The gummy smile (GS) or excessive gum visibility (EGV) is an aesthetic concern that affects an individual's attractiveness and personality.
Lip Repositioning surgery (LRP) is a less invasive surgery that can be attributed to treating EGV due to hypermobile lip muscles or mild-to-moderate vertical maxillary excess (VME). Three patients went through LRP surgery by stripping overlying mucosa from the buccal vestibule, followed by suturing the lip mucosa to the mucogingival junction (MGJ), creating shallow vestibule and restricted muscle pull and reducing gingival visibility (GV) during a smile.
Three months of follow-up showed a satisfactory result with 3.67 ± 0.58 mm mean reduction in GV.
牙龈笑（GS）或过多牙龈可见度（EGV）是一种影响个体吸引力和个性的美学问题。
唇部复位手术（LRP）是一种侵入性较小的手术，可归因于治疗因唇肌过度活动或轻度至中度上颌垂直过度（VME）引起的 EGV。三名患者接受了 LRP 手术，方法是从颊侧前庭剥离覆盖的黏膜，然后将唇黏膜缝合到黏膜龈交界处（MGJ），形成浅前庭并限制肌肉拉力，从而减少微笑时的牙龈可见度（GV）。
三个月的随访显示出满意的结果，GV 平均减少 3.67±0.58mm。
