<P>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. <P>SOLUTION: The 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 a filler. The adhesives are suitable as light-curing and may include a colorant. Suitable colorants include reversible thermochromic dyes. The adhesives may also include a resin toughening component. <P>COPYRIGHT: (C)2009,JPO&INPIT |
