Prognosis in the management of Millers Class III or IV gingival recession is often fair to poor, which is further decreased by factors such as inadequate keratinized gingiva. Very few modalities show long-term success in the management of gingival recession with inadequate keratinized gingiva, free gingival graft (FGG) being one such technique.
Ten individuals with Millers Class III or IV recession and inadequate keratinized gingiva were recruited for the study. The first surgical procedure involved the FGG procedure to increase the width of keratinized gingiva (WOKG). Patients were recalled after 3 months for the second surgical procedure, where the flap was coronally advanced. They were recalled 9 months after the second surgery. WOKG was examined at baseline and 3 months (before the second surgical procedure). Recession depth (RD) and clinical attachment level (CAL) was examined at baseline, at 3 months (before the second surgical procedure) and at 12 months (9 months after the second surgical procedure). The percentage of root coverage was measured at 12 months from baseline.
Significant increase in WOKG was seen at 3 months. Significant decrease in RD and CAL was observed at 12 months from baseline. The percentage of root coverage was 76.4%.
Two-stage FGG procedure can be a successful modality in the management of Millers Class III or IV recession with inadequate keratinized gingiva. This technique improves the prognosis of such compromised cases.
米勒氏III级或IV级牙龈退缩的治疗预后通常为一般至较差,而诸如角化龈不足等因素会使其进一步恶化。在治疗角化龈不足的牙龈退缩方面,很少有方法能取得长期成功,游离龈瓣移植术(FGG)就是其中一种技术。
招募了10名患有米勒氏III级或IV级退缩且角化龈不足的个体参与研究。首次外科手术采用FGG手术以增加角化龈宽度(WOKG)。3个月后对患者进行复诊以进行第二次外科手术,即瓣向冠方推进。在第二次手术后9个月对他们进行复诊。在基线时以及3个月时(第二次外科手术前)检查WOKG。在基线时、3个月时(第二次外科手术前)以及12个月时(第二次外科手术后9个月)检查退缩深度(RD)和临床附着水平(CAL)。从基线开始在12个月时测量牙根覆盖百分比。
在3个月时可见WOKG显著增加。在基线后12个月时观察到RD和CAL显著降低。牙根覆盖百分比为76.4%。
两阶段FGG手术可以是治疗角化龈不足的米勒氏III级或IV级退缩的一种成功方法。该技术改善了此类复杂病例的预后。
