethacrylate;   a quaternary curing initiator system, which includes two sensitizers;   a reversible, thermochromatic dye; and   filler.   
   
   
       16 . An orthodontic adhesive having a W/C ratio of at least 10, comprising:
 a curable resin monomer component;   a curing initiator system; and   filler.   
   
   
       17 . The orthodontic adhesive of  claim 16  wherein the W/C ratio is at least 12. 
   
   
       18 . The orthodontic adhesive of  claim 16  wherein the W/C ratio is at least 14. 
   
   
       19 . The orthodontic adhesive of  claim 16  wherein the W/C ratio is at least 20. 
   
   
       20 . The orthodontic adhesive of  claim 16 , wherein said curable resin monomer component includes at least two of the following: bisphenol A diglycidyl ether dimethacrylate, ethoxylated bisphenol A dimethacrylate, ethoxylated trimethylopropane triacrylate, pyromellitic glycol dimethacrylate, triethylene glycol dimethacrylate, glycidyl methacrylate, and glycerol dimethacrylate. 
   
   
       21 . The orthodontic adhesive of  claim 16 , wherein said curing initiator system is a quaternary system. 
   
   
       22 . The orthodontic adhesive of  claim 21 , wherein said quaternary curing initiator system includes at least two sensitizers. 
   
   
       23 . The orthodontic adhesive of  claim 22 , wherein one of said sensitizers is camphorquinone. 
   
   
       24 . The orthodontic adhesive of  claim 22 , wherein one of said sensitizers is a phenylphosphine oxide. 
   
   
       25 . The orthodontic adhesive of  claim 16 , further comprising:
 a resin toughening component.   
   
   
       26 . The orthodontic adhesive of  claim 25 , wherein said resin toughening component is a methacrylated urethane resin. 
   
   
       27 . The orthodontic adhesive of  claim 26 , wherein said resin toughening component is an acrylic terminated polyurethane. 
   
   
       28 . The orthodontic adhesive of  claim 16 , further comprising a colorant. 
   
   
       29 . The orthodontic adhesive of  claim 28 , wherein said colorant includes at least one reversible dye.
