The orthodontic bracket according to the invention comprises a body portion (403) and a locking portion (404). In the orthodontic bracket there is a surface (402) against the tooth and a surface (401 ) facing away from the tooth. In the body portion there is an archwire slot (409) for the archwire. There is a locking portion slot (407) in the body portion, which slot is open towards the surface of the orthodontic bracket facing away from the tooth, whereupon it forms an opening (408) on said surface, and the archwire slot is situated in the wall of the locking portion slot. The locking portion can be attached to the body portion. There is a setting slot (411 ) in the locking portion. The locking portion can be rotated into at least two of the following positions: standby position, in which the setting slot is towards the opening on the surface facing away from the tooth, transfer position, in which the setting slot is towards the archwire slot or locking position, in which the locking portion closes the archwire slot at least partially. The archwire can be placed in the setting slot of the locking portion when the locking portion is in standby position, and the archwire can be placed in the archwire slot when the locking portion is in transfer position, and in the locking position the locking portion is arranged to hold the archwire in place in the archwire slot. The archwire or archwires set in place are in locking position arranged to focus force to the orthodontic brackets. The amount and orientation of the force depend on the stress of the archwire and the orientation of the archwire slot.
