Table 2 Cephalometric points for sagittal and vertical skeletal jaw arrangement (Chalala et al. 2019; Rana et al. 2012)
From: Orthodontists in forensic facial approximation (FFA): current inter-disciplinary perspective
Cephalometric point/angle | Explanation |
|---|---|
Point A (subspinale) | Deepest midline point in concavity from anterior nasal spine (ANS) to prosthion |
Point B (supramentale) | Deepest midline point between infradental and pogonion. |
Point Na (nasion) | Intersection of nasofrontal suture with internasal suture in mid-sagittal plane |
ANB | Angle between the line subspinale to nasion and line joining nasion to supramentale Inference: > 4° = skeletal class II relation 2°±2°= skeletal class I relation ≤ 0°= skeletal class III relation |
MPA (mandibular plane angle) | Angle formed at intersection of mandibular plane (GO-Me) and sella-nasion (SN) |
