[摘 要]目的 观察游离龈移植术(FGG)对牙龈瘤切除术后软组织缺损的修复效果。方法 选取2021年3月-2023年3月于南充市中心医院接受治疗的牙龈瘤患者40例，随机分为对照组和观察组，每组20例。对照组予以冠向复位瓣术(CAF)，观察组予以FGG，比较两组术后1周疼痛程度、术后3个月角化龈宽度(KGW)、术后1周出血指数(BI)、术后3个月牙龈形态美学效果。结果 两组VAS评分、BI比较，差异无统计学意义(P>0.05)；观察组KGW高于对照组，牙龈形态美学效果优于对照组(P<0.05)。结论FGG和CAF均能修复牙龈瘤切除术后软组织缺损，但FGG所恢复牙龈形态效果更好，技术敏感性更高，若患者角化龈宽度较小，则可选择FGG进行修复。
