Abstract
The present invention is directed to orthodontic adhesive formulations, both light curable in the visible wavelength range, and self-curing, for use in the adherence of orthodontic appliances to the surface of etched human teeth. These formulations exhibit a high degree of surface wetting, an available source of leachable fluoride, low polymerization shrinkage, high physical properties and adhesion, and in the light curable embodiment, a post-curing capability.
