A jaw fracture resulting in severe misalignment of the teeth usually requires surgical repositioning. A jaw fracture bite misalignment is usually caused by a partial or complete fracture of the jawbone due to trauma or other reasons, which prevents the upper and lower teeth from closing properly, constituting an abnormal bite and disruption of biting and chewing functions. Mandibular fracture surgery is required to ensure that the teeth are reset and the bite is normal. Generally, during mandibular fracture surgery, the fracture is repositioned, occlusal function is restored, and the teeth are immobilized. The patient’s jaw fracture is fixed for a period of time or so, the patient can carry out simple mouth opening exercises; diet should be balanced; work and rest should be regular and so on. When this situation occurs, it is recommended to go to the hospital in time.
