Abstract: 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.
