Characteristics of Craniofacial Complex for Class II Division 1 Malocclusion in Saudi subjects with permanent dentition
European-American norms are still used in the orthodontic treatment of Saudi patients, despite the different ethnic backgrounds of Saudis. The aims of this study were to evaluate the Cephalometric features of Class II division 1 in Saudi adult patients and to compare these values with those features of normal occlusion by referring to the effect of the gender on these values. Ninety-four (94) Saudi patients were evaluated Cephalometrically and distributed into two groups where the first group comprised of (45) subjects with normal occlusion. The second group comprised of (49) subjects with Class II division 1. Wide variations were observed for almost all measurements of Class II division 1.However, a posteriorly positioned mandible and shortness in its dimensions were noticed. Patients were found to have vertical growth pattern and posterior rotation of mandible, buccal inclination of upper and lower incisors and an increased cranial base angle were all main characteristics of Class II divisions 1 patients. The comparison between the two genders revealed that the males have bigger facial dimensions than females, but the angular measurements were similar referring to the resemblance in the craniofacial morphology.
