Abstract: According to one embodiment of the invention, a self-ligating orthodontic bracket apparatus has a body with an archwire slot, a lingual surface for mounting to a tooth and a guide track. The body and guide track form facing surfaces. A clip is engaged between the facing surfaces and is slideably movable in the guide track between an open position such that the archwire slot can receive an archwire and a closed position in which the clip can retain the archwire in the slot. The clip is dimensioned to extend the entire length and height of the slot in the bracket when in the closed position.

Abstract: A self-ligating orthodontic bracket assembly with selectively removable self-ligation features is configured to provide a low profile to minimize labial-lingual prominence. A clip is configured to snap into the base of the bracket and close over the archwire slot to retain the archwire in the slot. The clip is easily moved to an open position when the archwire is changed out during routine treatment. The clip includes spaced apart arms that, along with the bracket tie-wings, straddle the most outwardly prominent site on the crown of the tooth thereby minimizing labial-lingual profile. The self-ligation capability is achieved without any increase in occlusal-gingival height or measial-distal width of the orthodontic bracket.
