Abstract
Abstract An orthodontic arch wire is arcuately curved in the plane of a patient's mandibular dental arch. Respective end portions of the arch wire are offset inwardly for connection with cuspid surrounding orthodontic bands or bonding pads. The arch wire is provided with one or a plurality of selectively positioned transverse closed loops formed by doubling the wire back upon itself to extend in a lingual direction angled downwardly at an angle of 40° to 60° with respect to a plane normal to the plane of the arch wire permitting the arch wire to be flexed away from the patient's teeth against the torsional resistance normally applied to the teeth by the arch wire. The wire flexing feature permits applying one or more tooth position correcting split sleeves to the arch wire.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
143 words
An orthodontic mandibular arch wire for use with orthodontic bands or bonding pads, comprising: a unitary spring wire section substantially U-shaped in the plane of the natural dental arch and having its opposing end portions for connecting to a pair of orthodontic bands or bonding pads secured to a patient's cuspids; at least one transverse closed loop extending laterally and offset from the plane of said U-shaped wire so as to extend in a lingual direction and being located intermediate the ends of said wire section for permitting flexing movement in a lingual direction of intermediate portions of said wire section; and, means interposed between said wire section and a selected tooth of a patient's mandibular dental arch for moving said selected tooth relative to the adjacent teeth by the torsional resistance of that portion of the wire section forming the closed loop.
Claim 2
Dependent Claim
143 words
An orthodontic mandibular arch wire for use with orthodontic bands or bonding pads, comprising: a unitary spring wire section substantially U-shaped in the plane of the natural dental arch and having its opposing end portions for connecting to a pair of orthodontic bands or bonding pads secured to a patient's cuspids; at least one transverse closed loop extending laterally and offset from the plane of said U-shaped wire so as to extend in a lingual direction and being located intermediate the ends of said wire section for permitting flexing movement in a lingual direction of intermediate portions of said wire section; and, means interposed between said wire section and a selected tooth of a patient's mandibular dental arch for moving said selected tooth relative to the adjacent teeth by the torsional resistance of that portion of the wire section forming the closed loop.
Claim 3
Dependent Claim
32 words
The arch wire according to claim 1 in which the respective end portion of said arch wire is offset inwardly for ease of its connection with the orthodontic band or bonding pad.
Claim 4
Dependent Claim
27 words
The arch wire according to claim 1 in which a pair of said closed loops are respectively disposed adjacent the opposing end portions of said arch wire.
Claim 5
Dependent Claim
38 words
The arch wire according to claim 1 in which said closed loop projects downwardly at an angle not less than 40° or greater than 60° with respect to a plane normal to the plane of the arch wire.
Claim 6
Dependent Claim
43 words
The arch wire according to claim 3 in which each loop of said pair of closed loops projects downwardly at an angle not less than 40° or greater than 60° with respect to a plane normal to the plane of the arch wire.
Claim 7
Dependent Claim
37 words
The arch wire according to claim 1 and further including: a split sleeve surrounding said arch wire at a selected location relative to a tooth to be moved; and, means securing said sleeve to the arch wire.
Claim 8
Dependent Claim
43 words
The arch wire according to claim 6 in which the arch wire is provided with a transverse V-shaped recess at the selected sleeve surrounding position and said securing means includes: an indentation in the wall of said sleeve disposed in the V-shaped recess.
