Aim: To evaluate the effect of cranial base parameters on mandibular parameters in class II division 1 malocclusion in three dimensions. Materials and Methods: The sample consists of 103 students age range between (18-24) years, 103 students (50 males and 53 females) having class II division 1malocclusion. Lateral and posteroanterior radiographs were taken for each subject. Cranial base measurement included (five angular and seven linear measurements). Mandibular measurement included (six

Results: Cranial base flexures play a role in determination of lower jaw position which represented by significant effect of cranial base angles (N-S-Ba, N-S-Ar and S-Ba-N) on the angles (SNB, SN-Pog and SN-Id).
