Excessive gingival display (EGD) is a common esthetic concern. Lip repositioning surgery (LRS) was introduced as one of the treatment options to manage EGD. LRS can be used for skeletally and/or muscularly induced EGD. The present case series applied LRS using an Er,Cr:YSGG laser to treat 24 patients with minor vertical maxillary overgrowth or a hypermobile lip. At 6 months, the gingival display had decreased by 3.79 ± 1.59 mm (mean ± standard deviation), and the visible lip body when smiling had increased by 1.23 ± 0.74 mm. A questionnaire revealed that the level of satisfaction with the smile increased among the patients and that they had a positive attitude toward Er,Cr:YSGG laser-assisted LRS.
牙龈过度外露（EGD）是一种常见的美学问题。唇重新定位手术（LRS）作为治疗EGD的选择之一被引入。LRS可用于骨骼和/或肌肉因素导致的EGD。本病例系列应用铒铬：钇钪镓石榴石（Er,Cr:YSGG）激光进行LRS，治疗24例轻度垂直上颌骨过度生长或唇部活动过度的患者。6个月时，牙龈外露减少了3.79±1.59毫米（平均值±标准差），微笑时可见的唇部增加了1.23±0.74毫米。一份问卷调查显示，患者对微笑的满意度提高，且他们对Er,Cr:YSGG激光辅助LRS持积极态度。
