A combination of an orthodontic bracket (10,20) and an arch wire, comprising: a bracket base (21,121,401,601) which is releasably fixable to an anterior facing surface of a patient's tooth; a multiplicity of engagement regions which are formed in a predetermined spatial pattern in the bracket base (21,121,401,601); a bracket body borne on the bracket base (21,121,401,601), and which has an anterior facing surface which defines a transversely disposed arch wire slot, and which further has opposite first and second ends, and wherein the arch wire slot has a selectively adjustable cross-sectional dimension; a bracket body insert which is releasably received within the transversely disposed arch wire slot, and which further has a main body, which forms, at least in part, a portion of the arch wire slot, and wherein the main body of the bracket body insert substantially fixes the rotatable orientation of the bracket body relative to the bracket base (21,121,401,601), the bracket body insert having an engagement member having a distal end, and which is operable to be received within one of the multiplicity of engagement regions formed in the bracket base (21,121,401,601), and wherein the receipt of the distal end of the engagement member in one of the engagement regions releasably fixes the rotatable orientation of the bracket body relative to the bracket base (21,121,401,601); an arch wire received within the transversely disposed, arch wire slot, and wherein the bracket body, acting in combination with the arch wire, is adjustable so as to provide a multiplicity of selective torque expressions which individually, forcibly act upon the patient's tooth, and wherein the orthodontic bracket (10,20) can be employed to achieve a first, second, and third orders of movement of the patient's tooth without a clinically predetermined manipulation of the of the arch wire which is received in the transversely disposed, arch wire slot, and the bracket base (21,121,401,601) may remain affixed to the anterior facing surface of the patient's tooth for an entire orthodontic treatment period, and wherein the transversely disposed arch wire slot is moveable in both a vertical and horizontal plane and has a central region, and wherein rotation of the arch wire slot in either of the vertical or horizontal planes, is maintained about the central region of the arch wire slot, and wherein the bracket body is partially, rotatably moveable relative to the bracket base (21,121,401,601) and in a given axis of movement when the bracket base (21,121,401,601) is mounted on the anterior facing surface of the patient's tooth, and wherein the bracket body can be releasably detached from the bracket base (21,121,401,601), and an alternative bracket body releasably reattached to the bracket base. a bracket base (21,121,401,601) which is releasably fixable to an anterior facing surface of a patient's tooth; a multiplicity of engagement regions which are formed in a predetermined spatial pattern in the bracket base (21,121,401,601); a bracket body borne on the bracket base (21,121,401,601), and which has an anterior facing surface which defines a transversely disposed arch wire slot, and which further has opposite first and second ends, and wherein the arch wire slot has a selectively adjustable cross-sectional dimension; a bracket body insert which is releasably received within the transversely disposed arch wire slot, and which further has a main body, which forms, at least in part, a portion of the arch wire slot, and wherein the main body of the bracket body insert substantially fixes the rotatable orientation of the bracket body relative to the bracket base (21,121,401,601), the bracket body insert having an engagement member having a distal end, and which is operable to be received within one of the multiplicity of engagement regions formed in the bracket base (21,121,401,601), and wherein the receipt of the distal end of the engagement member in one of the engagement regions releasably fixes the rotatable orientation of the bracket body relative to the bracket base (21,121,401,601); an arch wire received within the transversely disposed, arch wire slot, and wherein the bracket body, acting in combination with the arch wire, is adjustable so as to provide a multiplicity of selective torque expressions which individually, forcibly act upon the patient's tooth, and wherein the orthodontic bracket (10,20) can be employed to achieve a first, second, and third orders of movement of the patient's tooth without a clinically predetermined manipulation of the of the arch wire which is received in the transversely disposed, arch wire slot, and the bracket base (21,121,401,601) may remain affixed to the anterior facing surface of the patient's tooth for an entire orthodontic treatment period, and wherein the transversely disposed arch wire slot is moveable in both a vertical and horizontal plane and has a central region, and wherein rotation of the arch wire slot in either of the vertical or horizontal planes, is maintained about the central region of the arch wire slot, and wherein the bracket body is partially, rotatably moveable relative to the bracket base (21,121,401,601) and in a given axis of movement when the bracket base (21,121,401,601) is mounted on the anterior facing surface of the patient's tooth, and wherein the bracket body can be releasably detached from the bracket base (21,121,401,601), and an alternative bracket body releasably reattached to the bracket base.
