An abnormal upper labial frenum is capable of retracting the gingival margin, creating a diastema, limiting lip movement, and in cases of a high smile line, affecting esthetics also. When an abnormal frenum is present, frenectomy is advised. This technique has been modified in many ways. But in most of the techniques the zone of attached gingiva and esthetics are not considered. This case report highlights a new technique of frenectomy that results in good esthetics, excellent color match, gain in attached gingiva, and healing by primary intention at the site of the thick, extensive abnormal frenum.
异常的上唇系带能够牵拉牙龈边缘，形成牙间隙，限制唇部运动，并且在高微笑线的情况下还会影响美观。当存在异常系带时，建议进行系带切除术。该技术已在许多方面得到改进。但在大多数技术中，未考虑附着龈区域和美观问题。本病例报告重点介绍了一种新的系带切除技术，该技术可实现良好的美观效果、出色的颜色匹配、附着龈增加，并使厚且广泛的异常系带部位实现一期愈合。
