Abstract
Introduction:
In young adults, the mandibular condyle plays an essential role in the stability of long-term orthodontic and orthognathic treatments. Its morphology varies significantly between individuals and is associated with age, sex, facial type, occlusal force, functional load, malocclusion type, and right and left sides.
Aim:
The aim of the study was to estimate the association between morphology of condyle, ramus height, and mandibular plane (MP) angle in young adult patients with various vertical skeletal growth patterns.
Materials and Methods:
The present study was conducted on 90 pretreatment panoramic radiographs of subjects aged between 17 and 21 year of age; the patients were divided into three groups as hypodivergent, normodiveregent, and hyperdivergent with 30 subjects in each group on the basis of Sella-Nasion-MP angle. Various parameters were measured to record the condyle morphology, ramus height, and mandibular angle for all the groups.
Results:
The intergroup comparisons showed that hypodivergent group has statistically significantly greater values compared to those in the hyperdivergent group. A statistically significant difference was detected between the normodivergent and hypodivergent groups only in the condylar area measurements
Conclusion:
The condylar height was greater in patient with Class I malocclusion. The condylar height width and other perimeters were greater in males than females.
