    [摘要]目的：探讨种植联合游离龈移植术(Free gingival graft，FGG)修复牙列缺损伴软硬组织中重度缺损的临床疗效。方法：选取2019年5月-2020年5月笔者医院收治的62例牙列缺损伴软硬组织中重度缺损患者，根据手术方法不同将其分为对照组(n=31)和研究组(n=31)，对照组行种植联合根向复位瓣术(Apically positioned flap，APF)修复，研究组行种植联合FGG修复。比较两组角化齦宽度和厚度、口腔健康指标及临床疗效，记录两组修复后1年的不良反应发生情况。结果：术后6个月及术后1年，两组角化龈宽度、厚度均大于术前，且同时间段研究组角化龈宽度、厚度均大于对照组(P<0.05)；术后6个月，两组改良菌斑指数(modified plaque index，mPI)、改良出血指数(modified bleeding index，mBI)、探诊出血(Bleeding on probing，BOP)及探诊深度(Probing depth，PD)均低于术前，研究组BOP、PD均低于对照组(P<0.05)；术后1年，对照组BOP、PD均高于术后6个月，研究组BOP、PD低于对照组(P<0.05)；研究组治疗总有效率高于对照组(P<0.05)；两组不良反应总发生率比较差异无统计学意义(P>0.05)。结论：种植联合FGG修复牙列缺损伴软硬组织中重度缺损，能有效增加患者角化龈宽度和厚度，改善种植体周围软组织形态，有利于口腔卫生健康维护及增强种植体稳定性，安全性良好。

    Abstract： Objective? To investigate the clinical efficacy of implantation combined with free gingival grafting (FGG) in repairing dentition defects with moderate and severe soft and hard tissue defects. Methods? A total of 62 patients with dentition defects with moderate to severe defects of soft and hard tissues admitted to authors hospital from May 2019 to May 2020 were selected and divided into control group (n=31) and study group (n=31) according to different surgical methods. The control group underwent implantation combined with apically positioned flap (APF) repair ......
