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. distal interrupted surface presenting the exit of the longitudinal slot; one interrupted surface presenting the exit of a vertical slot or hole, which in turn joins the longitudinal slot, and upon the securement of the lingual arch wire receives the ninety degree bent portion; and one interrupted lingual surface opposite the surface to be attached to the band presenting a flexure portion to move upon the insertion and withdrawal of a horizontal end of a lingual arch wire, or presenting a recessed portion to accommodate a limited deflection of the lingual arch wire, upon the insertion and withdrawal of this wire and a protuberance in the longitudinal slot located by the flexure portion, or by the recessed portion in another bracket to provide a snap in and snap out function to receive and to discharge the horizontal end of a lingual arch wire, whereby these shaped lingual arch wires are snapped into place using the longitudinal slot and the intersecting vertical slot, and are then held securely in respect to all three geometric planes to provide their accurate control in respect to the molars, with the lingual arch wire being adapted with accuracy, without special pliers at the dental chair locale, saving time, effort, and expense.

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.
