The correction should be like this. You must go to the orthodontics department first. If the situation is not serious, do orthodontic treatment directly in the orthodontics department and use masking therapy.

If the situation is serious, it is necessary for orthodontists and orthognathic surgeons to work out a comprehensive treatment plan and adopt orthodontics+orthognathic surgery. Orthodontic treatment is needed before and after operation. But the problem is that the landlord is still young and the bone development has not been fully completed. With the development of bone after operation, there will be some deformity, which will affect the final effect. So the landlord can start treatment two years later.
