Abstract

This study compared the accuracy of linear measurements of the alveolar ridge in images obtained using 64-detector-multislice computed tomography (CT) and cone beam CT (CBCT). Eight sites were selected corresponding to the regions of molars, premolars, canines, and incisors in six dry human jaws. After the completion of multislice CT and CBCT, the jaws were sectioned into specific regions. Results showed there was no statistically significant difference between the measurements obtained from the CT images and those obtained from dry jaws (actual measurements) for all the evaluated sites (molars, premolars, and anterior teeth). There was also no statistically significant difference between the measurements obtained by the two CT methods.

摘要

本研究比较了使用64层螺旋计算机断层扫描（CT）和锥形束CT（CBCT）获得的图像中牙槽嵴线性测量的准确性。在六个干燥的人类颌骨中，选择了与磨牙、前磨牙、尖牙和切牙区域相对应的八个部位。完成多层CT和CBCT扫描后，将颌骨切成特定区域。结果显示，对于所有评估部位（磨牙、前磨牙和前牙），从CT图像获得的测量值与从干燥颌骨获得的测量值（实际测量值）之间没有统计学上的显著差异。两种CT方法获得的测量值之间也没有统计学上的显著差异。
