Abstract

Amaç: Rezonans frekans analizinin (RFA) amacı implantların kemik içindeki stabilitesini ölçmektir.
Bu stabiliteyi etkileyebilecek faktörlerden birinin kemik yoğunluğu olduğu beklenebileceği için, bu
çalışmada klinik olarak tedavi sırasında hastalardaki kemik yoğunluğu ile ölçülen RFA değerlerinin
arasındaki ilişkinin incelenmesi amaçlanmıştır.
Gereç ve Yöntem: 27 hastada 54 implant alt çene interforaminal bölgede 33 ve 43 nolu bölgelere
aynı hekim tarafından her birinin çap ve boyu 4,5/13 mm olacak şekilde yerleştirilmiştir. Operasyon
sırasında, cerrahi işlemleri gerçekleştiren hekim tarafından yuva açtığı sırada hissettiği direnci değerlendirmek
suretiyle kemik sınıflaması yapılmış ve kaydedilmiştir. Ayrıca Osstell™ mentor cihazı ile
Smartpeg™'lere 90° açı yapacak şekilde uygulanarak 2 farklı yönde iki ölçüm gerçekleştirilmiş ve
bunların aritmetik ortalaması alınarak tek bir ISQ skoru olarak kaydedilmiştir.
Bulgular: Çalışmaya katılan hastaların alt çene kemik tipleri 4 bireyde Tip 1, 17 bireyde Tip 2, 6
bireyde de Tip 3 olarak tespit edilmiştir. Bireylerin hiçbirinde Tip 4 kemiğe rastlanmamıştır. Kemik
tipine göre hastalardan alınan ISQ değerlerinde, gerek 33 nolu implantlarda gerekse de 43 nolu implantlarda
istatistiksel olarak anlamlı farklılık saptanmamıştır (p > 0.05).
Sonuç: Bu çalışmanın sonuçlarına dayanarak, sadece RFA değerlerine dayanarak kemik tipi sınıflaması
yapılmasının güvenilir bir yöntem olmadığı iddia edilebilir.
