ABSTRACT

Submentovertex cephalometric analysis was used to assess mandibular symmetry between 28 patients with Class II subdivision malocclusion and 20 controls with Class I malocclusions. Using the condylar line and the condylar axis, the relative differences were measured between mandibular landmarks in both anteroposterior and transverse dimensions. Anteroposterior and transverse differences between left and right mandibular positions and transverse position of the dental midline showed a statistically significant difference between the groups. Position of the coronoid process also showed a difference between the two groups. The present study has concluded that the entire mandibular dentition is rotated in Class II subdivision malocclusions.
