A common etiology of excessive gingival display is hypermobile upper lip, which can be managed by non-surgical and surgical approaches. Among the surgical options, lip repositioning surgery is a relatively simple procedure with minimal complications. Since the original description of the technique almost 50 years ago, several minor and major modifications have been introduced. The available evidence indicates that, when applied to properly diagnosed cases, the technique is effective in reducing gingival display and results in improved smile esthetics and high patient satisfaction. This article reviews the various techniques and modifications and summarizes the reported outcomes of the procedure.
上唇过度活动是导致牙龈外露过多的常见原因，可以通过非手术和手术方法进行治疗。在手术方法中，唇复位手术是一种相对简单的手术，并发症较少。自该技术近 50 年前首次描述以来，已经引入了几种小的和大的修改。现有的证据表明，当应用于正确诊断的病例时，该技术可有效减少牙龈外露，改善微笑美观，并获得患者的高度满意度。本文综述了各种技术和修改，并总结了该手术的报告结果。
