Abstract
Aim: This study aimed to evaluate the cranial base angulations in patients with different malocclusions by using cone-beam computed tomography (CBCT). Material-Methods: According to anteroposterior malocclusions, CBCT images of subjects (135 female, 98 male, average age: 13,05±1,79 ) were divided into three groups ; Class I, Class II and Class III. Cephalometric images were obtained from CBCT and patients were classified according to ANB angle. Sagittal, axial and coronal cranial base angulations were measured in three dimensional CBCT images. Cranial base angulation with different anteroposterior malocclusions were analyzed with the Kruskal-Wallis statistical test. Results: Sagittal cranial base measurements showed no significant differences between Class I, II and III groups (p>0.05). Also there were no significant differences between anteroposterior malocclusion groups according to coronal and axial cranial angle variables (p>0.05). Conclusion: According to the results, there were no effect of cranial base angulations in three planes (sagittal, coronal and axial) on different anteroposterior skeletal malocclusions. CBCT may be helpful for detecting and diagnosing morphological differences in anterior and posterior cranial base.
