To compare the mesiodistal space measurements of single-implant sites on panoramic and oblique images generated by cone-beam CT (CBCT).
CBCT images for 101 single-implant sites of 66 patients referred for pre-surgical radiographic implant planning were selected for the study; 15-mm-thickness panoramic images were reformatted and used for measuring mesiodistal space dimensions. The measurements were repeated and compared with those of thin oblique images (200-300 μ) using Wilcoxon signed rank test. The correlation between measurements in addition to intra-observer agreement was evaluated by Pearson's correlation coefficients.
All mesiodistal space measurements on panoramic and oblique images generated by CBCT were strongly correlated and there were no statistically significant differences between them (P < 0.05).
Both panoramic and oblique images generated by CBCT can be used for measuring mesiodistal space dimensions of single-implant sites.
比较锥形束CT（CBCT）生成的全景图像和斜位图像上单个种植位点的近远中空间测量值。
选取66例因种植术前影像学种植规划而转诊患者的101个单个种植位点的CBCT图像用于研究；重新格式化15毫米厚的全景图像并用于测量近远中空间尺寸。测量重复进行，并使用Wilcoxon符号秩检验与薄斜位图像（200 - 300μ）的测量值进行比较。通过Pearson相关系数评估测量值之间的相关性以及观察者内一致性。
CBCT生成的全景图像和斜位图像上所有近远中空间测量值均高度相关，且它们之间无统计学显著差异（P < 0.05）。
CBCT生成的全景图像和斜位图像均可用于测量单个种植位点的近远中空间尺寸。
