Background
Currently, orthodontists generally treat patients with teeth or faces with orthodontic appliances, such as brackets, buccal tubes, etc., for example, aiming at the problems of crowding, bucking, uneven tooth arrangement, malocclusion, etc. During conventional orthodontic treatment, an orthodontist attaches a bracket or buccal tube to the surface of a patient's teeth and places an archwire into the archwire slot of the bracket through which the archwire applies corrective forces to the teeth to move the teeth into the correct position. Orthodontic appliances are typically made of metal and are applied to the teeth to affect aesthetics, so some patients choose to apply orthodontic appliances to the lingual side of the teeth for aesthetic purposes during treatment.

Of course, in other embodiments, the seventh locking member may not be additionally provided. Specifically, the first connecting end comprises a rotating part, a rotating hole is formed in the fixing member, the rotating hole extends along the gingival and jaw direction, the rotating part is inserted into the rotating hole, and locking is achieved between the rotating part and the rotating hole through extrusion force between the side wall of the rotating part and the side wall of the rotating hole. For example, the rotating portion is substantially in the shape of an elliptic cylinder, and the corresponding rotating hole is substantially in the shape of an elliptic cylinder, and the pressing force of the rotating portion against the rotating hole is also changed during the rotation of the rotating portion relative to the rotating hole, so that the locking between the rotating portion and the rotating hole can be achieved.
