Table 1 Description of three-dimensional (3D) cone-beam CT (CBCT) landmarks in the study

From: Three-dimensional soft tissue changes according to skeletal changes after mandibular setback surgery by using cone-beam computed tomography and a structured light scanner

LandmarksDefinition
Incision inferior (Ii)Midpoint of incisal edge of the mandibular central incisors
Lower canine (Lc dev/ctl)The highest point of mandibular canine cusp tip on deviated side (dev)/contralateral side (ctl)
Infradentale (Id)The most anterior point on the apex of the alveolar process between the mandibular central incisors
B point (B)The deepest point in the anterior outline of the mandible between infradentale and pogonion in the sagittal plane
Pogonion (Pog)The most anterior point in the mandibular chin area in the sagittal plane
Menton (Me)The most inferior point in the middle of the mandibular chin in the frontal plane
Mental foramen (Mf dev/ctl)The most inferior point on the lower edge of mental foramen on deviated side/contralateral side
