  • Patent number: 11311351
    Abstract: A device for accelerating tooth movement under orthodontic treatment is disclosed. The device includes a vibrational source and a patient-specific tray. The device applies vibrational forces with prescribed frequency and intensity to the teeth under orthodontic treatment with traditional appliances, such as bracket-wire system or aligner. The patient-specific tray ensures the vibrational stimulations on the teeth to be moved. The level of stimulation intensity can be controlled by varying the preload on each of the teeth based on the clinician's prescription. The tray can be further modified to ensure continuous delivery of the desired vibrational forces on the teeth when they move during the treatment.

  • Patent number: 5980246
    Abstract: This invention is an apparatus and method for monitoring and motivating user compliance for orthodontic headgear (24) of the type using a linear spring force module (22). The spring force module (22) includes first (38) and second opposite attachment members that are interconnected to provide spring tension when moved linearly apart. A position sensor (16)(18)(19) detects liner movement between the attachment members. A microprocessor (12) receives signals from the position sensor to determine wear duration, force magnitude, and whether such movement is sufficiently variable to be biological in origin or is attempted mimicry. Multiple determinations made by the processor are recorded over time to provide an evaluation of headgear wear compliance and to provide ongoing motivation for user compliance.

  • Patent number: 5890891
    Abstract: A reverse pull, extraoral dental assembly having at least one head support, at least one body support (e.g., disposed outside of the head region of the dental patient) and at least one chin stop is provided. The head support, body support, and chin stop are interconnected by a brace assembly which is displaced outwardly from the frontal region of the dental patient. One and typically two elastics or other appropriate treatment force generating/transfer members extend from the brace assembly to engage one or more of the dental patient's teeth in the upper and/or lower arch to apply a generally mesially directed treatment force thereto, and/or to engage a device which is directly associated with dental patient bone (e.g., an implant or onplant). The chin support provides a counterforce to any upward force exerted by the assembly thus preventing an upward movement of the assembly.

  • Patent number: 5667380
    Abstract: The invention relates to a tensioning system for an orthodontic outer brace, comprising resilient means, and coupling means for transmitting a tensile force exerted by the resilient means to the outer brace. The resilient means comprise a resilient element. The tensioning system comprises an arc-shaped guide path, along which the resilient element is freely movable. Coupling means can be fixed on one side to the outer brace and are connected to one another on the other side via the resilient element, in such a way that the resilient element moves along the guide path when the patient turns his or her head. The guide path can comprise a tube or an arc-shaped strip of metal or can be formed in some other way. Preferably, the guide path is so flexible that the arc shape thereof can be adjusted to the curvature of the patient's neck. The resilient element preferably has a spring constant which decreases or is zero on further extension after a specific spring force or extension is reached.

  • Patent number: 5651671
    Abstract: A device for applying a force to an orthodontic apparatus in such a manner as to allow a patient or his orthodontist to adjust the force and for recording the force as a function of the time the apparatus is actually worn. In the device, two similar compression springs are arrayed in parallel with one end of each spring pushing against a movable saddle disposed distal from the patient's jaw. The opposite end of each spring abuts a stop which together with the springs and saddle is housed within a case. Belts which extend around the user's head and/or neck hold the case as well as the stop housed therein in fixed position during use. After the device is placed on the patient, the extension of each spring can be adjusted by repositioning the stop. The movable saddle, on the other hand, is fastened to one end of a strap connected to the orthodontic apparatus. Pulling the strap further compresses the two springs between the saddle and the stop.
