The present invention relates to an orthodontic device and an orthodontic method that can prevent an orthodontic treatment from being eccentrically performed while aligning straightly tooth The orthodontic device includes teeth-attachment unit attached to an orthodontic tooth object; and hook member provided in the teeth-attachment unit and having a connection part of traction unit for orthodontic treatment that is located in the vicinity of a center of resistance (CR) of a tooth In addition, the orthodontic device includes teeth- attachment unit; and hook member provided in the teeth- attachment unit and having a connection part of traction unit for orthodontic treatment that is located in the vicinity of at least gingiva According to the invention, since the teeth-attachment unit of a bracket or a button is substantially horizontal to a traction line of the traction unit connected to the teeth- attachment unit, it is possible to perform the orthodontic treatment effectively without eccentric phenomenon in which the tooth and a dental root are tilted

An orthodontic power arm has a body with a bonding surface for attachment to a tooth. A blade-shaped arm extends gingivally from the body and has a width extending in a mesial-distal direction. The power arm is also equipped with a number of recesses in the mesial or distal edges of the arm for engaging a tractive device. For example, the power arm can be made of a clear polymeric material.

A maxillary skeletal expander is proposed. The maxillary skeletal expander is composed of a pair of dental arch expansion bodies positioned to face each other in an oral cavity; an expanding screw provided between the pair of dental arch expansion bodies to move the dental arch expansion bodies; a guide provided between the pair of dental arch expansion bodies to safely move the dental arch expansion bodies without deviation; a dental arch expansion body combining means having a fixing piece for penetrating a fixing hole at a selected part in the oral cavity, and configured to be combined to and separated from each of the dental arch expansion bodies.

Provided is an orthodontic molar hook capable of preventing objects or food from getting stuck between teeth, and capable of transferring a tractive force directly to the molar without fixing the hook to an orthodontic wire. The orthodontic molar hook(500) is constituted by a head, an extended bar, and a connection hook. The head has a through hole made larger than an orthodontic wire(300). The hook(500) fixes an orthodontic bracket(200) onto a tooth(100) that consists of a fore-tooth(110) and a pre-molar tooth(120). When the orthodontic wire(300) is connected to the bracket(200), a through hole formed in the head is inserted into the orthodontic wire(300) to shift a force towards the pre-molar tooth(120). When the orthodontic molar hook(500) is inserted into a position of the pre-molar tooth(120), the orthodontic wire(300) is fixed onto the bracket(200) to make sure the orthodontic hook(500) not separated from the orthodontic wire(300).

Systems and methods for fabricating indirect bonding trays are disclosed. Physical models of a patient's teeth can be created with non-functional placeholder brackets, impressions of which can be transferred to indirect bonding trays. This can create wells in which functional brackets can be placed into, reducing errors created from transferring functional brackets from the physical model onto the indirect bonding trays.
