Abstract

Introduction: To assess condylar position using Gelb’s grid in subjects with different malocclusion.
Materials and Methods: Pre- treatment lateral cephalogram of 45 subjects (aged above 18yrs) were taken and equally divided in three groups, Group I(skeletal Class I malocclusion), Group II-(skeletal Class II malocclusion) and Group III (Class III malocclusion) based on three Cephalometric parameters (ANB, Yen angle and Wits appraisal). Condylar position in relation to glenoid fossa was assessed with Gelb’s grid.
Results: For Group I condyle was positioned normally (4,7) in 86.66% of subjects and was positioned posteriorly (5,8)13.33% of subjects. For Group II condyle was displaced posteriorly (5,8) in 86.66% of subjects and in normal position (4,7) for remaining subjects. For Group III subjects condyle was again found in posteriorly displaced 66.66% of subjects and normally positioned in rest of subjects.
Conclusion: It can be suggested that the condylar position showed variability in three malocclusion groups. Class I malocclusion group with no skeletal discrepancy was associated with more symmetric normal condylar position than malocclusion groups with skeletal discrepancy (Class II and Class III).
