The first end of the main body part is provided on its surface with a first protruding portion, and the first protruding portion has a smooth curved surface. The covering part includes a second surface portion and a second bottom face portion, the second bottom face portion of the covering part matching with the surface of the second end of the main body part. The second surface portion of the covering part is smooth curved such that the second surface portion matches with the surface of the first protruding portion; and the covering part and the main body part are adapted to match and be engaged with each other to form the bracket that is in a smooth curved shape in a gingival direction, an occlusal direction, a mesial direction and a distal direction. An orthodontics system with the bracket and an orthodontic method are also disclosed. The bracket according to the present disclosure is comfortable to use in the mouth, beneficial for oral hygiene and reduces demineralization of the tooth around the bracket and caries.
