Abstract
The aim of this investigation was to establish precise indicators of the vertical dimension of occlusion (VDO) which
could be used as objective parameters in prosthodontic treatment providing exact control of the reconstructed vertical dimension
of occlusion, early detection of errors and correction of the vertical dimension of occlusion during complete denture
manufacturing. A total of 60 lateral cephalometric radiographs of subjects with natural dentition and class I skeletal
jaw relationship, of Serbian nationality from the region of Vojvodina, were included in the investigation. Thirty
subjects were males, and thirty females, their age range was 20 to 29 years. Cephalometric analysis was performed by using
»Dr. Ceph« computer software (FYI Technologies, GA, USA). By evaluation of the craniofacial complex in subjects
with natural dentition, horizontal dentofacial developmental growth was established in the examined sample and it was
based on the relationship between the posterior and anterior total facial height (S–Go:N–Me, b X=68.96%, aX=72.8%)
and statistically significant differences were found between the sexes in almost all linear dimensions and in the relation
between the posterior and the anterior total facial height. Highly significant differences (p<0.001) between the sexes were
found in regard to anterior total facial height (N–Me, aX=120.75mm, b X=112.72mm) and the anterior lower facial
height (ANS–Me, aX=67.87mm, b X=61.50mm) (p<0.05). The proportions of the upper and lower anterior facial
heights (N–ANS:ANS–Me, aX=79.36%, b X=80.63%) were within normal values in both sexes. Facial harmony existed
both in men and women. Cephalometric study of the subjects with complete natural dentition included in this study provided
important and specific parameters for optimal reconstruction of vertical dimension of occlusion in the treatment of
edentulous patients.
