Our results demonstrated that anterior cranial base
inclination SN-FH was significantly larger in the high-angle class II division 1 group than in the average-angle and low-angle class II division 1 groups, which indicated that the anterior cranial base
of high-angle patients had an upward forward rotation.
Points, lines and angles used to assess the craniocervical angulation, sagittal position and length of jaws: N--nasion; S--sella; A--subspinale; B--supramentale; Me--menton; Gn--gnathion; A'--projection of the point A on the base plane of the maxilla; snp--spina nasalis posterior; cv2ip--most inferior and posterior point on the second cervical vertebra corpus; OPTodontoid process tangent through cv2ip point; NS--the anterior cranial base

Pakistani females also had a difference in the upper gonial angle and lower gonial angle (p less than 0.0001) and the anterior cranial base
, posterior cranial base, ramus height, anterior facial height, posterior facial height and mandibular corpus measurements.
A recent cephalometric study by Al-Jundi and co-workers  found that patients with HVDRR have deficiency in the anterior cranial base
length, maxillary length, and ramus height.
Study showed that the depth of the curve of spee in the mandibular arch was significantly related to overbite, overjet, and the sagittal position of the mandible with respect to the anterior cranial base
. The curve of Spee was not affected by gender.
