For the case that the gum bone and teeth protrude at the same time, protruding oral surgery is a suitable surgical method. Small molars (2 upper teeth and 2 lower teeth) after canine teeth are extracted, and the protruding gums and teeth are pushed into the extraction space to improve the surgical method of protruding problems. The area affected by the operation is only around the mouth. Because the jaw joint has not been improved, it is not suitable for correcting long face and asymmetry.
