摘　　要：目的 :探索上颌窦底形态及其骨嵴分布的冠状位及矢状位锥形束CT(CBCT)影像表现。方法 :收集涉及上颌窦的CBCT资料,分析上颌窦底形态及其骨嵴分布。结果 :右侧上颌第一、二前磨牙牙位上颌窦底矢状位形态分别主要为斜形型、平坦型,分别占55.80%、53.40%,冠状位形态均主要为凹面型,分别占84.80%、61.30%;右侧上颌第一、二磨牙牙位上颌窦底矢状位形态均主要为平坦型,分别占74.90%、69.80%,冠状位形态均主要为平坦型,分别占61.40%、64.30%;左侧上颌第一、二前磨牙牙位上颌窦底矢状位形态分别主要为斜形型、平坦型,分别占52.60%、53.60%,冠状位形态均主要为凹面型,分别占71.90%、50.30%;左侧上颌第一、二磨牙牙位上颌窦底矢状位形态均主要为平坦型,分别占77.20%、67.50%,冠状位形态均主要为平坦型,分别占58.70%、64.90%。骨嵴出现率为33.44%。结论 :本研究测量了各个牙位上颌窦底形态及其骨嵴分布情况,为上颌窦底提升术操作提供参考依据。Objective:To analyze the morphology of maxillary sinus floor and the location of maxillary sinus septa in cone-beam CT(CBCT)on coronal and sagittal orientations.Methods:The morphology of maxillary sinus floor and the location of maxillary sinus septa were collected and analyzed in CBCT.Results:Most of the morphology of maxillary sinus floor were slope type and flat type for the right maxillary first and second premolar region in a sagittal orientation(55.80%,53.40%)and concave type for those oriented coronally(84.80%,61.30%).Most of the morphology of maxillary sinus floor was flat type for the right maxillary first and second molar region in a sagittal orientation(74.90%,69.80%)and flat type for those oriented coronally(61.40%,64.30%).Most of the morphology of maxillary sinus floor were slope type and flat type for the left maxillary first and second premolar region in a sagittal orientation(52.60%,53.60%)and concave type for those oriented coronally(71.90%,50.30%).Most of the morphology of maxillary sinus floor was flat type for the left maxillary first and second molar region in a sagittal orientation(77.20%,67.50%)and flat type for those oriented transversely(58.70%,64.90%).Maxillary sinus septa were found in 33.44%of patients.Conclusions:The morphology of maxillary sinus floor and the location of maxillary sinus septa were measured and provide a reference for the maxillary sinus elevation procedures.
