Abstract
Statement of problem
Determining the vertical dimension of occlusion for an edentulous patient depends
on clinical judgment and the skill and experience of the dentist. Though many methods
have been advocated, a universally accepted method of determining the vertical dimension
of occlusion in edentulous patients is lacking.
Purpose
This clinical study aimed to find a correlation between the intercondylar distance
and occlusal vertical dimension in dentate individuals.
Material and methods
This study was conducted on 258 dentate individuals aged 18 to 30 years. The Denar
posterior reference point was used to determine the center of the condyle. The posterior
reference point was marked on either side of the face with this scale, and the intercondylar
width between these 2 posterior reference points was measured with custom digital
vernier calipers. A modified Willis gauge was used to measure the occlusal vertical
dimension from the base of the nose to the lower border of the chin when the teeth
were in maximum intercuspation. The relationship between the ICD and OVD was analyzed
with the Pearson correlation test. Simple regression analysis was used to formulate
a regression equation.
Results
The mean intercondylar distance was 133.5 mm, and the mean occlusal vertical dimension
was 55.4 mm. A statistically significant correlation (R=0.619) was found between the
intercondylar distance and occlusal vertical dimension in the study population (P<.001).
Conclusions
A significant correlation was found between the intercondylar distance and occlusal
vertical dimension of the participants. Occlusal vertical dimension may be predicted
from the intercondylar distance by using a regression model.
