The clients with severe mandibular protrusion have problems in occlusion and upper and lower teeth, and need the fundamental correction method of mandibular angle protrusion. First correct the teeth to ensure the normal occlusion and the relationship between the upper and lower teeth after mandibular displacement. After mandibular osteotomy and displacement, it was fixed with screws. After operation, it is required to limit the mouth opening for one and a half months until the bone grows well. When the mandible protrudes forward due to maxillary dysplasia, the displacement of the anterior maxilla will get natural and ideal results. This method of correcting mandibular angle protrusion takes 3 hours under general anesthesia. Orthodontic treatment must be accepted before and after operation. The postoperative hospitalization time is about 10 days, which requires one and a half months of fixation. During the period, you can't open your mouth and have to eat semi-liquid food.
