Three Dimensional Evaluation of Relationship Between Cranial Base Angulations and Different Malocclusions

Aim: This study aimed to evaluate the cranial base angulationsin patients with different malocclusions by using cone-beam computedtomography (CBCT). Material-Methods: According to anteroposteriormalocclusions, CBCT images of subjects (135 female, 98male, average age: 13,05±1,79) were divided into three groups; ClassI, Class II and Class III. Cephalometric images were obtained fromCBCT and patients were classified according to ANB angle. Sagittal,axial and coronal cranial base angulations were measured in threedimensional CBCT images. Cranial base angulation with different anteroposterior malocclusions were analyzedwith the Kruskal-Wallis statistical test.Results:Sagittal cranial base measurements showed nosignificant differences between Class I, II andIII groups (p>0.05). Also there were no significantdifferences between anteroposterior malocclusiongroups according to coronal andaxial cranial angle variables(p>0.05).Conclusion: According to the results,there were no effect of cranial base angulationsin three planes (sagittal, coronal and axial) ondifferent anteroposterior skeletal malocclusions.CBCT may be helpful for detecting anddiagnosing morphological differences in anteriorand posterior cranial base.

Farklı Maloklüzyonlar ile Kafa Tabanı Açılanmaları Arasındaki İlişkinin Üç Boyutlu Değerlendirilmesi

Amaç: Bu çalışmanın amacı; far klı maloklüzyonu olan hastalarda kafa tabanı açılanmalarının konik ışınlı bilgisayarlı tomografi (KIBT) ile değerlendirilmesidir.Gereç-Yöntem: Anteroposterior maloklüzyonlara göre, hastalardan elde edilen KIBT görüntüleri (135 kadın, 98 erkek, ortalama yaş: 13,05 ± 1,79) Sınıf I, Sınıf II ve Sınıf III olarak üç gruba ayrıldı. KIBT'dan sefalometrik görüntüler elde edildi ve hastalar ANB açısına göre sınıflandırıldı. Üç boyutlu KIBT görüntülerinde sagital, aksiyel ve koronal kafa tabanı açılanmaları ölçüldü. Farklı anteroposterior maloklüzyonlarla kafa tabanı açılanmaları Kruskal-Wallis istatistiksel testi ile analiz edildi.Bulgular: Sagital kafa kaidesi ölçümleri Sınıf I, II ve III grupları arasında anlamlı bir fark göstermedi (p> 0.05). Koronal ve aksiyel kraniyal açı değişkenlerine göre anteroposterior maloklüzyon grupları arasında da anlamlı farklılık yoktu (p> 0.05).Sonuç: Elde edilen sonuçlara göre, kafa tabanı açılanmalarının üç düzlemde de (sagital, koronal ve aksiyal) farklı anteroposterior iskelet malokluzyonları üzerine herhangi bir etkisi bulunmamaktadır. KIBT, anterior ve posterior kafa tabanındaki morfolojik farklılıkların tespiti ve teşhisi için yararlı olabilir
