This application relates to the field of orthodontic appliances and discloses a multifunctional orthodontic traction device, including a self-ligating bracket for fixing and limiting the archwire. The top of the self-ligating bracket is equipped with an elastic closing hook, and a traction structure for orthodontic traction is hooked to the inner side of the elastic closing hook. A combined bracket for adhesive fixation to the posterior teeth is fixedly connected to one side of the traction structure. By using the self-ligating bracket and the combined bracket in conjunction with other brackets and archwires, the device achieves tooth positioning correction. The traction structure, installed between the self-ligating bracket and the combined bracket, generates horizontal tension, thereby performing Class II orthodontic traction on the teeth, achieving horizontal traction. Simultaneously, while the traction structure generates horizontal tension, a downward pressure structure converts part of the force into downward pressure on the molars, thus achieving molar indentation control. This device increases its usability through the integration of multiple functions and improves the efficiency of orthodontic treatment.
