Facial Asymmetry in Individuals with Skeletal Class II Malocclusions.

Sharath S Kumar, and Ravi M Subrahmanya

Three dimensional evaluations of skeletal features is very important to differentiate skeletal and dental malocclusions and the factors contributing for malocclusion per se. Hence this study was designed with aim and objective of assessing the facial asymmetry in transverse plane in individuals having skeletal class II jaw discrepancy. 90 subjects (45 males and 45 females) aged 18-30 years were selected as per inclusion criteria. The facial asymmetry of skeletal class II individuals were compared using Grummon’s analysis in frontal cephalograms. The data obtained was statistically analyzed using Paired‘t’ test. Significant differences were observed between right side and left side values in relation to Ag-Me in males and Co-Ag-Me in females in group III individuals. Significant differences were observed between right side and left side values in relation to J-MSR in males in Group II individuals. Significant differences were observed between right side and left side values in relation to Me-MSR in males in Group II individuals. Facial asymmetry exists between right and left sides in class II individuals. Maxilla is more asymmetrical than mandible in patients with maxillary excess. Asymmetry showed male dominance in individuals with maxillary excess and mandibular deficiency.
