Abstract: An orthodontic bracket comprises a body having first and second ends, a first vertical sidewall for attachment to a molar band, and a second sidewall extending arcuate and upwardly away from a lower portion of the first sidewall. A contoured slot extends between the ends and downwardly from an upper portion of the first sidewall for defining an upper and a lower channel, and the lower channel permits the second sidewall to flex outwardly relative to the first sidewall. The upper channel includes a lower arcuate surface upon which an orthodontic wire seats. The second sidewall includes a pawl overlying the upper channel and extending substantially the length thereof for engaging and maintaining an orthodontic wire in the upper channel and against the lower arcuate surface.

Abstract: Mirror image orthodontic brackets of an overall elongated block configuration are provided for attachment to bands, in turn secured to molars, to receive respective horizontal ends of lingual arch wires terminating in ninety degree bend portions. The overall elongated block configuration has: one medial surface for attachment to a band to be secured to lingual side of a molar; one interrupted occlusal surface presenting a longitudinal slot to receive a horizontal end of a lingual arch wire; one forward, i.e., mesial, interrupted surface presenting the entry of the longitudinal slot; one rear, i.e.
