Fig. 6. Bone density measurement at the condyle. A, The axial slice with the largest mediolateral diameter of the mandibular condyle was selected. B, The condyle was re-oriented as the most medial and lateral points aligned in a horizontal line. C, Cortical bone densities at the medial and lateral points were measured (red dots), and cancellous bone density was measured in the middle 5 mm upon the line connecting the medial and lateral points.
