OBJECTIVE
This study aimed to evaluate the clinical effect of periodontal microscopic surgery on the augmentation of attached gingiva and determined the clinical principle on how to use minimally invasive surgery to improve the surgery success rate.
METHODS
Twenty patients with insufficient attached gingiva around implants were selected. Periodontal microscopic surgery for free gingival graft was performed to increase the width of the attached gingiva around the implants. The survival state of the free gingiva was observed after surgery, and the width of the attached gingiva around the implants was recorded before and after surgery and 1 year after surgery. The shrinkage rate of the free gingival flap 1 year after surgery was analyzed to evaluate the stability of the flap.
RESULTS: The flaps of the 20 cases all survived. One year after the operation, the width of the attached gingiva was (3.05±0.44) mm, which increased compared with that of preoperation (2.56±0.31) mm and decreased compared with that of postoperative day (2.13±0.28) mm. The shrinkage rate of the attached gingiva was 41.22%±5.04%.
CONCLUSIONS
The application of microscopic surgery on the augmentation surgery of attached gingiva can increase the success rate and improve the quality and quantity of attached gingiva around implants.
目的
本研究旨在评估牙周显微手术在附着龈增量中的临床效果，并确定如何运用微创手术提高手术成功率的临床原则。
方法
选取20例种植体周围附着龈不足的患者。采用牙周显微手术进行游离龈移植，以增加种植体周围附着龈的宽度。术后观察游离龈的存活状态，记录手术前后及术后1年种植体周围附着龈的宽度。分析术后1年游离龈瓣的收缩率，以评估瓣的稳定性。
结果
20例患者的瓣均存活。术后1年，附着龈宽度为（3.05±0.44）mm，较术前（2.56±0.31）mm增加，较术后当日（2.13±0.28）mm减小。附着龈收缩率为41.22%±5.04%。
结论
显微手术应用于附着龈增量手术可提高成功率，改善种植体周围附着龈的质量和数量。
