Abstract
Abstract A rigid arch wire is fixed in position on bracket-holding tooth bands on selected teeth. Every tooth whose root is to be shifted, has one of such bands thereon, and the bracket associated therewith is rotatably mounted on the arch wire. Any tooth to be swung in, about its root tip as an axis, needs no band thereon. The arch wire serves as a scaffold to support pressure-exerting elements, each of which consists of a sleeve which snaps on and is provided with a securing means, as for instance, a set screw. Resilient fingers or various shapes, or adapted to be bent into various shapes, extend from the sleeve and are adjustably stressible. They are arranged to press on the teeth to be moved, their bands, or against a bracket part as need may require to accomplish the required tooth movement, and may also be made to serve in place of tie wires.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
237 words
An orthodontic system comprising a rigid arch wire, at least two holding members adapted to be securely mounted onto selected teeth of one jaw, said holding members fixedly holding said arch wire in a stationary position relative to said holding members, force-exerting means disposed on said arch wire for exerting pressure on at least one other tooth of said one jaw to move said one other tooth in said one jaw, said force-exerting means being rotatably mounted on said arch wire to any one of a series of angular positions between one angular position to exert a relatively small pressure on said one other tooth and another angular position to exert a relatively large pressure on said one other tooth for adjusting said exerting pressure on said one other tooth, said force-exerting means including a sleeve disposed in rotatable engagement on said arch wire, said sleeve being provided with at least one resilient spring finger, a base portion of said finger being secured to said sleeve with a free portion of said finger extending outwardly from said sleeve to define a cantilever element, said base portion rotating with said sleeve to effect a desired pressure exerted by said cantilever element on said one other tooth, and securing means disposed on said sleeve for releasably securing said sleeve in a selected one of said series of angular positions to maintain said desired pressure on said one other tooth.
Claim 2
Dependent Claim
237 words
An orthodontic system comprising a rigid arch wire, at least two holding members adapted to be securely mounted onto selected teeth of one jaw, said holding members fixedly holding said arch wire in a stationary position relative to said holding members, force-exerting means disposed on said arch wire for exerting pressure on at least one other tooth of said one jaw to move said one other tooth in said one jaw, said force-exerting means being rotatably mounted on said arch wire to any one of a series of angular positions between one angular position to exert a relatively small pressure on said one other tooth and another angular position to exert a relatively large pressure on said one other tooth for adjusting said exerting pressure on said one other tooth, said force-exerting means including a sleeve disposed in rotatable engagement on said arch wire, said sleeve being provided with at least one resilient spring finger, a base portion of said finger being secured to said sleeve with a free portion of said finger extending outwardly from said sleeve to define a cantilever element, said base portion rotating with said sleeve to effect a desired pressure exerted by said cantilever element on said one other tooth, and securing means disposed on said sleeve for releasably securing said sleeve in a selected one of said series of angular positions to maintain said desired pressure on said one other tooth.
Claim 3
Dependent Claim
49 words
An orthodontic system according to claim 1, wherein said sleeve is of resilient material and split lengthwise to allow said sleeve to be snapped onto said arch wire, said sleeve encircling more than half-way around said arch wire to permit sliding movement of said sleeve along said arch wire.
Claim 4
Dependent Claim
23 words

Claim 6
Dependent Claim
92 words
An orthodontic system according to claim 4, including a band member to be securely mounted onto said one other tooth, a bracket fixed on said band member, said bracket being provided with a channel thereacross, said arch wire being positioned through said channel, means holding said arch wire in said channel with said bracket being rotatable on said arch wire, said one arm of said finger being in contact with one of said bracket, said bracket, said band member and said one other tooth at a place spaced from said arch wire.
Claim 7
Dependent Claim
52 words
An orthodontic system according to claim 5, wherein said bracket includes a wing portion spaced from said band member to define said channel, said wing portion being provided with a bight channel, said means holding said arch wire including a locking pin disposed in said bight channel to engage said arch wire.
Claim 8
Dependent Claim
17 words

Claim 9
Dependent Claim
48 words
An orthodontic system according to claim 1, wherein said sleeve is provided with at least two resilient spring fingers, each of said two fingers being L-shaped with one arm of each finger being spaced from said sleeve, said one arms extending in opposite directions along said arch wire.
Claim 10
Dependent Claim
38 words
An orthodontic system according to claim 8, wherein one of said two fingers is disposed to one side of said arch wire, and the other of said two fingers is disposed to another side of said arch wire.
Claim 11
Dependent Claim
20 words
An orthodontic system according to claim 8, wherein said two fingers are disposed to one side of said arch wire.
Claim 12
Dependent Claim
