Observational analysis found significant bilateral symmetry and biometric measurement for occlusal vertical dimension in complete dentition.
A cross-sectional clinical evaluation was conducted on 210 adult dental students with complete dentition, healthy periodontium, and bilateral molar Class I relationship. The mean intercanine distance was 16.7 mm on the right side and 16.9 mm on the left side, demonstrating strong bilateral symmetry (correlation coefficient = 0.859; p < 0.001). Male participants had significantly higher measurements than females, with mean differences of approximately 1.15 mm, while no significant differences were observed across age groups. The overall mean value of 16.8 mm supports the clinical validity of this biometric measurement as a stable and accessible anatomical reference for determining occlusal vertical dimension in similar populations.
