Background: Accurate recording of occlusal vertical dimension in edentulous patients is always a prime consideration for an operator but subjective in nature and depends on esthetics and phonetics. Although there are many techniques used for recording vertical dimension at occlusion; still, there is no objective reference point against which, the recorded OVD can be verified.
Aim: The aim of this study was to correlate the vertical dimension of occlusion with accepted anatomical facial landmarks and digit measurements in dentulous subjects.
Objectives: To derive a correlation between OVD and demographics (Age and gender); to validate specific facial and digit measurements which can be used to verify the recorded OVD.
Study design : Cross sectional study
Materials and Methods: 51 adult dentulous volunteers were selected for the study. Various facial and digit measurements were recorded and the correlation between OVD and these measurements was checked using independent sample t test. The correlation was analysed using Pearson’s method
Null hypothesis: There is no correlation between Vertical dimension of occlusion (OVD) and facial or digit measurements.
Results: The Pearson’s product moment correlation coefficient was determined. Among the digit measurements, OVD was significantly (p-value<0 r=0.662 r=0.509;> Among the facial measurements, OVD was significantly (p-value<0 r=0.854 r=0.728 r=0.709> Conclusion: Various facial and finger measurements can be utilised as adjuncts for the estimation and verification of occlusal vertical dimension.
