Abstract: Orthodontic jaw wiring is a fixed intra-oral, bio-mechanical device and method for treating and controlling compulsive overeating and obesity. The device is composed of orthodontic brackets attached to the teeth, and pliable wire wrapped either around or through the brackets. The brackets are optimally positioned with respect to the anterior-posterior position of the lower jaw. The wiring is configured to suspend the patient's lower jaw in a semi-closed, partially movable resting position which permits a moderate amount of physiologic jaw movement and relatively clear speech, while inhibiting the ingestion of solid foods.
