目的 观察双抗胶原膜应用于引导组织再生(guided tissue regeneration,GTR)的长期疗效,以期为临床提供参考.方法 对24例重度牙周炎患者的26颗患牙按单双数法随机分组,分别应用双抗胶原膜(试验组)和牛腱胶原膜(对照组)对3l处垂直型骨吸收和根分叉病变进行GTB治疗,试验组共13例患者,14颗患牙,16处骨缺损;对照组共11例患者,12颗患牙,15处骨缺损.分别于术前、术后6个月、1、3和6年进行临床附着水平、计算机辅助密度影像分析(computer assisted densitometry image analysis,CADIA)等指标的临床检查,并对结果进行统计学分析.结果 GTR术后1年,试验组临床附着获得是(3.93±1.74)mm,对照组是(2.25±1.90)mm(t=2.146,P=0.044),CADIA值分别增加(53.14±21.35)和(32.96±17.97)(t=2.319,P=0.031).GTR术后6年与术后1年临床附着水平相比,试验组和对照组仅分别平均有0.35 mm和0.34 mm的附着丧失.结论 在6年随访的病例中,双抗胶原膜应用于引导组织再生所获得的再生牙周组织可以长期保持稳定.

Objective To evaluate the long-term clinical effect of dual anti-collagen membranes in guided tissue regeneration(GTR). Methods This randomized clinical trial included 26 teeth in 24 patients, presenting a total of 31 lesions consisting of intrabony defects and furcation defects. Twenty-six teeth were divided into two groups and treated by GTR with dual anti-collagen membranes and atelocollagen membranes, respectively. At baseline, 6 months, 1, 3 and 6 years, the following parameters were recorded; clinical attachment level, probing depth, gingival recession and the quantity of alveolar bone analyzed by computer assisted densitometry image analysis (CADIA). Results At 1 year after GTR surgery, the gain of clinical attachment in dual anti-collagen membranes group was (3. 93 ± 1. 74) mm,compared with (2. 25 ± 1. 90) mm in atelocollagen group(P =0. 044). The increasing of the value of CADIA in dual anti-collagen membrane and atelocollagen group were (53. 14 ± 21. 35) and (32. 96 ± 17. 97 ), P = 0. 031. At 3 and 6 years, clinical parameters remained basically stable in both groups, compared to that at 1 year after surgery. Conclusions The regeneration of periodontal tissues obtained by GTR with dual anti-collagen membranes could be maintained on a long-term basis.
