PROBLEM TO BE SOLVED: To provide an orthodontic adhesive which improves the ratio (W/C) of working time to curing time since the working time is long and/or the curing time is short.SOLUTION: An orthodontic adhesive includes: a curable resin monomer component; a quaternary curing initiator system; and a 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. |
