title: Evaluation of craniometric methods for determination of vertical dimension of occlusion.
abstract: In clinical practice, fully precise method for exact determination of vertical relation of occlusion still does not exist. This study examines the relationship between different craniofacial distances and the distance subnasale-gnathion (Sn-Gn), which represents the lower third of the face in vertical relation determination. The highest coefficient of correlation was (r = 0.8678, p < 0.05) between the distance eye-ear (E-E = lateral border of the ocular orbit-medial opening of the meatus of the external auditory canal) and Sn-Gn. The prediction of the distance Sn-Gn could be determined through the formula: Sn-Gn = E-E/1.08 or through the regression analysis: Sn-Gn = 1.9197 + 0.6449 x E-E. None of the calculated coefficients of correlation was 1, but was < 1, so that the prediction of the distance Sn-Gn by craniometric distances is not absolutely reliable, although it is considerably helpful. Our results point at the variations of craniofacial distances in the Croatian population. Yet, craniometry could still be recommended in everyday clinical practice for prediction of vertical relation of occlusion, as it is a simple, economic and non-invasive method, however in combination with some other methods, which have proved to be helpful.
