Maxillary protrusion is mainly treated by surgery, or orthodontic treatment can be carried out during the replacement teeth period, and the specific treatment effect varies from person to person. Maxillary protrusion means that when viewed from the side, the lower jaw is in the normal position of the head and the upper jaw protrudes forward before the lower jaw. Maxillary protrusion not only affects the occlusion of teeth, but also causes cosmetic changes. 1. Permanent dentition: Surgical treatments include orthognathic surgery and tooth extraction surgery. Orthognathic surgery is suitable for patients with severe jaw deformity, and it is necessary to cooperate with orthodontic treatment before and after surgery. Extraction surgery can be performed by removing the supernumerary teeth in the maxillary region, together with orthodontic treatment, and at the same time, correcting the bad habits that exist, thus playing a role in the treatment. 2. Teething period: Orthodontic treatment mainly removes the cause of the disease through various orthodontic appliances and inhibits the forward growth of the maxilla. If you find the maxillary protrusion, you should consult the doctor in time and treat under the doctor’s guidance, do not treat without authorization, so as not to delay the condition.
