Abstract
Orthodontic apparatus for applying traction to the teeth in a patient's mouth via an orthodontic instrumentality on the teeth, comprising headgear having a pair of side members to be worn on opposite sides of the patient's head. Each side member has a tensioning assembly associated therewith for applying traction to the teeth. Each tensioning assembly develops traction upon being stretched. The forward end of each tensioning assembly is adapted to be attached to the orthodontic instrumentality and the rearward end has a fastening rod adapted to be mounted on a side member by a coupler. The coupler has an unlocked and locked configuration. When unlocked, the fastening rod can slide in the coupler relative to the side member so that a predetermined magnitude of traction force may be developed. When locked, the fastening rod is secured against sliding movement so that the traction force may be maintained.
