Abstract:

 AIM: The introduction of resin-based composite technology in restorative dentistry was one of the most significant investments in dentistry in the last century. Wear resistance continues to be a particularly important issue in the renovation of large occlusal areas in posterior teeth. The purpose of this study was to compare the wear of direct and indirect resin composites designed for in vitro posterior use. METHODS: Therefore, a total of 40 samples were prepared with three direct nanohybrid composites Tetric Evo Ceram, Filtek Supreme XT, Aelite Estetik and two indirect composites Estenia, Tescera ATL in a randomized complete block design n8. The samples were subjected to abrasive wear performed under a normal load of 5060 N with a frequency of 1.2 Hz on a wear simulator Selcuk in the presence of artificial saliva, after which superhard replicas of stone molds were produced analyze the laboratory attrition rate. Wear was quantified by optical 3-D scanning every 30,000 to 60,000 cycles. RESULTS: Data were analyzed by one-way ANOVA and Tukeys multiple range post hoc test α  0.05. The results showed that the type of composite resin significantly affects the measured wear. Direct nanohybrid composite resin material Aelite Esthetic showed significantly less abrasive wear than indirect microhybrid composite resin Tescera ATL and direct nanofilled composite resin Filtek superior. There was no significant difference in the average wear rate of Aelite Estetik, Estenia and Tetric Evo Ceram. CONCULUSION: In summary, indirect resin composites may not have superior wear behavior compared to direct nanohybrid composites. However, the laboratory resistance of all composite resin types was found to be adequate in this study when compared to the ADA approval program regulations.

 AMAÇ: Diş restorasyonlarında rezin bazlı kompozit teknolojisinin kullanılmaya başlanması, geçen yüzyılın diş hekimliğinde en büyük ilerlemedir. Posterior dişlerin geniş oklüzal alanlarının restorasyonunda kompozit rezinlerin aşınma direnci önemini korumaktadır. Bu çalışmanın amacı posterior restorasyonlar için direkt ve indirekt kompozitlerin laboratuvar aşınma değerlerini karşılaştırmaktır. GEREÇ VE YÖNTEMLER: Bu çalışma, 40 adet çürüksüz insan daimi azı dişi rastgele 3 nanohibrit direkt kompozit Tetric Evo Ceram, Filtek Supreme XT, Aelite Estetik ve 2 adet indirekt kompozit Estenia, Tescera ATL olmak üzere 5 gruba ayrıldı n8. Dişlerin okluzal bölgesinde düz dentin yüzeyi oluşturularak 2 mm kalınlığında kompozit malzeme ile restore edildi. Numuneler, yapay tükürük varlığında bir aşınma simülatörü kullanılarak 1.2 Hz frekansta ve 50-60 N normal yükte aşınmaya tabi tutuldu. 30.000 ve 60.000 aşındırma döngüsünden sonra numunelerden sert sıva kopyaları yapıldı. BULGULAR: Hazırlanan alçı modeli optik 3 boyutlu tarama kullanılarak tarandı ve aşınma değerleri hesaplandı. Veriler, tek yönlü varyans analizi ANOVA ve Tukey çoklu karşılaştırma testi kullanılarak analiz edildi α0.05. Sonuç olarak kompozit rezin tipinin aşınma derecesini büyük ölçüde etkilediği tespit edildi. Doğrudan nanohibrit kompozit rezin malzemesinin Aelite Esthetic, dolaylı mikrohibrit kompozit rezin Tescera ATL ve doğrudan nano dolgulu kompozit rezine Filtek Supreme göre önemli ölçüde daha az aşınma sergilediği gösterilmiştir. Aelite Esthetic, Estenia ve Tetric Evo Ceram ortalama aşınma seviyeleri açısından önemli bir farklılık göstermedi. SONUÇ: Sonuç olarak dolaylı kompozitlerin aşınma direnci açısından doğrudan kompozitlerden üstün olmadığı görüldü. Ancak bu çalışmada kullanılan tüm kompozit rezin malzemelerin aşınma direncinin ADA Onaylı Program hükümlerine göre yeterli olduğu söylenebilir.
