Comparison of Face Anthropometry and Digital 2D-Face Photogrammetry as Methods for Predicting Vertical Dimension of Occlusion.

This article focuses on comparing face anthropometry and digital 2D-face photogrammetry as methods for predicting the occlusal vertical dimension (OVD) in a Serbian adult population. The study measured 15 craniofacial linear distances in 90 adults using both direct anthropometric tools and digital photogrammetric analysis via the Dr Ceph software, finding no statistically significant differences between the two methods. Multivariate regression identified that OVD (measured as the distance between subnasale and gnathion, Sn-Gn) significantly correlated with facial width (exdochantion left to right, ZyL-ZyR), eye corner distances (endochantion left to right), midface height (nasion to subnasale), upper lip length (subnasale to stomion), and sex. The results suggest that digital 2D photogrammetry is as reliable as traditional anthropometry for assessing OVD, offering a noninvasive, reproducible, and storable alternative useful for prosthodontic rehabilitation.
