Measures between anatomical landmarks to be correlated with the positions of the lingula.

Code	Definition	Description
ODAPD	Anteroposterior diameter of the mandibular ramus	Measured on a plane passing at Li and parallel to the OP.
VDCoMA	Vertical distance between the condyle and mandibular angle	Measured on the sagittal plane as the distance from the highest point of the mandibular condyle to the gonion.
D1M	Mesial–distal diameter of the first mandibular molar	Measured on the sagittal plane as the largest dimension of the crown in the mesial distal direction, parallel to the occlusal surface of the tooth.
D2M	Mesial–distal diameter of the second mandibular molar	Measured on the sagittal plane as the largest dimension of the crown in the mesial distal direction, parallel to the occlusal surface of the tooth.
D3M	Mesial–distal diameter of the third mandibular molar	Measured on the sagittal plane as the largest dimension of the crown in the mesial distal direction, parallel to the occlusal surface of the tooth.
ICD	Intercanine distance	Measured on the frontal plane and parallel to the OP.
DM1M	Distance between the right first mandibular molars and the left ones	Measured on the frontal plane, using the central fossae of the molars as landmarks.
DM2M	Distance between the right second mandibular molars and the left ones	Measured on the frontal plane, using the central fossae of the molars as landmarks.
DM3M	Distance between the right third mandibular molars and the left ones	Measured on the frontal plane, using the central fossae of the molars as landmarks.
DMI	Anteroposterior distance between the intermolar line of the first molars and the midline	Measured on the axial plane as the space between the midline passing through the lower incisors and the intermolar line 36–46.
LMAN	The length of the mandibular body	Measured on the sagittal plane between the most-posterior point of the mandible and the pogonion.
