ABSTRACT:
An orthodontic traction appliance system including headgear with straps for the wearer, a face plate on either side connected to the headgear, and a resiliently biased "J"-hook tube assembly on each face plate. The "J"-hook tube assembly comprises a "J"-hook member having a shaft extending through a tube and being resiliently and elastically held into the tube by a rubber band extending between lateral arms on the shaft and a reverse, face plate connecting hook on the underside of the tube. The face plate includes a variable length portion comprising a base portion having series of parallel, lateral, female slots and a head strap connector portion riding on the base portion and having a male, inverted-"L" shaped protrusion for mating with a selected one of the female slots to vary the relative distance between the tube of the "J"-hook assembly and the straps of the headgear.
