Cephalometric evaluation to re-establish occlusal vertical dimension utilizing a proposed linear skeletal distance: A cross-sectional study

Abstract

Statement of problem:  Establishing a correct occlusal vertical dimension is considered one of the most important aspects of facial esthetics for edentulous patients in the absence of pre-extraction records.

Purpose: The aim of the study was to evaluate the use of proposed linear skeletal distance to predict the appropriate occlusal vertical dimension.

Material and methods: A total of 180 lateral cephalometric radiographs with natural dentition in class I skeletal relationships were included in the study. The sample comprised of 100 females and 80 males ranging in the age from 18 to 30 years. In the study the distance from Nasion (Na) to Sella (Se) and the distance from anterior nasal spine (ANS) to menton (Me) were measured on the cephalometric radiographs. The data were compared statistically using the Pearson correlation coefficient and paired t’ test.

Result: The findings of the study revealed a positive correlation (p<0.134) between the measured distance in men and women, with statistically not significant p’ value among the group (ANS- Me) and (Na-Se).

Conclusion: The distance from Na to Se can be used as an additional aid in estimating the occlusal vertical dimension in both men and women for the study population.
