目的：通过头影测量的方法，对30例正常人群颅面部硬组织标志点进行分析，寻找一种更加精确量化的方法来评估咬合垂直距离。方法选择30名年龄在20~30岁的正常人群进行头影测量分析。采用Winceph 8.0测量软件进行描点和测量。结果面中心角（CA）与面下角（LA）均值分布差异无统计学意义（t=-1.490，P=0.147）。CA角和LA角之间存在显著线性相关（r=0.976，P=0.000），得出回归方程为y=0.298+0.997x。结论可以通过CA角对咬合垂直距离进行评估量化，并且可以通过CA角来指导临床确定咬合垂直距离。

Objective This study aims to identify highly accurate quantitative methods for evaluating the occlusal vertical dimension by using cephalometric radiographs to analyze the craniofacial hard tissue landmarks in 30 cases with normal occlusions. Methods A total of 30 subjects with normal occlusions and aged between 20 and 30 years old were included in the study. Cephalometric radiographs were obtained and analyzed using the Winceph 8.0 measurement software. Landmark points were identified and measured. Results The mean distribution difference of the center angle (CA) and lower angle (LA) of the face was not statistically significant (t=-1.490, P=0.147). The CA and LA had a significantly linear correlation (r=0.976, P=0.000), and the regression equation was y=0.298+0.997x. Conclusion The CA can be used to assess and quan-tify the occlusal vertical dimension in clinical practice.
