Digital Photo Analysis as a Predictor of Physiological Vertical Dimension

Abstract

Determination of the vertical dimension is based on patient's resting jaw position, which is the physiological vertical dimension. Objective: To examine the accuracy of physiological vertical dimension using digital photography. Methods: The research was done on 64 students who meet the criterias. The measurements of eyes-lips angles and lower nose-chin distance was performed. Then photo shoot of subject faces was taken from 56cm distance between the camera lens and the tip of the subjects’ nose with tripoded camera. Results: Distance of eyes-lips angles, and lower the nose-chin of the face and the photo has no meaningful differences. Conclusions: Analysis of digital photos can be applied to predict physiological vertical dimension.DOI: 10.14693/jdi.v18i2.62
