ABSTRACT:
A new orthodontic bracket assembly is disclosed together with a method of attachment to a tooth wherein a metal orthodontic bracket with a perforated base is attached to the tooth by means of a photopolymerizable adhesive applied to the area to which the bracket is to be affixed. Subsequent exposure of the adhesive, including particularly portions of adhesive extending through the perforations in the bracket base, to electromagnetic energy of predetermined wave lengths and intensity sufficient to polymerize the adhesive thereby affixes the bracket to the tooth.
