Sınıf II Maloklüzyonlarda Sagittal ve Vertikal Kraniyofasiyal Morfoloji
Özet
Sınıf II maloklüzyonlar, tek bir kraniyofasiyal morfolojiyle açıklanamayan, iskeletsel ve dentoalveoler bileşenlerin farklı kombinasyonlarıyla ortaya çıkabilen heterojen anomalilerdir. Bu bölümde Sınıf II maloklüzyonların sagittal ve vertikal kraniyofasiyal özellikleri ile bu iki düzlem arasındaki etkileşim güncel literatür doğrultusunda ele alınmaktadır. Kraniyal kaide, maksilla ve mandibulanın konumu; mandibuler büyüme ve rotasyon modeli; yüz yükseklikleri, ramus, korpus ve simfizis morfolojisi ile dentoalveoler kompanzasyonların Sınıf II morfolojisine katkıları değerlendirilmektedir. Ayrıca hipodiverjan, normodiverjan ve hiperdiverjan büyüme paternlerinin sagittal çene ilişkisi ve dental kapanış üzerindeki etkileri incelenmekte; Sınıf II Bölüm 1 ve Sınıf II Bölüm 2 maloklüzyonlar arasındaki dental ve iskeletsel farklılıklar sagittal–vertikal etkileşim çerçevesinde tartışılmaktadır. Mevcut bulgular, benzer sagittal ilişkilerin farklı morfolojik mekanizmalarla ortaya çıkabileceğini ve vertikal büyüme paterninin bu çeşitliliğin önemli bir belirleyicisi olduğunu göstermektedir. Bu nedenle Sınıf II maloklüzyonların tanı ve tedavi planlamasında sagittal çene ilişkisi, vertikal büyüme paterni, dentoalveoler kompanzasyonlar ve anatomik sınırların birlikte değerlendirilmesi, bireye özgü klinik yaklaşım açısından önem taşımaktadır.
