AB-MF, distance from midpoint of anterior margin of mandibular foramen to the nearest point on anterior border of ramus; PB-MF, distance from midpoint of posterior margin of mandibular foramen to the nearest point on posterior border of ramus; AB-PB, distance from anterior to posterior border of ramus; foramen width, calculated by subtracting, from AB-PB, the sum of the distances AB-MF and PB-MF; MF-MN, distance from mandibular notch to inferior limit of mandibular foramen; MF-MB, distance from mandibular base to inferior limit of mandibular foramen; III Molar-MF, distance from III Molar to mandibular foramen; RT-MF, distance from apex of retromolar Trigone to mandibular foramen.
