摘　　要：经牙槽嵴顶上颌窦提升术是牙种植临床中解决上颌后牙区骨高度不足的有效方法,但现行的骨凿法、剥离法、Smart钻法等都需要专门的手术工具盒。本文介绍了一种使用各个种植系统自带的扩孔钻去除窦底剩余骨并在种植体植入的过程中同时推起窦膜的上颌窦提升方法。本技术操作简便、省时、窦膜穿孔率低,对146人175颗种植体进行1年的随访观察,在3 mm≤剩余骨高度(RBH)<5 mm和5≤RBH<8 mm两种情况下分别增加了5.00 (4.70,5.30) mm和2.10 (1.40,2.70) mm的窦内骨高度,可以满足临床种植体的稳定性要求,是一项适宜推广的牙种植技术。Transcrestal maxillary sinus floor elevation is an effective method to solve the problem of insufficient bone height in the posterior maxillary region.However,current methods,such as osteotome sinus floor elevation,cushioned grind-out technique,Smart Drill technique,etc.,require specialized surgical tool boxes.In this article,we introduce a new method of transcrestal maxillary sinus elevation that uses built-in reamers of various implant systems to scrap residual bone at the sinus floor and uses the implant to push the sinus membrane during implant placement.This technique is easy to operate and time saving and has a low rate of sinus membrane perforation.After a one-year follow-up observation of 146 people and 175 implants,the endo-sinus bone gains were 5.00(4.70,5.30) mm and 2.10(1.40,2.70) mm in the group of 3 mm≤residual bone height(RBH) <5 mm and the group of 5 mm≤RBH<8 mm,respectively,which can meet the clinical requirements of implant stability.This technique is suitable in generalizing dental implantation.
