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.

A method of constructing an orthodontic appliance assembly comprising the steps of A. Applying a photopolymerizable adhesive to an anchor tooth; B. Placing a metal bracket including a base having a front and a rear surface with holes extending therethrough against the anchor tooth so that the rear surface contacts said adhesive with sufficient pressure to cause said adhesive to extrude through the holes and to flow on the front surface of the base to form heads having greater cross-sections than the diameters of the holes, and C. Applying a source of ultraviolet radiation energy to the adhesive heads extruded through the holes to polymerize the adhesive, whereby the bracket is locked to the anchor tooth.
