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.

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
