Abstract: Implant-supported dentures have become a crucial modality for restoring missing teeth. With the advancement of societal living standards，individuals′expectations for implantation extend beyond mere tooth replacement to encompassing higher aesthetic demands on soft tissues. Following tooth loss，both the soft and hard tissues in the edentulous area undergo a series of changes. Attached gingiva plays a pivotal role in safeguarding periodontal health. Insufficient attached gingiva can compromise the implant′s resistance against external stimuli and potentially result in implant failure under severe circumstances. Attached gingiva augmentation is frequently employed to address issues related to inadequate attached gingiva；however，this procedure may also give rise to certain complications that impact its success rate. This article aims to elucidate potential complications arising from attached gingiva augmentation during implant restoration and provide recommendations on their management and prevention，thereby offering valuable insights for clinical practice.

摘要： 种植义齿目前已成为修复缺失牙的重要手段。随着社会生活水平的提高，人们对于种植的要求已不仅局限于恢复缺失牙，对于软组织的美学要求也越来越高。牙齿缺失后，缺牙区软硬组织会发生一系列的变化。附着龈作为保护牙周健康的重要组织，缺乏时会影响种植体对外界刺激的抵抗力，严重者可导致种植失败。临床上常通过附着龈增宽术来解决附着龈不足等问题，但手术同时也存在一些并发症影响附着龈增宽术的成功率。文章将对种植修复过程中附着龈增宽术可能产生的并发症以及如何处理和预防进行描述，为临床工作提供一些建议。
