A modification of the papilla preservation technique has been applied to achieve primary closure of the interproximal tissue over barrier membranes placed coronal to the alveolar crest. Fifteen patients with deep intrabony interproximal defects were treated. Defects had a probing attachment level loss of 9.9 +/- 3.2 mm and a recession of the gingival margin of 1.7 +/- 1.6 mm. The depth of the intrabony component was 5.5 +/- 2.9 mm; while the suprabony component was 5.9 +/- 2.0 mm. Titanium-reinforced teflon membranes were placed 1.3 +/- 0.7 mm from the cemento-enamel junction, 4.5 +/- 1.6 mm coronal to the interproximal alveolar bone crest. Primary closure over the interproximal portion of the membrane was obtained in 93% of cases. In 73% of the cases complete coverage of the membrane was maintained until its removal at 6 weeks. These data indicate that the modified papilla preservation technique can be successfully applied to obtain primary closure of the interdental space in regenerative procedures with barrier membranes.
乳头保留技术的一种改良方法已被应用于在牙槽嵴冠方放置的屏障膜上实现邻间隙组织的一期关闭。对15例患有深部骨内邻间隙缺损的患者进行了治疗。缺损的探诊附着丧失为9.9±3.2mm，牙龈缘退缩为1.7±1.6mm。骨内部分的深度为5.5±2.9mm；而骨上部分为5.9±2.0mm。钛增强聚四氟乙烯膜放置在距牙骨质-釉质界1.3±0.7mm处，在邻间牙槽嵴冠方4.5±1.6mm处。93%的病例实现了膜邻间部分的一期关闭。73%的病例在6周取出膜之前维持了膜的完全覆盖。这些数据表明，改良的乳头保留技术可成功应用于屏障膜再生手术中获得牙间隙的一期关闭。
