The treatment of partial jaw needs to be decided according to the specific severity of the patient. If the deviation is mild and does not affect the face much, orthodontic treatment is the main treatment, and the teeth bite relationship is basically normal, then no treatment can be performed, or simple medical cosmetic treatment such as hyaluronic acid filling or Botox injection can be performed. If the degree of deviated jaw is heavy, the asymmetry on both sides is obvious, affecting the function of bite, and has entered the adult stage, growth and development have stopped, surgical treatment is needed to assist orthodontic treatment, that is, combined orthodontic – orthognathic treatment. 1, surgical treatment: surgical methods vary greatly, according to different situations to design the surgical plan, may include the jaw bone osteotomy, re-patching fixed, and chin-plasty used to correct chin deviation, bone grafting or prosthesis placement to meet the need for symmetry. For soft tissue dysplasia deformity, soft tissue filling can be corrected; 2. Oral orthodontics: Surgical procedures can correct abnormal jaw position and improve occlusal relationship, but to achieve satisfactory treatment effect, preoperative and postoperative orthodontic treatment is needed in dentistry. The main purpose is to de-align teeth before surgery, align teeth after surgery, and adjust the relationship between the upper and lower jaw arch.
