本研究是一项随机对照研究，旨在评估游离龈移植(FGGs)修复种植体周围角化龈(KM)<2mm后18个月的临床效果。

本研究是一项随机对照研究，旨在评估游离龈移植(FGGs)修复种植体周围角化龈(KM)<2mm后18个月的临床效果。

获取FGG组18个种植体（11个患者）和对照组8个种植体（7个患者）术后48个月的随访数据。对照组中的8个种植体在18个月后进行了FGGs，构成延迟FGG组（5个患者）。检测Km宽度、牙龈退缩(MR)和骨水平(CBL)。

结果发现，FGG组中Km宽度增加和MR降低保持了48个月，且MR值较非手术组低。在48个月内，非手术组的骨吸收（0.4±0.4mm）明显高于FGG组（0±0.4mm）。与FGG前相比，延迟FGG组MR降低，CBL没有显着差异。

因此，FGGs可能是一种修复种植体周围KM不足的实用方法。
