Abstract: An orthodontic bracket in two parts includes firstly a base adapted for adhesion to a front of a tooth and including an elongate aperture therethrough, and secondly an elongate, undulated anchor sized for placement by a force fit within the elongate aperture of the base. On opposite ends of the anchor are respectively placed a head having a wire slot that is open on one side passing transversely therethrough, and a lip oriented in the direction of the open side of the bracket and adapted to extend outwardly from the elongate aperture towards the tooth when the anchor is placed within the aperture. The head may have various torque angles so as to provide varying degrees of torque to a tooth upon which applied.

Abstract: A novel intraoral orthodontic appliance for correcting an abnormal jaw condition, or malocclusion, in a patient. The appliance includes an elongate interjaw-force-transferring member having ends which terminate in generally parallel, coplanar closeable loops, with the loops being generally parallel to and spaced apart from the longitudinal axis of the member. A pair of attachment rings are fixed to teeth in different jaws. The loops extend through the attachment rings and are retained therein in a manner providing pivoting of the loops about an axis generally parallel with the plane of the loops. Such construction permits lateral and pivotable movement between the jaws, thereby allowing the patient to eat and speak without interference from the appliance, while still correcting the abnormal jaw condition. The loops may be easily attached to the rings by hooking them on and closing them around the rings with a tool such as a pair of pliers.

Abstract: An improved means of providing adjustable relative pressure between teeth in a fixed-type formative orthodontic appliance employed to increase dental arch size in a treatment plan to overcome crowding or malocclusion is defined. The mechanism is attached to a tooth band means and includes a special screw and arm assembly which is connected to an appropriate tooth pressure-applying clasp. Adjustment of the device may be accomplished by other than a skilled practitioner due to the tooth-band-mounting of the adjustment mechanism. Incorporation of the mechanism in an orthodontic appliance permits desirable reduction in the required bulk of the appliance.
