Definitions of Anatomic Contours

Landmark definition	Definition
Superior contour (UCo)	Most superior extent of the mandibular condyle from the anterior, mesial, lateral, and superior planes of view.
Lateral contours (LCos)	Most lateral extent of the mandibular condyle viewed from the anterior, posterior, lateral, and superior planes of view
Inferior contour (ICo)	Most inferior extent of the mandibular condyle from the anterior, mesial, lateral, and superior planes of view. The exact cut where the surface of coronal section increase (because of the beginning of sigmoid area) instead of decrease. This cut allowed the segmentation of the condylar head, without the sigmoid area.
