Abstract
Abstract An orthodontic bite jumping device for attachment to orthodontic brace wires affixed to the teeth of the upper and lower jaw of a patient for treatment of overbite. The device includes, for each side of the jaw, a telescope mechanism which is mounted at either end on a respective trunnion member affixed to a brace wire located on the upper and lower teeth. Each trunnion member has a radial slot adjacent the inner end for receiving one of the brace wires. The connection between at least one of the ends of the telescope mechanism and the respective trunnion is such as to provide looseness or "play" in the interaction thereof, making the device more flexible and resilient and thus more durable within the mouth, while at the same time maximizing the comfort of the patient.
