The present invention relates to a self-ligating bracket for orthodontics. According to the bracket: space portions are formed on one side of a body unit wherein the space portions are adjacent to each other with respect to a protrusion portion a hooking groove, on which an O-ring is hooked, is formed on the other side of the body unit a hooking portion is formed on the lower surface of a cover unit coupled to the body unit, wherein the hooking portion goes over the protrusion portion and then is positioned in the space portions a projection portion is exposed to the rear side of the body unit so that the O-ring is to be hooked on the projection portion the O-ring is hooked on the hooking groove of the body unit and the projection portion of the cover unit and an upper part of a wire insertion groove of the body unit, through which a wire passes, is finished with the cover unit. Accordingly, orthodontics can be performed by enabling a user to use both an O-ring and a wire at the same time. According to the present invention, while the wire insertion groove is formed in the body unit, the hooking groove and the projection portion, on which an O-ring is hooked, are formed on the body unit and the cover unit, respectively, thereby allowing simultaneous performance of a wire treatment and an O-ring treatment. According to an orthodontic state, a wire and an O-ring can be simultaneously used or either a wire or an O-ring can be selectively used for treatment, such that secondary orthodontics can be performed in various ways. In particular, a structure, where the cover unit covers up the body unit to be connected, is adopted to make the height of the body unit formed relatively short, such that the bracket attached to teeth of a patient subjected to the orthodontics does not come into contact with the oral skin of the patient, thereby enabling the patient subjected to the orthodontics to feel less unpleasant or the sense of difference.본 발명은 치열교정용 자가결착 브래킷에 관한 것으로, 본체부의 타면
