In some embodiments, apparatuses and methods are provided herein useful to orthodontics. In some embodiments, an orthodontic appliance comprises a body, wherein the body comprises a bonding surface, wherein the bonding surface is configured to be bonded to a surface of a patient’s tooth, a facial surface including an insertion opening, and a compound archwire slot, wherein the compound archwire slot includes an insertion portion and a retention portion, wherein the insertion portion extends into the body from the insertion opening, wherein the retention portion is formed within the body, and wherein the retention portion is angled relative to the insertion opening.

An orthodontic bracket has at least one base configured for attachment to a tooth surface and at least one bracket element arranged at one side of the at least one base, the at least one bracket element comprising—at least one arch wire slot—two wall portions wherein the orthodontic bracket comprises at least one one-piece covering door having at least one first free end which is shaped to fit within at least one indentation of a first wall portion. The at least one indentation comprises at least one locking elevation and the at least one covering door comprises at least one locking deepening. The at least one bracket element and/or the at least one base comprises composite material such as polyurethane material, and/or the at least one covering door comprises composite material such as polyurethane material, and/or comprises ceramic material.

A system is directed to repositioning teeth and includes a first three-dimensional image showing an initial position in which a plurality of teeth are unaligned, and a second three-dimensional image shows a final position in which the plurality of teeth are aligned. The system also includes a plurality of structural domes for respective attachment to the plurality of teeth, the plurality of structural domes being customized and formed based on at least one of the first three-dimensional image and the second three-dimensional image. Each chair-side fabricated dome has at least one internal tunnel that is unaligned with an adjacent internal tunnel in the initial position. A continuous wire is inserted through each internal tunnel of the plurality of structural domes and applies a force to the plurality of structural domes such that adjacent internal tunnels are in alignment with each other in the final position.

This disclosure generally describes an extended buccal tube which is used in connection with braces for the teeth. The extended buccal tube accommodates an arch wire of a sufficient length to allow space to be created between one or more teeth while retaining the arch wire within a tube of the extended buccal tube. As space is created and the arch wire slides through the extended buccal tube, an overall length of the arch wire may be monitored through one or more windows in the extended buccal tube. Tooth pads on extended buccal tube may be rotatable by up to 20° in two axes for fitment purposes. When space has been created between the one or more teeth, extended buccal tube may be cut along scoring lines to separate teeth that were bonded together by the extended buccal tube.

In an embodiment, the present disclosure relates to a segmental distalization device that includes an elongate bar having a distal end and a mesial end, a distal base on the distal end of the elongate bar, a mesial base on the mesial end of the elongate bar, and an attachment member attached to at least one of the elongate bar, the distal base, and the mesial base. In some embodiments, the attachment member is operable to connect the segmental distalization device to an anchor via an elastic connector.

A dental bracket has a base and an engaging unit. The base has two engaged protrusions and two limiting protrusions. The engaging unit is mounted on the base and forms a space between the base and the engaging unit. The engaging unit has a plate, two engaging arms, and a blocking protrusion. The plate has a first surface and a second surface being flat and opposite the first surface. The two engaging arms are formed on the first surface of the plate and respectively engaged with the two engaged protrusions of the base. The blocking protrusion is formed on the first surface of the plate, is arranged between the two limiting protrusions of the base, and divides the space into two channels for inserting an archwire. The second surface of the engaging unit is flat and is able to decrease the foreign body sensation in the mouth.

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.

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.

This disclosure generally describes an extended buccal tube which is used in connection with braces for the teeth. The extended buccal tube accommodates an arch wire of a sufficient length to allow space to be created between one or more teeth while retaining the arch wire within a tube of the extended buccal tube. As space is created and the arch wire slides through the extended buccal tube, an overall length of the arch wire may be monitored through one or more windows in the extended buccal tube. Tooth pads on extended buccal tube may be rotatable by up to 20° in two axes for fitment purposes. When space has been created between the one or more teeth, extended buccal tube may be cut along scoring lines to separate teeth that were bonded together by the extended buccal tube.

A method of aligning teeth and an orthodontic appliance are provided. The orthodontic appliance is configured to be adhered to a surface of a tooth and configured to receive a plurality of differently sized archwires. The orthodontic appliance includes a bonding surface configured to be adhered to the surface of the tooth, an opposing outside surface, a plurality of sidewalls extending between the bonding surface and the opposing outside surface, and an archwire groove extending from a sidewall of the plurality of sidewalls parallelly between the bonding surface and the opposing outside surface.
