  • Patent number: 11517404
    Abstract: A self-ligating bracket include a bracket body with an arch wire slot. A mesial recess is located at a mesial side of the bracket body and extends into the bracket body from the arch wire slot. A distal recess is located at a distal side of the bracket body and extends into the bracket body from the arch wire slot. A central ridge defines a ridge surface separated from the lateral ledges respectively by mesial and distal walls. A clip includes a first arm and a second arm connected by a U-shaped portion. The first arm terminates in a mesial arm, a distal arm, and a middle arm. The clip is moveable between an open position in which the arch wire slot is accessible and a closed position in which the arch wire slot is occluded.

  • Patent number: 11259898
    Abstract: An orthodontic device and, in particular, an orthodontic bracket that is slidable along a wire without external forces is provided. The device may include a first and second gear, each of which are independently movable between a locked position in which the gear is prevented from rotation, and a released configuration in which the gear extends into the channel to engage a wire received within the channel and is rotatable to move the device along the wire. The first gear may be rotatable to move the device in a first direction while the second gear may be rotatable to move the device in a second direction opposite the first direction. Thus, the first and second gears have the ability to move along the wire in short or long distances, as desired.

    Abstract: The appliances and methods provide a tab on a ā€œUā€-shaped clip having a labial (i.e. toward the patient's lips or cheek) section and a lingual (i.e. toward the patient's tongue) section. The tab is located in a position that facilitates access by a practitioner and also reduces the moment applied to the clip when the clips is opened and closed. Advantageously, the tab can be positioned to account for the varying degree of resistance encountered by different sections of the clip and minimize the likelihood of either distorting the clip or torquing the appliance. The tab can be positioned coplanar with the sliding mechanism. Advantageously, these appliances can provide improved ease of use, reduced clip distortion over time, and greater patient comfort.

  • Patent number: 9393084
    Abstract: A self-ligating attachment intended to form part of an orthodontic appliance, the external surface of said attachment being provided with a groove for receiving an orthodontic arch. A elastic clip that can be reversibly moved between an open position forming an open passage allowing the insertion of the arch into the groove and a closed position sealing the groove. A base including an external surface that supports the attachment and an occlusal surface which is intended to rest on one of the patient's teeth, so as to hug the surface of the tooth. In addition, the base comprises a support for the attachment and said base assists in the guiding of the clip, cooperating with the attachment, as the clip moves between the open and closed positions.

  • Patent number: 9364298
    Abstract: An orthodontic bracket includes a bracket body, a slide member, and a resilient member. The slide member is slidable relative to the archwire slot. The resilient member is coupled to and is slidable with the slide member. The resilient member is configured to engage a first portion of the bracket body in the opened position and a second portion of the bracket body in the closed position. The second portion is different from the first portion. The resilient member imposes a biasing force on the slide member in the direction of movement toward the archwire slot when the slide member is in the closed position. The resilient member may be configured to impose a biasing force on the slide member in the direction away from the archwire slot when the slide member is at a position intermediate the opened and closed positions.

  • Patent number: 9345558
    Abstract: An orthodontic bracket for coupling an archwire with a tooth includes a bracket body configured to be mounted to the tooth and a clip. A clip slot extends through the bracket body transversely to the archwire slot. Upon deflection of the clip, it contacts the bracket body at locations that were not in contact before the deflection. The clip may also have various forms and include various structures that cooperate with the body when the clip is deflected to restrict or stop the deflection. The orthodontic bracket may include a securing mechanism that is configured to secure the resilient ligating clip in the closed position. A method of manufacturing a shaped unsintered body for use in manufacturing an orthodontic bracket is provided. A portion of the sinterable particles may be removed using a stream of energy to yield a plurality of posts which are then deformed.

  • Patent number: 9089386
    Abstract: A self-ligating orthodontic bracket has a sliding archwire cover that has a top surface congruent with the top surface of an upper body portion having an archwire slot. The cover has a resilient locking tab that slides across the slot, bending upward as it encounters a ridge on the other side of the slot, and latching to the ridge to secure the cover in a closed position. The cover has a modified dovetail shape with flared bottom portions that slideably engage guides for reciprocal opening and closing sliding motion. A groove in the slide support track engages the locking tab in the open position preventing it from disengaging from the upper body portion.

  • Patent number: 9010334
    Abstract: The cheek pouch anchor, formed of a resilient filament, fits within a user's cheek pouch. The anchor dynamically spans a user's inter-occlusal space and lip opening as a user's jaws open and close. The anchor can be formed of inter-connected, conversely-adjustable loops to enable user adjustment of its span. It can stabilize a work piece, such as an airway, in a user's mouth. The cheek path airway fits a path between a user's lips and through the user's cheek pouch and rear-jaw gap, avoiding the user's bite. It provides supplemental air to a user's rear-mouth cavity independently of a user's nasal airways while a user's lips remain closed. It can be used in combination with mandibular jaw-control and tongue-control devices whereby the combination mitigates breathing restrictions in a user's nasal and throat airways. It can be manufactured in-line and folded by a user to fit the user's cheek pathway.

    Abstract: A self-ligating orthodontic bracket includes a bracket body, a slide member, and a resilient member. The slide member is movable relative to the bracket body between an opened position, a first ligating position, and a second ligating position. In the first ligating position and in the second ligating position, a surface of the slide member bounds the archwire slot on a side generally opposite to the base surface to retain the archwire. The resilient member is configured to engage the other of the slide member and the bracket body and has a deformed state for biasing the slide member toward the base surface in at least one of the first and second ligating positions. In the first and second ligating positions, the base surface of the archwire slot and the surface of the slide member are separated by different distances.
