Aims: This study aims to determine the links between the temporomandibular joint's parts using an MRI scanner. Methods and Material: 18 patients (16–45 years old; 10 females, 8 men) were chosen who had no symptoms in either temporomandibular joint. Each patient had a two-axis sequential T1 interfacial non-magnetic single-weighted image taken while having their mouths closed and in the appropriate posture for maximum opening. A 1.5 Tesla MR scanner was used to perform an MRI scan. Condyle-head, glenoid-fossa shape, articular-stoma, and post-glenoid process were traced for each MRI in positions both closed and open. The data were statistically examined using the Student's t-test to compare measures of the right and left glenoid fossa depth, condyle position, and angle in both gender. Results: Results revealed no remarkable changes in deepness (mm) of the glenoid fossa (8±0.27), the β-angle (mm) at which a male's and a female's right and left sides articular surfaces are inclined (50±1.4), and condyle location (mm) in open mouth (6.9±0.2). In contrast to females, however, males had a larger value for the glenoid fossa depth (8 mm versus 7.9 mm), and they found a correlation between articular thickness tendency and the position of the condyle in the open mouth and the depth of glenoid-fossa. Conclusions: The deepness of the glenoid-fossa, the position of the condylar head in the open mouth, or any other characteristic did not differ noticeably between the right and left sides of males or females, or the regression of the articular thickness (angle). With MRI equipment, the same analysis technique utilized in traditional radiography can be applied with success.
