ABSTRACT:
Orthodontic traction apparatus adapted for attachment, via elastic bands or the like, to an orthodontic instrumentality associated with the teeth for applying traction to the teeth generally in the forward direction with respect to the head. The apparatus comprises headgear adapted to be worn on the head, and a relatively rigid chin cup adapted for connection to the headgear. An implement in the form of a wire arm extends up from the chin cup for attachment at its upper end, via the elastic bands, to the orthodontic instrumentality. The arm is mounted on the chin cup for movement in the direction of its longitudinal axis for adjustment of the position of the upper end of the arm relative to the mouth and for movement relative to the chin cup generally in side-to-side direction with respect to the head.
