Orthodontics is generally the specialty of orthodontics, which is orthodontics. However, if there are bone problems, orthodontics should cooperate with oral and maxillofacial surgery. First of all, the orthodontist will see you, and if necessary, the doctor will take X-rays, panoramic films, lateral films and CT. Then we will analyze whether it is just a tooth problem or a bone problem. If accompanied by bone problems, the more serious situation is the need to cooperate with orthognathic surgery. Orthodontics generally takes about 2 years, and orthognathic surgery will be more complicated.
