The objective of this article is to present 3 various types of gummy smile treated with botulinum toxin-A injection per site at Yonsei points. The patients, who visited the department to demand a more aesthetic smile, were classified according to gummy smile type: asymmetric, anterior, and mixed. Botulinum toxin-A injection at Yonsei point was considered. Preinjection and postinjection pictures were taken, and the severity of excessive gingival display was measured for each tooth between second premolars. Two weeks after botulinum toxin injections, no complication was noted. The amount of excessive gingival display for each tooth between second premolars was measured less than 3 mm, and the percentage of improvement for each case was calculated 100%. The botulinum toxin injection at Yonsei point may be a predictable and noninvasive treatment option for various types of gummy smile.
本文的目的是介绍延世点每部位注射A型肉毒杆菌毒素治疗的3种不同类型的露龈笑。因希望获得更美观笑容前来就诊的患者，根据露龈笑类型进行分类：不对称型、前位型和混合型。考虑在延世点注射A型肉毒杆菌毒素。拍摄注射前和注射后的照片，并测量第二前磨牙之间每颗牙齿牙龈过度外露的严重程度。注射A型肉毒杆菌毒素两周后，未发现并发症。第二前磨牙之间每颗牙齿牙龈过度外露的量测量小于3毫米，每例的改善百分比计算为100%。延世点注射A型肉毒杆菌毒素可能是治疗各种类型露龈笑的一种可预测且无创的治疗选择。
