Objective: The aim of this study was to compare the effect of anodization and air-particle abrasion surface treatments on shear bond strength between Ni-Cr and ceramics.
Material and Methods: 30 cylindrical Ni-Cr specimens (7x10 mm) were divided into three groups according to the surface treatments [control group (no-treatment), air-particle abrasion group (110 µm Al2O3at 75 psi from 20 cm for 30 seconds), and anodization group]. One sample from each group was evaluated by using SEM. Ceramics with a dimension (5x3 mm) built-up on specimens and shear bond strength tests were performed by using universal testing machine with a 1 mm/min crosshead speed. Stereomicroscope was used to evaluate the failure mode of specimens. One-way ANOVA with post-hoc Tukey’s test was used to analyze the differences in shear bond strength values.
Results: The shear bond strength of air-particle abrasion (21,35∓4,64) was higher than anodization group (20,92∓4,85) however, no statistically significant difference was detected. Both groups showed higher bond strength than control group (8,02∓1,47).
Conclusion: Anodization process can be used in order to increase the metal-ceramic bond strength. However, according to the failure mode, air-particle abrasion forms stronger bond strength than anodization.Amaç:Bu çalışmanın amacı, anodizasyon ve kumlama yüzey işlemlerinin Ni-Cr ve seramik arasındaki makaslama bağlantı dayanımı üzerine etkilerini karşılaştırmaktır.
Gereç ve Yöntem: 30 adet silindir şeklinde Ni-Cr örnek (7x10 mm) uygulanan yüzey işlemlerine göre üç gruba ayrıldı [kontrol grubu (hiç işlem görmedi), kumlama grubu (110 µm Al2O3, 75 psi basınçla, 20 cm uzaklıktan, 30 saniye süresince) ve anodizasyon grubu]. Her gruptan birer örnek alınarak SEM analizleri gerçekleştirildi. Hazırlanan örneklerin üzerine 5x3 mm boyutlarında seramikler pişirildi ve makaslama bağlantı dayanım testleri universal test cihazında kafa hızı 1mm/dk olacak şekilde gerçekleştirildi. Örneklerin kopma şekillerinin tespitinde stereomikroskop kullanıldı. Makaslama bağlantı dayanım değerlerinin analizinde One-way ANOVA ve post-hoc Tukey’s testleri kullanıldı.
Bulgular:Kumlama grubunun makaslama bağlantı dayanımı (21,35∓4,64) anodizasyon grubuna (20,92∓4,85) göre yüksek olarak bulunmasına ragmen her iki grup arasındaki farklılık istatistiksel olarak önemli bulunmamıştır. Her iki grupta kontrol grubuna göre (8,02∓1,47) yüksek bağlantı dayanımına sahip olduğu tespit edilmiştir.
Sonuç:Anodizasyon uygulaması metal-seramik bağlantısının artırılması için kullanılabilecek bir yöntem olarak kullanılabilir, lakin kırılma şekilleri dikkate alındığında kumlama işleminin anodizasyon uylamasına göre daha güçlü bir bağ oluşturmaktadır.
