S = Sella; N = Nasion; Ans = Anterior nasal spine; Pns = Posterior nasal spine; A = Point A (most concave point of anterior maxilla); B = Point B (most concave point of mandibular symphysis); Ui tip = Upper incisor tip; Li =lower incisor tip; Ui root = Upper incisor root; Li root = Inferior incisor root; Gn = Gnathion (midpoint between Pg and Me); Me = Menton (most inferior point of mandibular symphysis); Go = Gonion (the point located at the gonial angle of the mandible); Ar = (junction between inferior surface of the cranial base and the posterior border of the ascending rami of the mandible).
