Abstract

Amaç: Kompozit rezinler uzun yıllardır hem
restoratif dolgu maddesi olarak hem de 
adeziv restorasyonlarda diş eksikliklerinin giderilmesinde
kullanılmaktadır. Artan okluzal yükler karşısında  kompozit rezinlerin fiber ile güçlendirilmesi
materyalin dayanıklılığını artırmak amacı ile kullanılan bir yöntemdir. Bu invitro çalışmanın amacı fiber ile
güçlendirmenin kompozit rezinlerde eğilme direncine olan etkisinin
araştırılmasıdır.

Gereç ve Yöntem: Farklı fiber
dağılımına ve rezin oranına sahip 
kompozit bloklar (GR 1, GR 2, GR 3,) ve bir deneysel kompozit (GR 4)
laboratuvar ortamında hazırlandı. Fiber ile güçlendirilmiş bloklar ve piyasada
yer alan hazır kompozit blok (GR 5) kesme cihazı ile ebadı 2x2x25 mm olacak
şekilde 5 gruba (n:18) ayrıldı. Örneklere 24 saat 37 C de distile suda
bekletildikten sonra Universal test cihazında  
1mm/dk hızla  eğilme testi
uygulandı. Sonuçlar  tek yönlü varyans
analizi (ANOVA) ile değerlendirildi. 

Bulgular: Tüm gruplar arasında
istatiksel olarak anlamlı farklılık gözlenmiştir (p<0.001). Ortalama eğilme
direnci değerleri ve standart sapmaları GR 1, GR 2, GR 3, GR 4 ve GR 5’de
sırasıyla 130±6, 125±5.1, 136±6.8, 115±4 ve 85±2.9 bulundu.  Gr 3 en yüksek değeri gösterirken, Gr 5 en
düşük değeri göstermiştir (p<0.001).

Sonuç: Bu invitro çalışmada kompozit rezinlerin cam fiber ile güçlendirilmesi
eğilme direncini artırmaktadır.









Anahtar kelimeler: Kompozit rezin, fiber, eğilme direnc



DOES FIBER REINFORCEMENT
EFFECT ON FLEXURAL STRENGTH OF COMPOSITE RESINS?
ABSTRACT



 



Aim: Composite resins have
been used for many years both as a restorative material and adhesive
restorations on the loss of tooth structure. Fiber reinforcement is the most
commonly used method for increasing the strength of the composite materials
under increased occlusal forces. The aim of this in vitro study was to
investigate the effect of fiber reinforcement of composite resins for their
flexural strength.



Material
and Methods:
  Composite blocks (GR 1, GR 2, GR 3,) which
have different fiber configurations/ resin ratio and experimental composite (GR
4) were prepared in laboratory condition. Fiber reinforced composite blocks and
commercial available composite blocks (GR 5) were cut into small specimens
(2x2x 25mm) into 5 subgroups (n:18). The specimens were stored in distilled
water at 370 C
for 24 hour, and then flexural strength tests were performed with using
Universal Testing Machine. Data were analyzed using one-way ANOVA.



Results: Significant differences
were found among the flexural strength of the tested groups (p<0.001).  The mean flexural strength values of the GR
1, GR 2, GR 3, GR 4 and GR 5 were 130±6, 125±5.1, 136±6.8, 115±4 and 85±2.9
respectively.  GR 3 exhibited the highest
flexural strength values in comparison to the other groups (p<0.001). While
control group (Gr 5) exhibited the lowest.



Conclusion:
It
is concluded that glass fiber reinforcement improves the flexural strength of
composite resins.



Key words: Composite resin, fiber, flexural strength
