Pretreated plastic dental appliances and methods

摘要

A method for pretreating a plastic dental appliance having a surface to be bonded to a tooth comprising applying a pretreatment composition comprising i) a polymerizable component, ii) a solvent capable of at least partially solubilizing the plastic dental appliance, and iii) a photoinitiator system to the surface of the dental appliance. Components i) and ii) may be the same or different materials. The polymerizable component of the pretreatment composition is then polymerized by exposure to actinic radiation. The present invention also provides pretreated plastic dental appliances prepared by this method. Optionally, the plastic dental appliance may additionally be precoated with an orthodontic adhesive and packaged accordingly.
