Abstract: A self-ligating bracket, a double-wing spacing adjustable bracket and a dental appliance are described. The self-ligating bracket includes a bracket base plate, a first elastic support, a bracket body, and a position-limited member. A first end of the first elastic support is connected to the bracket base plate. The bracket body has a hollow structure. A second end of the first elastic support is connected to a distal end of the bracket body. The distal end of the bracket body is provided with a distal-end gap. The distal end of the bracket body is expanded radially by the second end of the first elastic support. The position-limited member is movable in an axial direction of the bracket body, and the position-limited member is sleeved on an outside of the bracket body for overcoming elastic force provided by the first elastic support and making the bracket body contract in a radial direction.
