Gingival recession accounts for apical migration of the gingival margin, resulting in exposure of the cementoenamel junction and root surface, with exposure of the root surface linked to deteriorated esthetic appearance and increased dentinal hypersensitivity. Various surgical techniques have been used to correct labial gingival recession defects. The present study evaluated and compared the results of semilunar coronally positioned flap (SCPF) alone and in conjunction with free gingival graft (FGG) for the treatment of Miller Class I and II gingival recession defects in maxillary anterior teeth. A total of 20 bilateral Miller Class I and II gingival recession sites were included and randomly allocated (n = 10 sites/group) to either the semilunar coronally positioned flap technique alone (SCPF group; control) or with FGG (SCPF+FGG group; test). Longitudinal alterations in probing depth (PD), recession width (RW), recession height (RH), width of keratinized tissue (WKT), and clinical attachment level (CAL) were measured and analyzed for both groups at 1-, 3-, 6-, and 12-month follow-ups. Both groups saw a significant decrease in RH, RW, and CAL and a significant increase in WKT. No statistically significant difference was observed in the final root coverage outcome between both groups in terms of RH, RW, and CAL, but a significant increase in WKT was seen with SCPF+FGG. Both techniques demonstrated optimal results without significant differences in the final root coverage outcomes except for WKT, which had a statistically significant increase in the SCPF+FGG group.
牙龈退缩导致牙龈边缘向根尖方向移动,导致牙骨质-釉质界和牙根表面暴露,而牙根表面暴露则与美观恶化和牙本质敏感性增加有关。已经使用了各种手术技术来纠正唇侧牙龈退缩缺陷。本研究评估并比较了单独使用半月形冠向瓣(SCPF)和结合游离龈瓣移植(FGG)治疗上颌前牙 Miller Ⅰ类和Ⅱ类牙龈退缩缺陷的效果。共纳入 20 个双侧 Miller Ⅰ类和Ⅱ类牙龈退缩位点,并随机分配(n = 10 个位点/组)至单独使用半月形冠向瓣技术(SCPF 组;对照组)或结合游离龈瓣移植(SCPF+FGG 组;实验组)。在 1、3、6 和 12 个月的随访中,测量并分析了两组探诊深度(PD)、退缩宽度(RW)、退缩高度(RH)、角化组织宽度(WKT)和临床附着水平(CAL)的纵向变化。两组的 RH、RW 和 CAL 均显著降低,WKT 显著增加。两组最终的根面覆盖率结果在 RH、RW 和 CAL 方面没有统计学差异,但 SCPF+FGG 组的 WKT 显著增加。两种技术均表现出最佳效果,最终的根面覆盖率结果没有显著差异,除了 WKT 在 SCPF+FGG 组有统计学意义的增加。
