To compare implant treatment outcome after maxillary sinus membrane elevation with simultaneous installation of implants with or without the use of graft material applying the lateral window technique.
MEDLINE/PubMed, Cochrane Library, and Embase search in combination with a hand-search of relevant journals was conducted from January 1, 2004 to January 1, 2016.
Thirteen studies fulfilled the inclusion criteria. Survival of suprastructures has not been compared within the same study. Short-term implant survival without graft material varied between 96% and 100% compared to 100% for autogenous bone or bone substitutes. No significant difference in bone gain was reported without graft material compared to autogenous bone. The density of newly formed bone increased significantly during the observation period. Bone density was significantly higher in sinuses augmented with blood clot compared to bone substitute, whereas no significant difference was found when compared to autogenous bone. Noncomparative studies demonstrated high long-term implant survival and new bone formation after sinus membrane elevation without graft material.
Sinus membrane elevation without the use of a graft material seems to enhance new bone formation with high implant survival, but long-term comparative studies are missing.
比较经上颌窦提升术同期植入种植体与使用或不使用外侧壁开窗技术的移植物的种植体治疗效果。
对 2004 年 1 月 1 日至 2016 年 1 月 1 日期间 MEDLINE/PubMed、Cochrane 图书馆和 Embase 进行检索，并对相关杂志进行手工检索。
13 项研究符合纳入标准。同一研究中未比较上部结构的存活率。与自体骨或骨替代品的 100%相比，无移植物短期种植体存活率在 96%至 100%之间。无移植物组与自体骨组的骨增量无显著差异。在观察期间，新形成的骨密度显著增加。与骨替代品相比，有血凝块增强的窦内骨密度显著更高，而与自体骨相比则无显著差异。非对照研究表明，在不使用移植物的情况下进行窦膜提升后，长期种植体存活率和新骨形成较高。
在不使用移植物的情况下进行上颌窦提升术似乎可以促进新骨形成，并获得高种植体存活率，但目前仍缺乏长期的对照研究。
