Aesthetics is a fundamental part of contemporary dental practice. A pleasant smile depends on the gingival tissue architecture and dental characteristics. Excessive gingival display (gummy smile) is considered an unattractive smile and can affect a person's confidence. There are many etiological factors related to a gummy smile. Aesthetic rehabilitation of these cases often requires an interdisciplinary approach and close collaboration between dental specialties. This article describes an approach to excessive gingival display management caused by short teeth and hyperactive lips using a digital workflow for crown lengthening. A digital approach enables predictable planning and decreases the need for postsurgical modifications, thus shortening the treatment duration. Computer software is used for planning and 3D-printed guide for crown lengthening and implant placement. Two months later, lip repositioning was performed to reduce the hyperactive lip. After 4 months, prosthetic treatment and Botox injections were done to restore an aesthetic smile.
美学是当代牙科实践的一个基本组成部分。一个令人愉悦的笑容取决于牙龈组织结构和牙齿特征。牙龈过度外露（露龈笑）被认为是不美观的笑容，会影响一个人的自信心。与露龈笑相关的病因有很多。这些病例的美学修复通常需要采用多学科方法以及牙科各专业之间的密切协作。本文描述了一种使用数字化流程进行牙冠延长术来处理由牙齿短小和嘴唇过度活跃导致的牙龈过度外露的方法。数字化方法能够实现可预测的规划，并减少术后修改的需求，从而缩短治疗时间。计算机软件用于规划以及牙冠延长术和种植体植入的3D打印导板。两个月后，进行唇部重新定位以减少过度活跃的嘴唇。4个月后，进行修复治疗和肉毒杆菌注射以恢复美观的笑容。
