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. |
