Abstract

Aim: The aim of this study was to determine the dimensi-onal accuracies of two different denture base polymers that were reinforced with glass fibers in chopped form. Material and Methods: Five rhombic plates were prepared with reference point. 10 heat-cured acrylic (5 control, 5 reinforced) and 10 injection system's acrylic resins (5 control, 5 reinforced) test specimens were produced using these brass models. The dimensional changes of control and fiber reinforced specimens after processing, drying for 4 day at 37 °C, and storage in 37 °C water for 15 and 30 days were calculated by the change of the distance vector. Results: Fiber reinforcement with 8mm, %5 glass fiber did not effect dimensional accuracy of both acrylic resins significantly. Conclusion: Although fiber reinforcement required extra monomer, dimensional stability of test specimens was not affected.

Özet

Amaç: Bu çalışmanın amacı kırpılmış formda cam fiberle güçlendirilmiş iki farklı akrilik rezinin boyutsal stabilitelerini değerlendirmekti. Materyal ve Yöntem: Referans noktaları içeren 5 adet dikdörtgen pirinç plak hazırlandı. Bu pirinç plaklardan 10 adet ısıyla polimerize olan (5'i kontrol, 5'i fiberli), 10 adet ise enjeksiyon sistem akrilik rezininden (5'i kontrol 5'i fiberli) test örnekleri hazırlandı. Kontrol ve fiberli grupların boyutsal değişimleri, örneklerin yapım sonrası, 4 gün 37 °C'de kurutma sonrası, 15 ve 30 gün 37 °C'de suda bekletme sonrası vektörel boyut değişimleri dikkate alınarak hesaplandı. Bulgular: 8 mm, %5 oranında fiber ilavesinin her iki akrilik rezinin boyutsal değişimleri üzerine anlamlı bir etkisi bulunamadı. Sonuç: Fiber güçlendirmesi daha fazla monomer ilavesi gerektirmesine rağmen, test örneklerinin boyutsal stabilitesi etkilenmemiştir.
