In 31 patients we implanted a teflon membrane (Gore-Tex) during flap operation for a duration of 6 weeks. The periodontal situation was assessed clinically and radiographically 1-1.5 years after surgery. The study comprised 18 upper and lower molars with furcation involvement and 15 single-rooted teeth with a 2-wall-, 3-wall- or combined bony defect. Clinical gain of attachment only occurred in furcation class II lesions (upper molars + 2.3 mm, lower molars + 2.5 mm), whereas the attachment level was unchanged in "through and through" furcation defects in the upper jaw and loss of attachment was observed at lower molars with class III furcations. In single-rooted teeth the gain of attachment varied between 0.5 and 8.5 mm, depending on the proportions of the defect and the number of the surrounding bony walls.
我们对31例患者在皮瓣手术期间植入了聚四氟乙烯膜（戈尔特斯），持续6周。术后1至1.5年对牙周情况进行了临床和影像学评估。该研究包括18颗有根分叉病变的上下磨牙以及15颗有两壁、三壁或混合性骨缺损的单根牙。附着水平的临床改善仅发生在Ⅱ度根分叉病变中（上颌磨牙增加2.3毫米，下颌磨牙增加2.5毫米），而上颌“贯通性”根分叉缺损的附着水平无变化，Ⅲ度根分叉的下颌磨牙出现附着丧失。在单根牙中，附着增加在0.5至8.5毫米之间，具体取决于缺损比例和周围骨壁数量。
