上颌后牙缺失患者上颌窦影像学特征分析

目的：分析上颌后牙缺失患者的上颌窦影像学特征,探讨不同类型上颌后牙缺失患者上颌窦影像学的变化特点。方法：选取上颌后牙缺失患者的700份数字化X线曲面断层片作为研究资料。调查上颌窦分隔和上颌窦囊肿的发生率并根据患者的性别,年龄及缺牙状况进行分组,测量各组缺牙区的窦嵴距及窦底高度,使用SPSS16.0软件对数据进行统计学分析。结果：单牙缺失组窦嵴距〉多牙缺失组窦嵴距,两组之间差异有显著性（P〈0.001）。多牙缺失组窦底高度〉单牙缺失组窦底高度,两组之间差异有显著性（P=0.014）。59岁～77岁组女性窦嵴距〈男性窦嵴距,男性窦低高度〈女性窦低高度,组内比较有显著差异（P〈0.001）。上颌窦分隔发生率为27%,上颌窦囊肿发生率为4.9%。结论：上颌后牙缺失不同缺牙状况窦底高度和窦嵴距有统计学差异,59～77岁年龄段窦底高度和窦嵴距有性别差异。

The imaging analysis of maxillary sinus with maxillary posterior teeth missing

Objective:To analysis the imaging features of maxillary sinus with maxillary posterior teeth missing,investigate the significance of maxillary sinus imaging change characteristics with different types of maxillary posterior teeth missing in patients. Method:A total of 700 digital panoramic radiographs were selected as research data,investigated the incidence of maxillary sinus septa and mucous retention cyst. grouped the digital panoramic radiographs according to patient's sex,age and tooth missing status.T...
