In some embodiments, apparatuses, and methods are provided herein useful to orthodontic appliances. In some embodiments, an orthodontic appliance comprises a main body assembly comprising a base on a first side of the main body assembly configured to be bonded to a patient's tooth, a cavity forming at least a first portion of an archwire slot, and a first mating mechanism, a body subassembly comprising a facial surface that opposes the base, an archwire covering configured to cover at least a portion of the cavity, and a second mating mechanism, wherein the second mating mechanism mates with the first mating mechanism to prevent disassembly of the orthodontic appliance and allow the body subassembly to move from a first position to a second position relative to the main body assembly, wherein when in the second position the archwire covering covers the at least a portion of the archwire slot.

The bracket for orthodontic treatment includes a body; a slot which extends in the vertical plane from the ceiling of the body towards the base thereof and which receives a wire; a lid which moves forwards/backwards so as to open/close the mouth of the slot; a spring and lock group having at least one spring which is provided between the body and the lid, which stretches in the vertical plane and which moves together with the lid with one end being fixed to the lid and the other being free; and a movement mechanism which has at least one rail extending on the ceiling of the body perpendicularly to the slot and at least one slide fitted into said rail and extending downwards from the lower surface of the lid and which enables the lid to move by sliding on the ceiling of the body.

Disclosed is an orthodontic bracket including a bracket body having a slot into which an orthodontic wire is inserted, a bracket cover mounted on the bracket body and configured to open and close the slot, and a ligating member provided in the bracket cover and configured to selectively block the slot so as to confine the orthodontic wire in the slot. The orthodontic bracket may precisely and consistently transmit force, for example, torque, of the orthodontic wire to a tooth, and minimize or prevent factors contributing to failure, such as deformation of or damage to the ligating member due to opening and closing of the slot.

A bracket system for orthodontic appliances including a bracket combinatorial library having a plurality of brackets each interchangeably fixedly mountable to each of a plurality of teeth within a dentition group in a dental arch, whereby the plurality of brackets can be configured to provide incremental variation in tipping force moments, in-out force moments, and torqueing force moments over the entire useful range of orthodontic mechanics, allowing an orthodontic practitioner to prescribe a combination of tipping force moments, in-out force moments, and torqueing force moments unique for each tooth in relation to the plurality of teeth of a patient.

An orthodontic self-ligating bracket for orthodontic treatment of maloccluded teeth. The bracket includes a bracket body, a bracket door, and a spring mechanism retained by the bracket door. The bracket body has a base on the bottom side of the bracket body that is contoured to attach to a surface of a tooth, a bracket slot on the top side of the bracket body extending in a mesiodistal direction and configured to releasably retain an archwire, and a bracket groove on the top side of the bracket body extending in an occlusogingival direction towards the bracket slot. The spring mechanism includes one or more springs that are configured to contact the bracket door and the bracket body. The bracket door can thus be retained by and slidably engage the bracket body between an open position and a closed position. One or more additional active spring members may also be provided.

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.

Self-ligating bracket for orthodontics has a base, an occlusal wall extending from the base and occlusal ligature wing, a gingival wall extending from the base and gingival ligature wing, a slot, which separates the occlusal wall and the gingival wall from one another and extends continuously in the direction from mesial to distal, and a slide, which is held in a guide provided in the occlusal wall and/or in the gingival wall. The guide can be shifted in the gingival-occlusal direction, between a closed position, in which the slide bridges the slot, and an open position, in which the slot is open in labial direction. A structure holds the slide in its closed position as well as in its open position.

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 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.
