Excessive gingival display (EGD) is a condition in which an overexposure of the maxillary gingiva (>3 mm) is present during smiling. The proper diagnosis and determination of its etiology are essential for the selection of the right treatment modality. Different techniques have been used in cases of hyperactive upper lip: botulinum toxin injections, lip elongations with rhinoplasties, lip muscle detachments, myotomies, and lip repositions. This report presents a case of a young woman with an EGD larger than 10 mm during smiling caused by altered passive eruption, vertical maxillary excess, and a hyperactive upper lip that was treated with a modified lip repositioning technique and laser gingivectomy because she strongly refused orthognathic surgical treatment. A novel addition to the technique is proposed, a reversible trial accomplished just by applying sutures on the borders of the future split-thickness flap, marked using diode laser, before starting the flap incision.
过度牙龈暴露（EGD）是一种在微笑时上颌牙龈过度暴露（>3毫米）的情况。正确诊断并确定其病因对于选择合适的治疗方式至关重要。在处理上唇活动过度的病例中，已经使用了不同的技术：肉毒杆菌毒素注射、隆鼻术延长唇部、唇部肌肉分离、肌切开术和唇部复位术。本报告介绍了一名年轻女性的病例，她在微笑时由于被动萌出改变、上颌垂直过长和上唇活动过度导致EGD大于10毫米，因强烈拒绝正颌外科治疗，采用改良唇部复位技术和激光牙龈切除术进行治疗。该技术提出了一个新的补充，即在开始皮瓣切口之前，仅通过在未来的中厚皮瓣边界上应用缝线（使用二极管激光标记）来完成可逆试验。
