Abstract：
During or after the orthodontic closure, persistent diastemas are frequently the result of a high frenum attachment. A labial frenectomy is a complete removal of the frenum attachment, which typically attaches to the space between the upper two anterior teeth and the centre of the upper lip. It might be required if there is space between the teeth due to a frenulum positioned too high on the gums. Many surgical technique modifications, including Miller\'s technique, Z-plasty, and V-Y-plasty, have been established since the conventional classical frenectomy procedure was initially presented to cope with the difficulties associated with an aberrant labial frenum. This case report demonstrates that a Z-plasty approach was used to remove the 21-year-old female patient\'s high papillary-type labial frenum attachment and how orthodontic treatment led to the closure of the midline diastema. For several reasons, the frenectomy procedure with Z-plasty proved to be reliable and yielded outstanding aesthetic outcomes for the removal of the aberrant labial frenum connection. Understanding Z-plasty will enable primary intention-based tissue healing, reduce the risk of tissue contractures, shorten the patient\'s recovery, and enhance the patient\'s aesthetic outcomes.
摘要：
在正畸闭合期间或之后，持续的纵隔通常是高系带依恋的结果。唇系切除术是指完全切除系带附件，通常连接到上两个前牙和上唇中心之间的空间。如果由于系带在牙龈上过高而在牙齿之间存在空间，则可能需要。许多手术技术的修改，包括米勒的技术,Z-成形术,和V-Y成形术,自从最初提出传统的经典系切除术以来，已经建立起来，以应对与异常的唇系相关的困难。该病例报告表明，使用Z-成形术方法去除21岁女性患者的高乳头型唇缘附件，以及正畸治疗如何导致中线舒张闭合。出于几个原因,Z型成形术的全系切除术被证明是可靠的，并且对于去除异常的唇系连接产生了出色的美学效果。了解Z-成形术将实现基于主要意图的组织愈合，降低组织挛缩的风险，缩短病人的康复时间，并提高患者的美学效果。
