Abstract
Abstract Packaging for orthodontic brackets having a pre-dispensed adhesive. The packaging comprises light opaque compartments, each compartment sized and dimensioned to contain a bracket, and having a reservoir such that adhesive applied to a portion of the bracket will remain in contact with that portion of the bracket, and will not be distributed over other portions of the bracket. Also, a formulation of adhesive adapted for pre-dispensing to orthodontic brackets, comprising Bis/GMA, EBADMA, and at least one polymerizing agent.
