Local anesthesia is used for surgical anesthesia. For isolated small bone tips on the alveolar bone, a blunt instrument can be padded with gauze and directly driven into the alveolar bone. For mild maxillary protrusion, the alveolar space can be removed after tooth extraction, and the labial bone plate can be cut off and pressed toward the lingual side to correct it. For severe maxillary protrusion, depending on the protrusion, the labial bone plate, alveolar space and part of the palatal bone plate can be removed, and then excess soft tissue can be cut off and sutured tightly. In other cases surgical correction is required. For small-scale revision surgery, an arc-shaped incision can be made at the bottom of the alveolar; flaps are removed; bone is removed; the bone surface is filed down; bone debris is removed by irrigation; the wound is sutured intermittently or continuously after mucosa reduction; and sutures are removed in 7 days.
