Abstract
Abstract A modular orthodontics appliance in the form of either an arch wire or a sectional is provided which makes it possible to provide the whole spectrum of three dimensional appliance functions which are geometrically predictable, have positive directional or vector control, and are specifically designed to control the counter-movements in treatment. These modules are designed to be used as coordinates with light wire, edge wire, straight wire and twin wire appliances. Also, they may be used singly or in combination.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
267 words
A lingual assembly for mounting on the lingual side of the teeth of an orthondontic patient, said assembly comprising: a lingual tube bracket for mounting on a first molar of the patient, said bracket including: a first mesial tube having a generally rectangular opening; and a second distal tube having a generally rectangular opening, said tubes being generally parallel to each other and lying along generally vertical axes when mounted on the molar; and a lingual wire, having a longitudinal axis for use in the patient's mouth for effecting selective teeth movements, said wire including: a first mesial post having a generally rectangular cross section receivable in said first mesial tube; a second distal post having a generally rectangular cross section receivable in said second distal tube, said posts being generally parallel to each other and lying in the same plane and perpendicular to the longitudinal axis of said lingual wire; an extender segment extending distally from said distal post which is bendable for use in tooth movement; a connector segment extending mesially from said mesial post; and adjustable activator extending mesially from said connector segment for accomplishing any one of a large variety of orthodontic movements, said activator generally lying in the plane of said posts and, including: a first leg extending downwardly and distally from said connector segment; a second leg extending downwardly and mesially from said first leg; a third leg extending upwardly and mesially from said second leg; a fourth leg extending upwardly and distally from said third leg; and a wire segment extending mesially from the upper end of said fourth leg.
