Exposure of maxillary gingiva more than 3 mm while smiling is referred to as "excessive gingival display" or "gummy smile." Various treatment options for excessive gingival display are published in the literature, including lip repositioning, crown lengthening, botulinum toxin-A injections, and orthognathic surgeries. This case report aims to present a novel approach to the lip-repositioning procedure for treatment of excessive gingival display. The patient, who visited the department to demand a more esthetic smile, was diagnosed with excessive gingival display caused by hyperactivity of upper lip muscles. Lip repositioning procedure was considered. While evaluating the patient's smile, the amount of gingival display for each tooth region varied. A novel tooth-based modification was planned for the patient for a more precise result. No complication was noted during 10- and 30-day follow-ups. The amount of gingival display while smiling was less than 3 mm for each tooth region. The tooth-based lip-repositioning technique may provide an opportunity to more precisely treat patients with gummy smile.
微笑时上颌牙龈暴露超过3毫米被称为“牙龈过度外露”或“露龈笑”。文献中已发表了多种针对牙龈过度外露的治疗方法，包括唇部重新定位、牙冠延长术、肉毒杆菌毒素A注射和正颌手术。本病例报告旨在介绍一种治疗牙龈过度外露的唇部重新定位手术的新方法。该患者因追求更美观的笑容前来就诊，被诊断为上唇肌肉过度活跃导致牙龈过度外露。考虑进行唇部重新定位手术。在评估患者笑容时，每个牙齿区域的牙龈暴露量各不相同。为该患者计划了一种基于牙齿的改良方法，以获得更精确的效果。在10天和30天的随访中未发现并发症。每个牙齿区域微笑时的牙龈暴露量均小于3毫米。基于牙齿的唇部重新定位技术可能为更精确地治疗露龈笑患者提供机会。
