Abstract

Smiling expresses emotions and affects interpersonal relationships, influencing self-esteem and social life. Nowadays, concerns about aesthetics and access to the Internet have made people more informed and demanding about treatments for gingival smile. Excessive gingival display (EGD) is caused by a variety of factors that can act alone or in combination. These factors may include altered passive eruption (APE), vertical maxillary excess, a short upper lip, and hyperactive upper lip, among other factors that cause gingival hyperplasia. In this case report, the EGD was caused by vertical maxillary excess, hypermobility of the upper lip, and APE. The proposed treatment included two procedures: the Modified Lip Repositioning Surgery (Modified LipStat) Technique, with internal sutures to attempt to restrict the traction of the upper lip elevator muscles, and Esthetic Crown Lengthening (ECL) from the right first premolar to the left first premolar for the treatment of APE. The result provided an aesthetic improvement of the smile, with harmonization in relation to the size of the teeth. The mobility of the upper lip in spontaneous smiles remained reduced up to 6 months of follow-up; however, there was a partial relapse in the position of the upper lip during spontaneous smiling at the end of 6 years of follow-up.

摘要

微笑表达情感并影响人际关系，进而影响自尊和社交生活。如今，对美观和互联网信息的获取使人们对牙龈微笑的治疗有了更多了解并提出了更高要求。牙龈过度外露（EGD）由多种因素单独或共同作用引起。这些因素可能包括被动萌出改变（APE）、上颌垂直过长、上唇过短和上唇活动过度，以及其他导致牙龈增生的因素。在本病例报告中，EGD由上颌垂直过长、上唇活动过度和APE引起。建议的治疗包括两个步骤：改良唇重新定位手术（改良LipStat）技术，采用内缝合以试图限制上唇提肌的牵引力，以及从右侧第一前磨牙至左侧第一前磨牙进行美学牙冠延长术（ECL）以治疗APE。结果使微笑的美观度得到改善，牙齿大小更加协调。随访6个月期间，自然微笑时上唇的活动度仍保持降低；然而，随访6年结束时，自然微笑时上唇位置出现了部分复发。
