Orthodontic adhesives

摘要

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.

主权项

1. A method of bonding an orthodontic appliance to a tooth surface, comprising:
etching the tooth surface; applying a bonding sealant to the tooth surface; applying a single component light-curable orthodontic adhesive to a surface of the orthodontic appliance; positioning the orthodontic appliance on the tooth surface such that the adhesive is located between the appliance and the bonding sealant; and light curing the orthodontic adhesive, wherein the adhesive comprises:
a curable resin monomer component;a quaternary curing initiator system comprising:
camphorquinone and bis(2,4,6-trimethylbenzoyl)-phenylphosphine oxide,octyldimethylaminobenzoate, and1,1′-azobis(cyanocyclohexane); andfiller.
