Abstract：
A smile that reveals >4 mm of gum tissue is called a gummy smile (GS), offering negative impacts on people\'s self-confidence and aesthetic appearance. The treatment for GS should be planned according to underlying causes such as altered passive eruption of teeth, dentoalveolar extrusion, vertical maxillary excess, and short or hyperactive lip muscles. In this case report, a patient with severe GS received orthodontic and gingivoplasty treatment, aided by digital tools such as 3D simulation, smile design, and 3D printed guides. The treatment yielded remarkable and satisfactory results, without the need for extensive surgery. Our findings suggest that gingivoplasty is a minimally invasive, time- and cost-effective alternative to more extensive procedures for correcting severe gum recession.
摘要：
露出>4毫米牙龈组织的微笑称为牙龈微笑（GS），对人们的自信和审美外观产生负面影响。GS的治疗应根据潜在原因进行计划，例如牙齿的被动萌出改变，齿槽挤压术,上颌垂直过量，和短或过度活跃的嘴唇肌肉。在这个案例报告中,一名患有严重GS的患者接受了正畸和牙龈成形术治疗，在3D仿真等数字工具的帮助下，微笑设计，和3D打印指南。治疗效果明显,满意,不需要大范围的手术.我们的研究结果表明，牙龈成形术是一种微创，时间和成本效益的替代更广泛的程序来纠正严重的牙龈衰退。
