An orthodontic appliance may include an archwire and multiple orthodontic brackets. The archwire may fit within a human mouth and contain multiple male connectors. Each orthodontic bracket may have a configuration that facilitates attaching the orthodontic bracket to a single tooth. Each orthodontic bracket may allow one of the male connectors to be locked into the orthodontic bracket with a snapping action. The male connector may be unable to slide with respect to the orthodontic bracket after being locked in the orthodontic bracket. A manual unlocking action may allow the male connector to disengage from the orthodontic bracket.

Disclosed is a self-ligating crossed buccal tube comprising a bracket body frame structure and a cover plate detachably installed on the bracket body frame structure, which includes four wings, and a first tube cavity for accommodating an archwire is formed by the four wings. Limiting structures are arranged below the first and fourth wings and on a side wall of a first groove. The first tube cavity used for accommodating a thick round wire or square archwire is formed through the four wings. The three limiting structures form two limiting channels used for accommodating a thin round wire. The limiting structures are used for providing a backward tilting moment for teeth, and the problem that the archwire cannot be inserted into the buccal tube after the distal end of the archwire is bent is solved by the sliding cover plate design.

A self-ligating bracket includes a base body, a receiving channel formed in the base body, an elastic body including two elastic clamping arms, a connection part, and a receiving space, a movable lid movably arranged on the base body, a positioner arranged on a bottom of the movable lid and movable in the receiving channel, a sliding opening formed in a wall of the receiving channel, a retaining part formed on an end of the positioner, two avoiding spaces respectively formed between the elastic clamping arms and sidewalls of the receiving channel, and two guide slopes formed on two opposite sides of the positioner. The elastic clamping arms are provided to take the place of a spring or rubber ring in order to improve the durability of the self-ligating bracket and is collaboratively operated with a positioner to feature both advantages of operability and fixing power of the self-ligating bracket.

A self-ligating orthodontic bracket for captivating an archwire with a tooth. The bracket includes a bracket body mountable to a tooth and a self-ligating mechanism having an archwire slot and a ligating slide. The ligating slide is movable between an open position in which an archwire is insertable into the archwire slot and a closed position in which the archwire is retained in the archwire slot. The bracket body may be formed from a non-metallic material, such as a polymer, a filled polymer composite, or a ceramic, and the self-ligating mechanism may be formed from a metal. The bracket may include a resilient engagement member with a detent positioned to engage an aperture or throughhole extending through the ligating slide when the ligating slide is in the closed position.

The invention relates to an orthodontic device which is particularly economical and as small as possible, and which has hooks and a small tube, produced from a sheet metal plate using stamping and bending techniques and without the use of welding or soldering. The orthodontic device comprises a base plate having a flat region with a gingival and an occlusal edge. An occlusal rolling forms the small tube. The gingival edge has a counter-directional rolling. Concave cuts are formed in the side edges in order to form wing-shaped hooks. Both rollings can hold an applicator/protector, with which the orthodontic device is protected during adhesion, and can then be applied to a tooth in the correct orientation.

The present disclosure provides high strength, self-ligating appliances with orthodontically desirable dimensions. The appliances of the present disclosure incorporate a door slidably engaged to a channel in the body; one that can be opened or closed depending on the equilibrium position of an integral protrusion on the door. Cooperating grooves and rails on the body and the door can guide the door between the open and closed positions and mitigate against unintentional detachment.

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.

An orthodontic device can include a bracket configured to support an orthodontic wire. The orthodontic device can include a locking assembly coupled to the bracket and switchable between a plurality of operational modes. The plurality of operational modes can comprise a first sliding mode in which the orthodontic wire is slidable relative to the bracket and a second locked mode in which the orthodontic wire is slidably locked relative to the bracket.
