摘要
上颌窦底提升是增加上颌后牙区种植垂直骨量的主要方法之一.穿牙槽嵴上颌窦底提升(上颌窦底内提升)相比于侧壁开窗上颌窦底提升(上颌窦底外提升)具有安全、微创以及经济等优点.上颌窦的解剖形态是影响上颌窦底内提升术手术操作的重要因素之一.该文对上颌窦底形态、窦底剩余牙槽骨、上颌窦间隔以及施耐德膜等主要解剖因素进行综述分析,以期为临床工作中上颌窦底内提升的应用提供帮助.
Abstract
Maxillary sinus floor elevation is one of the main methods to increase the vertical bone volume for implants in the maxillary posterior region.According to the surgical approach,it can be divided into two surgical procedures:external sinus floor elevation and internal sinus floor elevation.The latter has the advantages of safety,minimally invasiveness,and economy compared with the former.The anatomical morphology of the maxillary sinus is one of the important factors affecting the operation of maxillary sinus floor elevation.This article reviews and analyzes the main anatomical factors such as the morphology of the maxillary sinus floor,the residual bone height,the maxillary sinus septum,and the Schneiderian membrane,in order to help the application of internal sinus floor elevation in clinical work.
