Abstract

Objectives: To evaluate and compare the asymmetries in subjects with two malocclusions that is Class II subdivision, Class II div 1 and normal occlusion.
Materials and Methods : 90 subjects ranging from 15 to 30 years divided into 3 groups A, B, C. Group A – Class II subdivision, Group B – Class II division I, Group C – Normal Class I occlusion. Angular, linear paired, linear unpaired measurements were calculated based on the Van De Coppell analysis using PA views.
Results: Asymmetry was found in all the three groups where Group A patients showed greater degree of asymmetry near maxillary buttress and piriform aperture areas compared to the three groups. Group C patients showed greater degree of asymmetry in the occlusal plane angle.
Conclusion: All the three malocclusions that is Class II div 1 Subdivision, Class II div 1 and Class I malocclusions showed equal amounts of asymmetry. Class II subdivision patients showed greater asymmetry near maxillary buttress area and piriform aperture. Class I malocclusion showed deviation in occlusal plane angle. Along with the lower third involving mandible, maxillary area also can equally show asymmetry in both skeletal and dental parameters.
 

Keywords: Asymmetry, Piriform aperture, Maxillary buttress.
