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, female X=68.96%, male X=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, male X=120.75 mm, female X=112.72 mm) and the anterior lower facial height (ANS-Me, male X=67.87 mm, female X=61.50 mm) (p<0.05). The proportions of the upper and lower anterior facial heights (N-ANS:ANS-Me, male X=79.36%, female 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.
本研究的目的是建立精确的咬合垂直距离（VDO）指标，这些指标可作为口腔修复治疗中的客观参数，以精确控制重建的咬合垂直距离，在全口义齿制作过程中早期发现错误并纠正咬合垂直距离。本研究纳入了来自伏伊伏丁那地区的60例具有天然牙列且骨骼型为I类颌关系的塞尔维亚籍受试者的头颅侧位片。其中30例为男性，30例为女性，年龄范围为20至29岁。使用“Dr. Ceph”计算机软件（美国佐治亚州FYI Technologies公司）进行头影测量分析。通过对具有天然牙列受试者的颅面复合体进行评估，在所检查的样本中确定了水平牙颌面发育生长情况，其依据是面部后总高与前总高之间的关系（S-Go:N-Me，女性X=68.96%，男性X=72.8%），并且在几乎所有线性维度以及面部后总高与前总高的关系方面，发现两性之间存在统计学显著差异。在面部前总高（N-Me，男性X=120.75 mm，女性X=112.72 mm）和面部下前高（ANS-Me，男性X=67.87 mm，女性X=61.50 mm）方面，两性之间存在高度显著差异（p<0.001）（p<0.05）。两性的上下面部前高比例（N-ANS:ANS-Me，男性X=79.36%，女性X=80.63%）均在正常范围内。男性和女性均存在面部协调性。本研究中对具有完整天然牙列的受试者进行的头影测量研究为无牙患者治疗中咬合垂直距离的最佳重建提供了重要且具体的参数。
