Abstract

Amaç: Bu pilot çalışmanın amacı farklı yüzey işlemleri uygulanmış zirkonya yüzeyi ile rezin siman arasındaki sızıntının değerlendirilmesidir.Gereç ve Yöntemler: Farklı yüzey hazırlıklarına tabi tutulmak üzere 6 gruba ayrılan örneklerden 1. grup yüzey işlemi uygulanmadan kontrol grubu (grup 1) olarak ayrıldı. Grup 2’deki örnekler 110 μm olan alüminyum oksit (Al2O3) kumu ile pürüzlendirildi. Grup 3’teki örnekler 110 μm olan Al2O3 kumu ile pürüzlendirildikten sonra silika kaplandı ve silan (espe-sil) uygulandı. Grup 4’teki seramikler, neodymium: yttriumaluminum-garnet lazer cihazı [fidelis plus 3 fotona (Ljubljana, Slovenia)] kullanılarak pürüzlendirildiler. Cihazın paneli 20 hz, 100 mj, 2 w, 100 μs olacak şekilde ayarlandı. 5. gruptaki seramikler de lazerle pürüzlendirildi ve cihaz; 20 hz, 150 mj, 3 w, 100 μs olarak ayarlandı. Grup 6’daki örneklere ise çift kat zirconia primer (z-prime plus bisco, İL, ABD) uygulandı. Hava ile 10 sn kibarca kurutuldu 20 sn 800 mw/cm2 ışıkla polimerize edildi ve tüm seramikler sızıntı testine tabi tutuldu. Bulgular: Sızıntı testine tabi tutulmuş örneklerde marjinlerde ince bir çizgi şeklinde sızıntı izlenmiştir.Sonuç: Farklı yüzey işlemleri uygulanan örneklerde sızıntı değerleri arasında fark bulunamamıştır

Effect of Surface Treatments on Leakage of Zirconium Oxide Ceramics

Abstract

Objective: The aim of this pilot study was to compare the effects of pretreatments on leakage of zirconia ceramics. Materials and Methods: The speciments divided into 6 groups that were subsequently treated as follows: group 1, no treatment (control); group 2, the ceramic surfaces were airborne-particle abraded with 110 μm aluminum-oxide (Al2O3) particles; group 3, after abrasion of the surfaces with 110 μm Al2O3 particles, silica coating using 30 μm (Al2O3) particles modified by silica (rocatec system) and application of the silane coupling agent (espe-sil); group 4, ceramic surfaces irritated with neodymium-doped yttrium aluminium garnet (Nd:YAG) laser [fidelis plus 3 foton (Ljubljana, Slovenia)] at 20 hz, 100 mj, 2 w, 100 μs; group 5, ceramic surfaces irritated with Nd:YAG laser at fidelis plus 3 fotona (Ljubljana, Slovenia) at 20 hz, 100 mj, 2 w, 100 μs; group 6; application of a zirconia primer (z-prime plus bisco, IL, USA) agent. And all ceramics tested for leakage. Results: For marginal leakage, score 0 was found in all groups. Conclusion: No significant differences were found in marginal leakage under all conditions.
