Measures considered in the present study to determine the exact location of the lingula.

Code	Definition	Description
VDLiOP	Distance of the Li from the OP	Measured on the coronal plane and perpendicular to the OP
ODLiAB	Distance of the Li from the anterior border of the mandible parallel to the OP	Measured on the axial plane passing through the ML and parallel to the OP
ODLiPB	Distance of the Li from the posterior border of the ramus	Measured on the axial plane passing through the ML and parallel to the OP
VDLiSN	Distance of the Li from the lower point of the sigmoid notch	Measured on the sagittal plane and perpendicular to the OP
VDLiMB	Distance of the Li from the mandibular base	Measured on the frontal plane passing through the Li and perpendicular to the OP
ODLi2M	Distance of the Li from the distal surface of the mandibular second molar tooth	Measured in the plane parallel to the OP passing through the Li, from the orthogonal projection of the most distal point of the crown to the Li

Li: lingula; OP: occlusal plane.
