Sažetak

ABSTRACT. Aim: Many methods have been described to determine the occlusal vertical
dimension in edentulous patients, but none of them is completely reliable. The aim of this
study was to examine the possibility of reconstrucing the occlusal vertical dimension by using
a digital photography. Methods: Digital photographs (obtained from a 1.5 m distance with a
digital camera elevated to the height of the Frankfort plane) (frontal and profile) were
obtained from 55 dentate subjects clenching in maximum intercuspidation (ICP). Sn-Gn
(subnasale-gnation) and N-Sn (nasion-subnasale) distances were measured in the subjects and
in their photographs. The Sn-Gn distance of each subject was also calculated by using the
following formula: N-Sn (subject) x Sn-Gn (photograph) / N-Sn (photograph). Sn-Gn distance
was calculated from both the frontal and profile photographs. A statistical analysis was
performed (Kolmogorov-Smirnov test, descriptive statistical methods and Student t test
for dependent samples) (p<0.05). Results: There were no significant differences between
the Sn-Gn distance measured in a subject and the same distance calculated from a digital
photograph (from both, the profile and frontal photographs) (p>0.05). Conclusions: The
occlusal vertical dimension could be reconstructed from a digital photographs by using the
formula: N-Sn (measured on a subject) x Sn-Gn (measured on the photograph) / N-Sn
(measured on a photograph). Therefore, the general practitioner should obtain and keep
stored such photographs in a computer together with other dental records of an individual.
