The management of furcation defects remains a challenge in periodontal therapy, Traditionally, furcation therapy involved scaling, rootplaning, furcation plasty and resective techniques. The purpose of this study was to clinically evaluate the potential of guided tissue regeneration in the treatment of mandibular molar grade II furcations using a nonresorbable barrier, TefGen-GTR and compare it with open flap debridement alone. Ten patients with similar bilateral grade II furcation lesions participated in the study. TefGen-GTR was placed in the experimental sites while the contralateral sites served as controls. Treatment effects were evaluated at six months reentry. Both groups showed gain in vertical and horizontal open probing attachment and defect depth reduction when compared to baseline values, with experimental sites showing statistically significant improvement over the controls. The results suggest that the nonresorbable Teflon barrier, TefGen-GTR, may be used as an alternative for treatment of grade II furcation invasions.
根分叉病变的治疗在牙周治疗中仍然是一项挑战。传统上，根分叉治疗包括刮治、根面平整、根分叉成形术和切除技术。本研究的目的是临床评估使用不可吸收屏障TefGen-GTR治疗下颌磨牙II度根分叉病变的潜力，并将其与单纯开放瓣清创术进行比较。10例双侧II度根分叉病变相似的患者参与了该研究。TefGen-GTR放置在试验部位，而对侧部位作为对照。在六个月再次手术时评估治疗效果。与基线值相比，两组的垂直和水平探诊附着均有增加，缺损深度减小，试验部位显示出比对照组有统计学意义的改善。结果表明，不可吸收的聚四氟乙烯屏障TefGen-GTR可作为治疗II度根分叉侵入的替代方法。
