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.

An automated procedure for correcting teeth misalignment in orthodontics using the steps of Generating a 3D digital model of a jaw having the misaligned teeth. Processing the 3D model to generate a corrective plan. Designing a set of corrective elements capable of applying corrective forces to the misaligned teeth through elastic forces. Designing a set of attachments that react to the corrective forces. identifying locations for applying the attachments to the surfaces of the teeth; Bonding the attachments to the identified locations. Rescanning the jaw of the patient and generating a final 3D model of the jaw with aligned teeth. Fabricating the corrective element in accordance with geometry of the final 3D model of the jaw. Applying the corrective element to the teeth wherein. Removing the attachments. A second 3D scan can be made to determine errors, and finite element analysis may be used to determine force vectors.

Described is a vibrating device for delivering energy to at least a portion of a dental appliance. The vibrating device may be inserted into a biting element or attached to a biting element to apply vibrations to the dental appliance to aid in aligning a user's teeth.

Devices, systems, and methods for orthodontic treatment planning and orthodontic treatment are disclosed herein. Various embodiments of the present technology, for example, are directed to a method of obtaining data characterizing movements of a patient's teeth from original positions to desired, final positions. In some embodiments, the method can include identifying one or more components of the movements, evaluating the movements, and/or modifying the movements. A method in accordance with several embodiments of the present technology can comprise obtaining an orthodontic treatment plan, which can include one or more suggested interventions to accomplish the tooth movements, a design of such intervention(s), and/or other useful information regarding the orthodontic treatment. In some embodiments, a method of the present technology comprises evaluating an orthodontic treatment during and/or after implementation of the treatment, which can include obtaining data characterizing current positions of the patient's teeth. Based on the evaluation, the method can include obtaining another orthodontic treatment plan and movement data characterizing movements of a patient's teeth from their current positions to desired, final positions.

The present invention represents a qualitative technique modification of the self-uprighting bracket technique. The present invention overcome the drawbacks of the prior art by providing an orthodontic bracket assembly having a base with rotatable body engaging the archwire and removable plate inserted into the base to retain the archwire. In addition, the removable plate can allow or prevent the rotation of the rotatable body depending on the different stages of the treatment.

A crimp stop is made of a metal formed member having a U-shaped cross-section. The metal formed member has a size and shape configured to receive an orthodontic archwire into the U-shaped cross-section and configured to be crimped onto the orthodontic archwire so as to maintain position of the metal formed member after being crimped on the orthodontic archwire by friction. The metal formed member has a curved portion and a pair of legs attached to the curved portion; the legs are not parallel to each other and diverge at an angle.

An orthodontic appliance is provided and includes: a base member fixed to two or more screws implanted in a vicinity of median palatine suture of a palate bone; an arm-shaped arm member having a first connecting portion connected to the base member and a second connecting portion located in a vicinity of palatal side of a tooth; and a traction member that is made of an elastic wire material and pulls a tooth as the traction target. The traction member has a traction base portion, a traction fixation portion, and a traction force generation portion. The traction fixation portion has a bent portion in which the wire material extending along dentition is plastically deformed and bent toward a tooth root side. The bent portion is hooked on a protruding portion protruding to a palate side in a bracket.
