Background: Mandibular condyle varies in terms of shape and size due to several attributable factors such as developmental variations, genetic factors or remodelling. Remodelling can be caused by functional forces from developmental variations/abnormalities, malocclusion or trauma. A thorough understanding of the normal variant is significant to differentiate an abnormal condition.
Aim: The present study aims to evaluate the variation in the shape of the condyle in various vertical discrepancies of the jaw.
Materials and Method: 50 Lateral cephalograms which satisfied the inclusion criteria were obtained from the department database and cephalometric analysis was performed to categorise them into Open bite and Deep bite cases. Their orthopantomogram were obtained and the shape of condylar heads were categorised using the classification by Chaudhry et al. Descriptive analysis was done .
Results: This study showed that the shape of the condylar head in Open bite cases consisted of 76% oval shape,16% diamond shape and 8% bird beak shape. Shape of the condylar head in Deep bite cases consisted of 64% oval shape, 20% diamond shape, 12% bird beak shape and 4% crooked finger shape.
Conclusion: This study showed that the oval shape is the most common shape of the condylar head in vertical discrepancies accounting for 76% in Open bite and 64% in Deep bite cases.
