A traction bracket, an orthodontic system and an orthodontic method therefor. The traction bracket comprises a traction component, a main body portion (100), a cover body portion (200) and a connection portion (300). A main trough (101) is provided on the surface of the main body portion (100)； a locking traction hole (106) is provided on the main body portion (100)； one end of the locking traction hole (106) is opened in the surface of the main body portion (100) to form a cylindrical traction component inlet, and the other end of the locking traction hole is opened in the main trough (101) of the main body portion (100) to form a locking hole； the traction component is connected to the locking traction hole (106) in a matching manner； the main body portion (100) is connected to the cover body portion (200) via the connection portion (300)； and the bottom surface of the cover body portion (200) matches the surface of the main body portion (100), and covers the main trough (101). The traction component is convenient to install, and is provided with screw accessories of two specifications, namely traction bolts (700, 800a) and locking bolts (600, 800b). The traction bolts (700, 800a) can assist in sliding of the bracket, and the bracket and an arch wire (900) can be locked after the locking bolts (600, 800b) are replaced, thereby enhancing the anchorage, and achieving an orthodontic effect of removing a clearance between the arch wire (900) and the trough and accurately expressing the torque of the bracket.La présente invention concerne un bracket de traction, un système orthodontique et un procédé orthodontique associé. Le bracket de traction comprend un composant de traction, une partie corps principal (100), une partie corps de couvercle (200) et une partie de raccordement (300). Un creux principal (101) est prévu sur la surface de la partie corps principal (100) ； un trou de traction de verrouillage (106) est prévu sur la partie corps principal (100) ； une extrém
