露齦笑

一名年輕女性出現嚴重露齦笑

露齦笑,又稱笑齦,是一種露出上唇下方牙齦的微笑方式。這是一種常見的臨床疾病,可由牙齒異常萌出(延遲被動萌出)、上唇提肌功能亢進、上顎骨過度垂直生長、上顎前牙過度萌出或上述因素組合引起。 [1] [2]這種疾病有幾種治療方案,可以改善微笑曲綫並減少牙齦暴露。 [3]

治療

治療方案包括牙齒矯正[4]牙齦切除術[5]肉毒桿菌毒素 A注射[6] 、微自體脂肪移植 (MAFT) [7]勒福氏截骨術

肉毒桿菌被認為是最安全且使用最廣泛的注射劑之一。肉毒桿菌( BTX-A )可治療露齦笑。肉毒桿菌豐唇術的效果平均可持續 6 個月。 [8]這種材料會注射到上唇過度活躍的肌肉中,減少嘴唇的向上移動幅度,從而使微笑時減少暴露牙齦[9]肉毒桿菌通常注射到鼻翼外側的三塊唇提肌中,即上唇提肌(LLS)、上唇提肌鼻翼肌(LLSAN) 和顴小肌(ZMi)。 [10]
