Reference points and measurement of sagittal view in CBCT. C1 highest point of glenoid fossa, C2 highest point of condylar head, D1 lowest point of articular eminence, D2 lowest point of temporal squamotympanic fissure, L3 line passing D1 and D2, D3 point meeting the perpendicular line from C1 on L3, D4 point meeting the perpendicular line from C2 to L3, M distance between D1 and D2, m distance between D1 and D3, N distance between C1 and D3, n distance between C2 and D4, S–N n/N (assessed by ratio of vertical location of mandibular condyle at glenoid fossa), S–M, m/M (assessed by ratio of horizontal location of mandibular condyle at glenoid fossa)
