The present disclosure discloses a traction bracket, an orthodontic system, and an orthodontic method thereof. The traction bracket includes a traction component, a main body, a cover body and a connecting component, wherein a surface of the main body is provided with a main groove, the main body is provided with a traction hole, one end of the traction hole is opened at a surface of the main body to form an inlet of a cylindrical traction component, and another end of the traction hole is opened at the main groove of the main body to form an arrestment hole, the traction component matches and is connected to the traction hole, the main body is connected to the cover body via a connecting component, and the bottom surface of the cover body matches the surface of the main body and covers the main groove. The traction component of the traction bracket according to the present disclosure can be easily installed, and is equipped with bolt accessories in two specifications, i.e., a traction bolt and an arrestment bolt. The traction bolt can facilitate sliding of the bracket. When the traction bolt is replaced with an arrestment bolt, the movement of the bracket and the arch wire can be stopped, to strengthen anchorage, achieve removal of the clearance between the arch wire and the groove, and achieve the correction effect of accurate expression of the torque of the bracket.
