Arch Wire Attachment Patents (Class 433/22)
  • Patent number: 10278792
    Abstract: An accessory allows for straight archwires to be converted to looped archwires. The accessory has an archwire receiving channel which is defined between a first elongated coupling member and a second elongated coupling member. The archwire receiving channel is used for crimping the accessory to an existing archwire. An elastically deformable bridge, connected between the first elongated coupling member and the second elongated coupling member, imparts retraction or protraction once activated. The elastically deformable bridge is formed from one or more segments. Curved segments and linear segments are possible, which can be combined to form various shapes, for example omega loops and mushroom shapes. The first coupling member and the second coupling member have an angled lower portion and upper portion to facilitate engagement with existing archwires. Anchoring notches can also be used in conjunction with elastic bands for enhanced orthodontic corrections.

  • Patent number: 9999482
    Abstract: An archwire stop defines a non-linear path through the stop that results in a bend moment between an orthodontic stop and the portion of an orthodontic archwire passing through the stop. The bend moment is accommodated by elastic deformation of the archwire and stop, resulting in a predictable frictional engagement between the stop and the archwire that is useful in maintaining a stop mounted on an archwire during packaging, shipping and handling in a clinical setting. A non-linear path through an archwire stop may be created by a non-linear tubular stop or may be created by appropriate internal features of the stop. The non-linear path through the stop may be selected so that the frictional engagement is greatest toward the free ends of the archwire, preventing the stop from sliding off the ends of an archwire, while permitting adjustment of the stop at the front of the mouth during patient treatment.

  • Publication number: 20020164555
    Abstract: An orthodontic interarch device includes a recurve bend located adjacent a shepherd's hook or loop-type attachment that makes the anterior end of the device rotate downwardly rather than upwardly when force is applied. As the person's jaws move, a cam action against the archwire is produced that does not allow the hook or loop attachment end of the device to move above the horizontal plane of the bite as the connection rotates. The recurve bend should be a minimum of 120 degrees from the longitudinal axis of the interarch device in the backward direction. As the degree of this backward curvature approaches 210 degrees, the recurve bend further positions a hook attachment pivot point below axis of the body of the interarch device in the vertical plane. This further prevents the appliance from rotating into the bite.

  • Patent number: 6120289
    Abstract: An attachment device useful during the course of orthodontic treatment couples an interarch appliance to brackets and/or to archwires placed in the oral cavity. The attachment device includes a wire segment that crosses over a labial side of an archwire in order to enable a coupler of the interarch appliance to slide past the archwire as the patient's jaws are opened. The attachment device increases the range of free sliding motion of the interarch appliance and reduces the amount of stress that might be otherwise imposed on the appliance, on the brackets and/or the archwires as the patient's jaws are opened. The attachment device is particularly suitable for use with Class II correction appliances including elongated, resilient force modules that have an inherent bias toward a normally straight orientation.

  • Patent number: 5842856
    Abstract: A release system for treatment of a broken jaw comprises an upper and lower arch bar conformable to the curvature of the dental arches. The upper arch bar presents a series of interaligned loops which presents a channel for supporting a release bar extending therethrough. Upon wiring the arch bars to the respective dental arches, the lower arch bar is wired to the release bar so as to immobilize the dental arches and associated jaw. Upon imminent vomiting the user removes the release bar from its channel so as to disengage the release bar wiring from the associated upper arch bar. The loop channel supports the release bar so as to prevent kinking and bending of the release bar during wiring and wear. Various arch bars with releasable loops attached thereto are disclosed. Hanger elements for use with individual teeth are also disclosed which define courses for the release bar in lieu of the use of the loop channel on an arch bar. Caps cover the twisted ends of ligature wires to preclude oral abrasion.
