RESİPROKAL HAREKET İLE KULLANILAN ISIL İŞLEM GÖRMÜŞ TEK EĞE NİKEL TİTANYUM SİSTEMLERİN VÜCUT SICAKLIĞINDA DÖNGÜSEL YORGUNLUK DİRENÇLERİNİN KARŞILAŞTIRILMASI

Amaç: Bu çalışmanın amacı WaveOne Gold, Reciproc Blue ve North Profa RC Blue nikel titanyum (NiTi) tek eğe döner sistemlerin vücut sıcaklığında döngüsel yorgunluğa bağlı kırılma dirençlerinin karşılaştırılmasıdır. Gereç ve Yöntemler: Bu çalışmada WaveOne Gold, Reciproc Blue ve North Profa RC Blue döner eğe sistemlerinin her birinden on ikişer adet kullanıldı. Tüm eğeler statik model döngüsel yorgunluk deney düzeneğinde, 60°’lik kurvatür açısına, 5 mm kurvatür yarıçapına ve 1,4 mm kanal iç çapına sahip seramik yapay kanallarda ve 37°C’de kırılıncaya kadar kullanıldı. Eğelerin kırılma zamanı dijital kronometre ile kaydedildi ve kırılıncaya kadarki tur sayıları hesaplandı. Normal dağılım göstermediği saptanan veriler Kruskal-Wallis H testi ile analiz edildi. Tahmini sağlam kalma oranının belirlenmesi için Weibull analizi yapıldı. Bulgular: North Profa RC Blue grubu ile Reciproc Blue grubu arasında ve Reciproc Blue grubu ile WaveOne Gold grubu arasında döngüsel yorgunluk direnci bakımından istatistiksel olarak anlamlı bir fark görülmedi (p> 0.05). North Profa RC Blue eğelerin döngüsel yorgunluk direnci WaveOne Gold eğelerden istatistiksel olarak anlamlı derecede yüksek bulundu (p
