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

牙龈组织暴露超过4毫米的微笑被称为露龈笑（GS），会对人们的自信心和美观产生负面影响。GS的治疗应根据潜在病因进行规划，如牙齿被动萌出改变、牙槽突挤出、上颌垂直过度以及唇部肌肉短缩或过度活跃等。在本病例报告中，一名严重GS患者接受了正畸和牙龈成形术治疗，并借助3D模拟、微笑设计和3D打印导板等数字工具辅助。治疗取得了显著且令人满意的效果，无需进行广泛的手术。我们的研究结果表明，牙龈成形术是一种微创、省时且经济高效的替代方法，可替代更广泛的严重牙龈退缩矫正手术。
