The axial condylar angle - the angle between the long axis of the condylar process and the midsagittal plane in the axial view; the distance between the geometric centers of the condylar processes and the midsagittal plane - measured with a line that passed through the geometric centers of the condylar processes and perpendicular to the midsagittal plane; the condyle - fossa relationship - the rate of joint spaces in axial, coronal and sagital plan, and in comparison the position of left and right condylar in the axial and coronal planes.
