Abstract
Orthodontic traction apparatus for applying traction to the teeth of a patient comprising headgear to be worn by the patient including a pair of side members adapted to be positioned on opposite sides of the patient's head adjacent the ears, and a tensioning assembly on each side member for attachment to an instrumentality associated with the teeth for applying traction thereto. Each tensioning assembly comprises a rod mounted in a guide for sliding movement of the rod axially therein. The guide, in turn, is mounted on the respective side member for axial adjustment relative thereto and also for angular adjustment relative to the side member about an axis extending generally in side-to-side direction with respect to the patient's head. A spring biases the rod to slide axially in the guide to apply traction to the teeth.
