Abstract
Amaç: Bu çalışmanın amacı döküm Ni-Cr, fiber
post ve kompozit kor ve preslenmiş lithiumdisilicate post-kor sistemlerinin
kırılma dirençlerinin karşılaştırmalı değerlendirilmesidir.
Gereç ve Yöntem: Toplanan maksiler
anterior dişlere kanal tedavisi uygulandı. Kök uzunlukları 10 mm olacak şekilde
standardize edildikten sonra kök kanallarına post yuvaları hazırlandı. Toplamda
30 adet diş tesadüfi olarak 3 gruba ayrıldı(n=10). Post yuvalarının ölçüsü
patern rezin ile alındı ve laboratuara gönderildi. Laboratuar işlemleri sonrası
Ni-Cr ve Li-disilikat örnekler hazırlandı. Hazırlanan post korlar ve fiber
postlar duel-kür rezin siman ile post yuvalarına simante edildi. Test örnekleri oda ısısında 24 saat bekletildikten sonra 7 0 C- 50 0
C arasında termal döngüye maruz bırakıldı. Termal döngü sonrası test
örneklerine testometrik cihazında 1mm/dk hızla örnek kırılana kadar kuvvet
uygulandı. SPSS programı kullanılarak Tek yönlü ANOVA ve Dunnett T3 testi(α=0.05) ile verilerin istatistiği yapıldı.
Bulgular: Hazırlanan
döküm Ni-Cr test örneklerinin kırılma direnci 334.2 ±130.5
N, fiber-post kompozit kor örneklerin kırılma direnci 280.2 ±62.5
N, li-disilikat
örneklerin kırılma direnci ise 162.8 ±28.6 N bulunmuştur. Ni-Cr döküm
alaşımı kullanılan test örnekleri en yüksek kırılma direncini gösterirken,
li-disilikat grubundaki örnekler en düşük kırılma direncini göstermiştir. Ni-Cr
ve fiber post kompozit kor test örnekleri arasında istatistiki olarak anlamlı
fark bulunamamıştır
Sonuç:
Çalışmanın
sınırları dahilinde, estetik avantajları yüksek olmasına rağmen post kor
yapımında Li-disilikat kullanılması kırılma direncinin göreceli düşük olması
nedeniyle risk taşımaktadır.
