美学区连续多颗牙缺失植入位点的CBCT测量分析研究
|
Abstract:
摘要 目的: 通过锥形束CT( cone beam computed tomography,CBCT) 测量研究美学区连续多颗牙缺失的植入位点,为临床医师提供相应的参考依据。方法: 从青岛市市立医院口腔医学中心就诊的患者中,筛选出50例患者的CBCT资料。应用CBCT配套软件对植入位点进行测量分析,并提取相关数据,采用SPSS24.0进行统计学分析。测量距离为两邻牙釉牙骨质界中点的连线至植体中心的距离。结果: CBCT测量数据显示如下,2颗中切牙缺失时,左上中切牙测量值(4.24±0.90) mm,右上中切牙测量值(4.10±0.86) mm;含侧切牙在内的2颗前牙缺失时,左上尖牙测量值(5.72±0.72) mm,左上中切牙测量值(5.10±0.73) mm,右上中切牙测量值(5.50±0.77) mm,右上尖牙测量值(4.91±0.97) mm。结论: 运用CBCT测量分析美学区多颗牙连续缺失即刻植入位点所得数据,可为即刻种植理想植入位点提供理论依据
