Many people turn to protruding mouth plastic surgery, so let’s find out what protruding mouth plastic surgery is all about. It's not a protruding mouth, but there are cases where it looks like a protruding mouth. For example, in the absence of a chin, the lips appear to protrude outwards, so proper self-diagnosis is still required for protruding lips: ① When unconscious, the mouth is open ② The mouth is closed The chin also feels abnormal, and wrinkles appear on the chin. ③ When you smile, your gums will be exposed. ④The lips look very thick. ⑤ The angle formed by the nose and lips should be as small as 90 degrees. ⑥ The chin seems to be missing. ⑦ Judging from the line formed by the nose and chin, most of the lips come out. ⑧ Viewed from the side, the area around the lips looks strange. ⑨ Although I had nose surgery and chin surgery, my lips still protruded outward. If it is not a case of protruding teeth, but if it is a case of protruding gums, just correcting the teeth will not achieve the effect. Even if only the teeth are corrected, only the teeth will move inward, and the gums will still move outwards, which will give people a strange feeling. If the gums are protruding, segmented osteotomy must be performed to push the gums inward. However, this kind of surgery can only be performed after the gum bone has fully grown and matured. If the bone is still in the growth stage, this kind of surgery cannot be performed.
