Tooth protrusion wearing braces is helpful, as follows: 1, if it is a dental protrusion or a protrusion patient with a large dental factor, wearing braces will have a significant improvement; 2, if it is a bony protrusion or a protrusion patient with a large bony factor, you need to cooperate with orthognathic surgery treatment. Because the degree of improvement of bony protrusion patients wearing braces is quite limited, if you want to have a greater improvement of the face shape, you still need to cooperate with orthognathic surgery treatment. Orthognathic patients who undergo orthognathic surgery also need the cooperation of orthodontic treatment. Preoperative orthodontics is to adjust the angle of each tooth axis of the teeth, and postoperative orthodontics is mainly fine and occlusal adjustment.
