Aim : The aim of this study to examine the differences between cranial base measurements and different skeletal malocclusion patterns in patients with Turkish cephalometric norms, data that will be useful in diagnosis and orthodontic and jaw surgery treatment planning. Materials and Methods : Cranial base measurements were made on lateral cephalometric radiographs of 90 healthy orthodontic patients with different skeletal malocclusions (Class I: 30 subjects, Class II: 30 subjects, Class III: 30 subjects) with a normal vertical growth pattern. Cranial base flexure measurements, anterior and posterior cranial base inclinations, and linear measurements for the assessment of cranial base dimensions were analyzed. For statistical evaluation, one-way analysis of variance test was performed. Least significant differences test was used to determine the individual differences. Results : Both anterior (SN) and posterior (SBa) cranial base lengths, N-SBa cranial base flexure angle and posterior cranial base inclination angle (SBa-FH) did not show statistically significant differences between the three groups studied. Anterior cranial base inclination (SN-FH) was increased significantly in the Class II group compared to Class I and Class III groups. N-S-Ar cranial base flexure angle was also increased significantly in the Class II group compared to Class III. Conclusions : Cranial base morphology differences among skeletal malocclusions were observed for the N-S-Ar and SN-FH angles in Class II group.
