Bulk-fill Kompozit Rezinlerin Antagonist Çelik Top ve CAD/CAM-Blok Karşısında Aşınma Dirençlerinin KarşılaştırılmasıEzgi Altuntaş1, Selinsu Öztürk1, Ayşe Aslı Şenol1, Erkut Kahramanoğlu2, Pınar Yılmaz Atalı1, Cafer Türkmen11Marmara Üniversitesi Diş Hekimliği Fakültesi, Restoratif Diş Tedavisi Anabilim Dalı2Marmara Üniversitesi Diş Hekimliği Fakültesi, Protetik Diş Tedavisi Anabilim DalıAMAÇKompozit rezinler, antagonist materyal tarafından mekanik kuvvetlere maruz kaldığında aşınmaktadır. Aşınma sonucu mekanik özellikleri azalmakta, bu nedenle uzun süreli klinik başarıları olumsuz etkilenmektedir. Bu çalışmanın amacı iki farklı bulk-fill kompozit rezinin çelik top ve cad/cam blok karşısında aşınma dirençlerinin karşılaştırılmasıdır.GEREÇLER ve YÖNTEMLERVisCalor-Bulk (VOCO) ve SonicFill 2 (Kerr) bulk-fill kompozitler ile4x10mm boyutlarında 32 adet kompozit disk hazırlandı. Kompozit diskler 20 saniye boyunca VALO (Ultradent) ile polimerize edildi. 4 farklı grene sahip cila diskleri ile cilaları tamamlandık sonra37°C distile suda 24 saat boyunca bekletildi. Örnekler randomize olarak kompozitlere göre 2 gruba ayrıldıktan sonra antagonist materyale göre de 2 alt gruba (n=8) ayrıldılar; Grup-1-VisCalor-Steel (VS), Grup-2-VisCalor-CAD (VC), Grup-3-Sonicfill-Steel (SS), Grup-4-Sonicfill-CAD (SC).Ağız ortamını taklit edebilmek için örneklere termal döngü (5-55°C) ile birlikte dual akslı çiğneme simülatöründe iki gövdeli aşınma testi (120,000 cycles, 49N) (C-S-4; SD-Mechatronik Company) uygulandı. Örnekler, yüklemeden önce ve sonra lazer tarayıcı (LAS-20, SD Mekatronik) ile tarandı. Geomagic programı kullanılarak gruplar arası hacimsel aşınma miktarı analiz edildi.Her gruptan rastgele seçilen bir örnek, taramalı elektron mikroskobu altında değerlendirildi. Veriler iki yönlü ANOVA testi ile incelendi(p=0.05).
Comparison of Abrasion Resistance of Bulk-fill Composite Resins Against Antagonist Steel Ball and CAD/CAM-BlockEzgi Altuntaş1, Selinsu Öztürk1, Ayşe Aslı Şenol1, Erkut Kahramanoğlu2, Pınar Yılmaz Atalı1, Cafer Türkmen11Marmara University Faculty of Dentistry, Department of Restorative Dentistry2 Marmara University Faculty of Dentistry, Department of ProsthodonticsAIMComposite resins erode when subjected to mechanical forces by the antagonist material. As a result of wear, its mechanical properties decrease, therefore, its long-term clinical success is adversely affected. The aim of this study is to compare the wear resistance of two different bulk-fill composite resins against steel ball and cad/cam block.MATERIAL and METHODS32 composite discs of 4x10mm dimensions were prepared with VisCalor-Bulk (VOCO) and SonicFill 2 (Kerr) bulk-fill composites. Composite discs were polymerized with VALO (Ultradent) for 20 seconds. The polishing was completed with polishing discs with 4 different grains, and then they were kept in distilled water at 37°C for 24 hours. After the samples were randomly divided into 2 groups according to the composites, they were divided into 2 subgroups (n=8) according to the antagonist material; Group-1-VisCalor-Steel (VS), Group-2-VisCalor-CAD (VC), Group-3-Sonicfill-Steel (SS), Group-4-Sonicfill-CAD (SC). In order to mimic the oral environment, the specimens were subjected to a two-body abrasion test (120,000 cycles, 49N) (C-S-4; SD-Mechatronic Company) in a dual-axle chewing simulator with thermal cycling (5-55°C). Samples were scanned with a laser scanner (LAS-20, SD Mechatronics) before and after loading. Intergroup volumetric wear was analyzed using the Geomagic program. A randomly selected sample from each group was evaluated under a scanning electron microscope. Data were analyzed with two-way ANOVA test (p=0.05).
