将12个10 MM植入物置于犬的即刻拔牙窝中。 用PTFE膜隔离6个植入物，6个部位作为对照。 在试验和对照部位进行标准化临床测量。 在18周时，将狗麻醉并铺上皮瓣以获得临床测量结果。 增强种植体周围的平均骨增量为2.6 mm，而对照部位的平均骨增量为1.0 mm。增强部位附近的牙槽嵴宽度增加了1.2 mm，对照部位的宽度增加了0.6 mm。测试和对照样本的组织学评价显示增强种植体周围的骨形成更大。 与对照组相比，PTFE膜增强的植入物具有临床显著的骨再生量。
TWELVE 10 MM IMPLANTS WERE placed into immediate extraction sockets in dogs. Six implants were isolated with PTFE membranes and 6 sites served as controls. Standardized clinical measurements were taken at test and control sites. At 18 weeks the dogs were anesthetized and flaps were laid for the purpose of obtaining clinical measurements. The average gain of bone around augmented implants was 2.6 mm, while control sites had an average bone gain of 1.0 mm. Ridge width adjacent to augmented sites increased by 1.2 mm and control sites had an increased width of 0.6 mm. Histologic evaluation of test and control specimens showed greater bone formation around augmented implants. Implants augmented with PTFE membranes had clinically significant amounts of bone regeneration when compared with controls.
