Fig. 3.

Axial slices and marked measuring points. Red lines are placed perpendicular to the panoramic image path and tangent to the landmark. Crosshairs represent measuring points placed by the three-dimensional measuring tool. Crosshairs are displayed in every axial slice between the actual measurement point locations. A, Marking of superior condylar surfaces bilaterally and measurement of condylion-gonion distance. B, Marking of the ramus cortex at gonion bilaterally. Inner values represent gonion-mental foramen measurements. Outer values depict condylion to gonion measurement distance. C, Marking of the inner cortical surface of the posterior aspect of the right mental foramen. Measurements are gonion to mental foramen measurement distances.
