Staged sinus floor elevation allows predictable implant placement in the severely deficient posterior maxilla. An alternative to the most commonly used lateral window approach involves the apical displacement of crestal core(s) using osteotomes and a composite graft. Crestal core elevation (CCE) incorporates specially designed osteotomes to minimize the incidence of membrane perforation and placement of a barrier membrane over the core osteotomy. This article presents the technique and instrumentation, as well as documentation of 43 patients demonstrating the efficacy of this modality.
分期式上颌窦底提升术可实现严重骨量不足的上颌后牙区种植体的可预测性植入。一种替代最常用的侧窗入路的方法是使用骨凿和复合移植物进行嵴顶骨块的根尖移位。嵴顶骨块提升术（CCE）采用专门设计的骨凿，以尽量减少膜穿孔的发生率，并在骨块截骨处上方放置屏障膜。本文介绍了该技术和器械，并记录了43例患者以证明该方法的有效性。
