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.
