An orthodontic post bondable to a tooth and for use with an orthodontic appliance, such as an aligner, which may be affixed via springs, wires, elastics, or orthodontic connectors in an orthodontic therapy system. The post has a cylindrical main body attached at the bottom end to a bonding pad or base element, and an open top end to receive an attaching element, such as a hybrid orthodontic screw. The body element includes an annular member disposed circumferentially around the body, providing a retaining surface for an orthodontic connector. A through channel through the post can accept an archwire for braces or to which other orthodontic equipment may be mounted.

Orthodontic bracket assemblies with torque-adjusting drums. The drum defines at least a majority of the archwire slot of the corresponding bracket assembly, and the drum may be selectively rotated about its longitudinal axis to adjust the prescriptive force that is applied to a patient's tooth during orthodontic use of the bracket assembly. The bracket assembly includes a positioning assembly that selectively retains the drum in a selected orientation relative to the base of the bracket assembly, thereby defining a prescription to be imparted by the bracket assembly to a patient's tooth. In some embodiments, the bracket assembly includes a biasing mechanism that selectively urges the positioning assembly to a position in which the drum is, or is not, retained in a selected position. In some embodiments, the bracket includes a release mechanism that selectively disengages the positioning assembly to permit adjustment of the drum.

An orthodontic bracket includes a bracket body and a ligating slide. The bracket body includes an aperture and an archwire slot. The ligating slide is slidable relative to the archwire slot between an opened position and a first closed position and is pivotable to an angular position in a second closed position. The orthodontic bracket further includes a resilient member that is coupled to the ligating slide and is slidable in the aperture. The ligating slide defines a first height from the base surface having a first value, and in the second closed position, the ligating slide defines a second height from the base surface that is greater than the first value. The bracket body includes a slide support portion having at least one wing extending laterally therefrom. The wing is tapered in thickness. The slide support portion defines a pivot point about which the ligating slide is pivotable.

In some embodiments, an orthodontic appliance comprises a main body portion, the main body portion including a first end and a second end, wherein the first end is opposite the second end, and wherein the first end includes a first eyelet and the second end include a second eyelet, a first orthodontic device, wherein the first orthodontic device is configured to be bonded to a first tooth in a patient's mouth, wherein the first orthodontic device includes a first protrusion, and wherein the first protrusion is located within the first eyelet during use in the patient's mouth, and a second orthodontic device, wherein the second orthodontic device is configured to be bonded to a second tooth in the patient's mouth, wherein the second orthodontic device includes a second protrusion, and wherein the second protrusion is located within the second eyelet during use in the patient's mouth.

Disclosed is an orthodontic bracket. An orthodontic bracket according to an aspect of the present invention comprises a body attached to teeth, a cover linear-movably and rotatably coupled to the body, and an elastic member which applies pressure to the cover so as to keep the cover locked, wherein the cover is locked to the body while pressing a wire such that the wire is seated in the body.

A self-ligating orthodontic bracket for ligating an archwire includes a bracket body defining an archwire slot configured to receive the archwire, a movable member movable relative to the archwire slot, and an actuator coupled to at least one of the bracket body and the movable member. The actuator includes a ferromagnetic shape memory alloy and is configured to move the movable member when exposed to a magnetic field. A method of orthodontic treatment using a self-ligating orthodontic bracket having an archwire slot configured to receive an archwire therein and including a ferromagnetic shape memory includes exposing at least a portion of the orthodontic bracket to a magnetic field such that the ferromagnetic shape memory alloy at least partially transforms to a martensitic phase from an austenitic phase, and at least one of inserting an archwire into the archwire slot and removing an archwire from the archwire slot.

A bracket body 3 is fixed to a base part 2, and a clip 4 is mounted on the bracket body 3 so as to move. An archwire slot 5 is provided on an upper face of the bracket body 3. A guide groove 9 for guiding a lower extended part 42 of the clip 4 is formed on a lower face of the bracket body 3, and provided at a position below the archwire slot 5. In a state where the slot is closed, an end 45 of the lower extended part 42 does not pass through the bracket body 3 up to a side face at an opposite side to a curved part of the bracket body 3. It is possible to provide an orthodontic bracket which has a lower height and has less possibility that a clip may be detached.

An orthodontic bracket for coupling an archwire with a tooth includes a bracket body configured to be mounted to the tooth and having an archwire slot adapted to receive the archwire therein. A rotatable closure member is movable relative to the bracket body between an opened position in which the archwire is insertable into the archwire slot, and at least one closed position in which the closure member retains the archwire in the archwire slot. The orthodontic bracket further includes a retention mechanism having a first element associated with the bracket body and a second element associated with the closure member, the first and second elements cooperating to rotatably secure the closure member to the bracket body and to provide at least one positive stop in the rotation of the closure member relative to the bracket body.

An orthodontic bracket is disclosed having three archwire retention channels in the mesial-distal directions, a central channel and two side channels. The two side channels each include a pair of spaced apart inverted archwire retaining regions having a recess that opens generally towards the bracket base. Each such recess is for grasping or holding an archwire therein. Other aspects are directed to a self ligating orthodontic bracket system that includes a rotatable member for securing an archwire within a slot of a bracket; embodiments that include an orthodontic appliance and method of producing and using the same, and preferably employed in a lingual orthodontic system, that includes friction reducing features between an interior of an archwire slot portion of the appliance and an archwire placed within the archwire slot.

An orthodontic appliance includes a body portion, and a traction component, a transmission component and an occupying component which are independently provided, the body portion is provided with a slot and an open accommodating cavity communicated with the slot, and the traction component is detachably connected to the accommodating cavity and/or the transmission component; the accommodating cavity accommodates the transmission component, the occupying component is provided in the slot or is provided in the accommodating cavity and the slot, and the transmission component is transmittingly connected to the occupying component; the transmission component is provided with a transmission adaptation position configured to be transmittingly connected to a screwing tool, and the transmission component drives the occupying component to at least partially enter or exit the slot or move in the slot in a slot width direction, so as to change an effective space of the slot.
