Amaç: Bu in-vitro çalışmada, monokromatik yapıdaki tek katmanlı ve polikromatik yapıdaki çok katmanlı monolitik zirkonya seramiklerin farklı yüzey işlemleri ve yaşlandırma işlemi sonrası yüzey pürüzlülüğünün değerlendirilmesi amaçlandı.
Gereç ve Yöntem: Tek katmanlı (ZirCAD MT) ve iki farklı çok katmanlı zirkonya seramik (ZirCAD MT Multi ve ZirCAD Prime) bloklardan 12 x 12 x 1 mm ebatlarında A2 renginde toplam 60 örnek üretildi. Örnekler mekanik polisaj ve glaze işlemlerine göre iki alt gruba ayrıldı (n=10). Sonrasında tüm örnekler, 10000 devir termal siklus ile yaşlandırma işlemine tabi tutuldu. Her grup için yaşlandırma işlemi öncesi ve sonrası ortalama yüzey pürüzlülüğü değerleri (Ra) profilometre cihazı ile ölçüldü. Elde edilen sonuçların değerlendirilmesi için tekrarlı ölçümlü üç yönlü ANOVA testi kullanıldı (α=0.05).
Bulgular: Termal siklus uygulamasıyla ortalama Ra değerleri arasındaki değişim istatistiksel olarak anlamlı bulundu (P<0.05). Glaze ve polisaj uygulanan gruplarda, termal siklus sonrasında yüzey pürüzlülüğünün arttığı belirlendi. Glaze gruplarında Ra değerlerinin ortalaması 0.031 µm olarak bulunurken, polisaj gruplarında Ra değerlerinin ortalaması 0.047 µm olarak bulundu (P<0.05). ZirCAD MT Multi materyalinde ortalama Ra değerleri diğer monolitik seramik gruplarına göre anlamlı olarak daha düşük bulundu (P<0.05). ZirCAD MT ve ZirCAD Prime seramik gruplarında ortalama Ra değerleri arasında anlamlı fark bulunmadı (P=0.476).
Sonuç: Bu in-vitro çalışmanın sınırlamaları dahilinde, test edilen monolitik zirkonya seramiklerde termal siklus ile yaşlandırma sonrası yüzey pürüzlülüğü değerleri artmaktadır. Glaze işlemi, mekanik polisaj işlemine göre daha az yüzey pürüzlülüğüne neden olmaktadır. Tüm monolitik zirkonya seramik grupları arasında ZirCAD MT Multi materyali daha düşük yüzey pürüzlülüğü değerlerine sahiptir.

Öz
Aim: The aim of this in vitro study is to evaluate the surface roughness of monochromatic monolayer and polychromatic multilayer monolithic zirconia ceramics after different surface treatments and aging process.
Materials and Method: A total of 60 specimens, in A2 color and 12x12x1 dimensions, were prepared from monolayer (ZirCAD MT) and two different multilayered zirconia ceramic blocks
(ZirCAD MT Multi and ZirCAD Prime). The specimens were divided into two subgroups according to mechanical polishing and glazing (n=10). Then, all specimens were subjected to 10000 cycles of thermocycling. Average surface roughness values (Ra) for each specimen was measured with a profilometer before and after aging. Repeated measures of three-way ANOVA test was used for the statistical evaluation (α=0.05).
Results: The difference between the mean Ra values with the thermocycling was found to be statistically significant (P<0.05). Surface roughness increased after thermocycling in glazed and polished groups. The average Ra values of the glazed groups was found to be 0.031 μm, while the average Ra values of the polished groups was 0.047 μm (P<0.05). The mean Ra values of ZirCAD MT Multi material were found to be significantly lower than the other monolithic ceramic groups (P<0.05). There was no significant difference between mean Ra values in ZirCAD MT and ZirCAD Prime ceramic groups (P=0.476).
Conclusion: Within the limitations of this in vitro study, thermocycling increases the surface roughness values of the tested monolithic zirconia ceramics. Glazing results in lower surface roughness values than mechanical polishing. Among all monolithic zirconia ceramic groups, ZirCAD MT Multi material has lower surface roughness values.
