Excessive pneumatization of the maxillary sinus subsequent to the loss of teeth frequently interferes with the placement of osseointegrated implants. Many techniques have been developed and tested to reduce the size and alter the anatomy of the sinus to augment the quantity of bone available for an adequate number of prosthetically well-placed implants of a satisfactory length. Most of these describe extensive one- or two-stage sinus grafting procedures that are usually performed through a lateral approach. A technique of localized elevation of the maxillary sinus floor through a less-invasive crestal approach is presented here. Ninety-seven implants were placed with this technique between 1991 and 1998. The healing was always uneventful, without any sign of pathologic reaction in the maxillary sinus. Eighty-six implants were successfully loaded for a period between 6 and 90 months (mean 35 months). Eight implants failed to integrate, and three were lost after different periods of function, for a cumulative success rate of 88.6%.
牙齿缺失后上颌窦过度气化常常会干扰骨结合种植体的植入。人们已经研发并测试了多种技术来减小上颌窦的大小并改变其解剖结构，以增加可用于植入足够数量、位置合适且长度满意的修复性种植体的骨量。其中大多数技术描述的是广泛的一期或二期窦底植骨手术，通常通过外侧入路进行。本文介绍一种通过微创牙槽嵴入路对上颌窦底进行局部提升的技术。1991年至1998年间，使用该技术植入了97枚种植体。愈合过程均顺利，上颌窦未出现任何病理反应迹象。86枚种植体成功负重6至90个月（平均35个月）。8枚种植体未能成功骨结合，3枚在不同功能期后丢失，累积成功率为88.6%。
