The purpose of the present study, which used anorganic bovine bone (Bio-Oss) with and without autogenous bone as the augmentation material, was to compare the results of sinus elevation performed without a membrane (control) with the results of sinus elevation performed with either a short-term bioabsorbable membrane (Bio-Gide) or a nonabsorbable membrane (Gore-Tex) with regard to both vital bone formation and implant survival. Sinus lifts were performed on 51 patients (38 unilateral, 13 bilateral) with the delayed placement of 135 implants. Histomorphometric data were obtained at the time of implant placement, 6 to 10 months following the grafting procedure. Vital bone formation was 17.6%, 16.9%, and 12.1%, respectively, for the Bio-Gide, Gore-Tex, and no membrane groups. Of the 135 implants placed there were 3 failures (2 Bio-Gide, 1 Gore-Tex). There was no significant difference between the membrane groups as to vital bone formation and implant survival.
本研究的目的是比较不使用膜（对照）进行上颌窦提升的结果与使用短期生物可吸收膜（Bio-Gide）或不可吸收膜（Gore-Tex）进行上颌窦提升在重要骨形成和种植体存活方面的结果，该研究使用有机牛骨（Bio-Oss）加或不加自体骨作为增量材料。对51例患者（38例单侧，13例双侧）进行了上颌窦提升，并延迟植入135颗种植体。在植入种植体时、植骨手术后6至10个月获取组织形态计量学数据。Bio-Gide组、Gore-Tex组和无膜组的重要骨形成率分别为17.6%、16.9%和12.1%。在植入的135颗种植体中，有3颗失败（2颗Bio-Gide，1颗Gore-Tex）。在重要骨形成和种植体存活方面，膜组之间没有显著差异。
