Abstract: Objective: Establishment of proper occlusal vertical dimension (OVD) is one of the important challenges for successful prosthodontic therapy. No methods are considered to be scientifically accurate in determining the original OVD. The aim of the current anthropometric study was to evaluate the correlation between the OVD, length of the thumb and facial landmarks in a sample of Iranian students.

Materials and Methods: This study was conducted on 200 dentate subjects selected both males and females with the mean age 24.91±5.85 years. The OVD, thumb length (TL), distance from the Rima oris to the pupil of the eye (RO- Pu) and distance from the Nasal alar to the tragus of the Ear (N-E) were measured to correlate with OVD.

Results: Statistically significant correlations were observed between OVD and studied parameters in total samples. Also there was a positive correlation between OVD and RO- Pu in both groups.

Conclusion: We can conclude that RO-Pu distance can be more reliable method than others landmarks for predicting the OVD.
