Farklı Maloklüzyonlar ile Kafa Tabanı Açılanmaları Arasındaki İlişkinin Üç Boyutlu Değerlendirilmesi

Amaç: Bu çalışmanın amacı; farklı 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.

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

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.
