DOĞAL BAŞ POZİSYONU VE BELİRLEME YÖNTEMLERİ: LİTERATÜR DERLEMESİ

Günümüz ortodontik tedavi yaklaşımlarında sert dokularda elde edilecek değişimlerden öte, hastaların yumuşak dokularının tedavi süresindeki değişimleri önem arz etmektedir. Geçmişten bugüne teşhis ve tedavi planlamasında kullanılan ve kısmen geçerliliklerini kaybeden intrakraniyal referans noktaları, hastadan hastaya değişiklik gösteren anatomik varyasyonlar nedeniyle tedavi planını ve dolayısıyla tedavi sonucunu olumsuz etkileyebilir. Güncel yaklaşım ise estetik hedeflerin doğru belirlenebilmesi için yüz yapılarının gerçek zamanlı görünümüne öncelik vermektedir. Yumuşak dokularda meydana gelmesi istenen değişikliklerin ne yönde yapılacağının anlaşılması için kişinin baş ve yüz konumunun statik ve dinamik hareketler grubunda sergilediği pozisyonlar önemlidir. Doğal baş pozisyonunu (DBP) değerlendirmek için farklı metotlar kullanılmış ve bu anlamda ilk olarak statik yöntemler geliştirilmiştir. Statik yöntemler belirli bir süreçteki hareketler bütünü olan DBP’yi ölçmede yetersiz kalabilmektedir. Daha sonra kullanılmaya başlanılan dinamik DBP belirleme yöntemleri de zamanla geliştirilmiş ve statik-dinamik yöntemlerin kombinasyonları öne çıkmıştır. Bu derlemede DBP belirleme yöntemleri, geçmişten bu yana genel bir bakış açısı içinde anlatılacaktır.
