Temporomandibular Joint Morphology in Normal Occlusion- A Cone Beam Computed Tomography Study
Rakhi Bharat, Rinku Saini Jagnade

Background: The ideal position of the condyle in the glenoid fossa of the temporomandibular joint (TMJ) is one of the most hot topics found in dentistry with a lot of fundamental questions. The present study aimed to investigate the morphology of the TMJ in Normal  occlusion  (skeletal class-I)  by cone beam computed tomography. Materials and Method: In this study patients, age group range from 15 to 22 years  were taken  who needed CBCT scan for their treatment. Bilateral TMJs were evaluated on the volumetric images, and the following three-dimensional measurements were obtained: 1) mandibular fossa position, inclination, and parameters; 2) mandibular condyle position, inclination, and parameters; 3) TMJ space measurements; and 4) centralization of the condyles in their respective mandibular fossae. The multiplanar images were evaluated for the surface-area measurements. Results & Conclusion: There were no significant mean differences found for all parameters in right side and left side of subjects, when skeletal class I. In the evaluation of centralization of the condyle on the right side in subjects with skeletal class 1 occlusion the mean values was statistically significant where as on the left side the mean values were not significant.The right side anteroposterior diameter of condylar process in class I subjects found strongly correlated and highly significant with left side . The anteroposterior difference between the geometric center of the right & left condylar processes  in skeletal class-I found with geometric center  situated anterior to the zero point reflected positive. Anteroposterior differences between the geometric center of the right and left condylar processes  class I  subjects, The concentric was greater and positive in normal occlusion.
