The primary goal of periodontal therapy is to restore the tooth supporting tissues lost due to periodontal disease. The aim of the present study was to compare the efficacy of combination of GTR membrane and alloplastc bone graft with open flap debridement (OFD) in treatment of periodontal intrabony defects.
Twenty paired intrabony defects were surgically treated using split mouth design. The defects were randomly assigned to treatment with OFD, GTR membrane+bone graft (test) or OFD alone (control). The clinical efficacy of two treatment modalities was evaluated at 6 months postoperatively by clinical, radiographical parameters. The measurements included probing pocket depth (PD), clinical attachment level (CAL), gingival recession (GR), bone fill (BF), bone density (BD).
The mean reduction in PD at 0 to 6 months was 3.20±0.82 mm and CAL gain of 3.10±1.51 mm occurred in the GTR membrane+bone graft (test) group; corresponding values for OFD (control) were 2.10±0.63 mm and 1.90±0.57 mm. Similar pattern of improvement was observed when radiographically postoperative evaluation was made. All improvement in different parameters was statistically significant (p<0.01).
Treatment with a combination of collagen membrane and bone graft led to a significantly more favorable clinical outcome in intrabony defects as compared to open flap debridement alone.
牙周治疗的主要目标是恢复因牙周疾病而丧失的牙齿支持组织。本研究的目的是比较引导组织再生(GTR)膜与异体骨移植联合开放瓣清创术(OFD)治疗牙周骨内缺损的疗效。
采用双侧对照设计对20对骨内缺损进行手术治疗。将缺损随机分为OFD治疗组、GTR膜+骨移植(试验组)或单纯OFD治疗组(对照组)。术后6个月通过临床和影像学参数评估两种治疗方式的临床疗效。测量指标包括探诊深度(PD)、临床附着水平(CAL)、牙龈退缩(GR)、骨填充(BF)、骨密度(BD)。
GTR膜+骨移植(试验组)在0至6个月时PD平均减少3.20±0.82mm,CAL增加3.10±1.51mm;OFD(对照组)的相应值分别为2.10±0.63mm和1.90±0.57mm。影像学术后评估也观察到类似的改善模式。不同参数的所有改善均具有统计学意义(p<0.01)。
与单纯开放瓣清创术相比,胶原膜和骨移植联合治疗在骨内缺损方面导致了明显更有利的临床结果。
