A variety of materials and procedures are used to create adequate bone volume in the maxillary sinus for placement of endosseous implants in the posterior atrophic maxilla. This review used the structured method of meta-analysis to evaluate the survival of the implants placed into various materials that have been used in the maxillary sinus with the sinus lift procedure. A MEDLINE computer search of the English literature yielded 28 studies that reported using the maxillary sinus augmentation procedure to increase bone volume for placement of endosseous implants; only 10 of these met the inclusion criteria for meta-analysis. Data regarding immediate or delayed placement of implants were combined to simplify analysis. Implant survival was 90% for autogenous bone (484 implants in 130 patients followed for 6 to 60 months), 94% for the combination of hydroxyapatite (HA) and autogenous bone (363 implants in 104 patients followed for 18 months), 98% for the combination of demineralized freeze-dried bone (DFDB) and HA (215 implants in 50 patients followed for 7 to 60 months), and 87% for HA alone (30 implants in 11 patients followed for 18 months). The results for autogenous bone were based on six reports, for the combination of autogenous bone and HA on three reports, and for DFDB/HA and HA alone on one study each. The results of single studies cannot be weighted as heavily as the results combining several studies; however, the analysis of these studies suggests that implant survival rates were similar for autogenous bone, HA/autogenous bone mix, HA/DFDB, and HA alone.
在上颌后牙区牙槽骨萎缩的情况下,为植入骨内种植体,人们采用了多种材料和方法来在上颌窦内形成足够的骨量。本综述采用Meta分析的结构化方法,评估通过上颌窦提升术植入上颌窦内不同材料的种植体的存留率。通过MEDLINE计算机检索英文文献,共找到28项报道使用上颌窦增量术增加骨量以植入骨内种植体的研究;其中只有10项符合Meta分析的纳入标准。将关于种植体即刻或延期植入的数据合并,以简化分析。自体骨组的种植体存留率为90%(130例患者的484枚种植体,随访6至60个月),羟基磷灰石(HA)与自体骨联合组为94%(104例患者的363枚种植体,随访18个月),脱矿冻干骨(DFDB)与HA联合组为98%(50例患者的215枚种植体,随访7至60个月),单纯HA组为87%(11例患者的30枚种植体,随访18个月)。自体骨组的结果基于6篇报道,自体骨与HA联合组基于3篇报道,DFDB/HA组和单纯HA组各基于1项研究。单项研究的结果权重不如多项研究合并后的结果;然而,对这些研究的分析表明,自体骨、HA/自体骨混合物、HA/DFDB和单纯HA的种植体存留率相似。
