Suggestion: in the field of facial plastic surgery, it is necessary to do plastic surgery of maxillary and mandibular protrusion, that is, alveolar surgery. This treatment is effective only when the lip tissue can completely cover the prominent oral structure, otherwise it needs to be pushed to the alveolar itself. The treatment of pushing into the alveolar itself can be roughly divided into orthodontics and surgery. Although these two methods are similar in concept, they have their own advantages and disadvantages.
