Aim: Various techniques are practiced for evaluation of occlusal vertical dimension. And each of the method being practiced has its own restrictions. Various techniques are practiced for evaluation of occlusal vertical dimension in complete denture patients but, a fully precise method of determining the same is not present and each method that is being practiced has its own advantages and disadvantages. So, the objective of this study is to discover a relationship between occlusal vertical dimension and facial measurements. Materials and methods: A study was conducted on 100 dentulous subjects. Anthropometric measurements of occlusal vertical dimension were recorded clinically using digital Vernier caliper. Similarly, distance between other facial landmarks (inter pupillary distance & length of ear) were also recorded. Using person’s correlation, association was studied between the facial measurements and vertical dimension. Correlation coefficient (r)was obtained at the significant level ≤0.05 and confidence interval of 95% using Pearson’s correlation. A software namely statistical package for social sciences(SPSS) 22.0 version was used for the execution of regression command and prediction equations being prepared to estimate VDO. Results: VDO was significantly and positively correlated with all the parameters studied. Correlation of VDO was strongest for Interpupillary distance in males (r‑0.570) and least for length of ear in females (r‑0.319). The regression equation used to determine VDO got us a standard error of +2.2048 in male subjects and ±3.0179 in females for length of ear. Conclusion: The study was aimed to get an association between VDO and facial measurements. This was done to discover the prospect of another method which will be helpful to determine VDO in completely edentulous patients along with the routine methods commonly used. This study showed that these facial measurements can be extremely helpful in clinical assessment of occlusal vertical dimension.
