“…It was observed that the number of cohesive failures within FRC tended to increase as higher shear bond strength values were yielded. Results of this study were in accordance with previous studies which showed changes in fracture pattern owing to the addition of FRC to the interface 14,17,18) . Fennis et al investigated the effect of FRC on the fracture resistance of cusp-replacing composite restorations, whereby it was concluded that glass FRCs had a beneficial effect on the failure mode and thereby on re-restorability in the event of a fracture 18) .…”

“…Indeed, previous studies had demonstrated the ability of glass fibers to withstand tensile stress and stop crack propagation in composite materials 15,16) . However, only a few studies have examined the effect of FRC layer at the tooth-resin composite interface 10,11,17,18) . Moreover, none of the published research has investigated the effect of silicon forming aids, which were developed for forming and positioning fibers to their right positions in clinical applications.…”

Effect of fiber-reinforced composite at the interface on bonding of resin core system to dentin

et al. 2008

The aim of this study was to evaluate the effect of fiber-reinforced composite (FRC) at the interface on bonding of resin core systems to bovine dentin using different adhesive systems. To this end, the labial surfaces of 60 bovine incisors were ground to obtain flat dentin surfaces and then divided into two groups according to the adhesive system used: total-etching (Solobond Plus) versus self-etching (Clearfil SE Bond). Resin core systems were bonded to tooth structure either without or with a FRC layer (everStick Net, StickTech). For groups with FRC layer, a silicon forming aid was used to adapt the latter on the dentin surfaces. After resin core was polymerized with Optilux 501 for 40 seconds, the specimens were tested in a universal testing machine. ANOVA revealed that presence of FRC at the interface had a significantly positive effect on bond strength (p<0.001). However, differences between groups were not significant for either adhesive system (p = 0.076) or with the use of silicon forming aid (p = 0.348).

“…Due to the anisotropy of FRC material, its failure behavior has been known to be very complex. Previous reports have attributed the complex failure behavior to a change in the interface dynamics, whereby the latter resulted from the fibers added to the tooth-restoration interface 18,29) . The results of the current study were in good agreement with previous reports, which showed changes in failure mode despite the lack of increase in static adhesive strength 18,21,29,30) .…”

Effect of fiber-reinforced composites on the failure load and failure mode of composite veneers

et al. 2009

This study compared the initial and final failure loads and failure modes of indirect resin composite laminate veneers with and without fiber reinforcement. Forty intact lower canines received standard laminate preparations and were randomly assigned into four test groups (n=10). In Group 1, indirect resin composite veneers were repaired with two layers of preimpregnated bidirectional glass fiber weave and a restorative composite; in Group 2, with a layer of preimpregnated unidirectional glass fibers and a restorative composite; and in Group 3, with an experimental semi-IPN matrix composed of multidirectional short glass fibers. Indirect resin composite veneers without any fiber reinforcement were used as control (Group 4). All specimens were thermocycled and tested with a universal testing machine. On the final failure load, there were no statistically significant differences (p>0.05) among the test groups. Within each group, pairwise comparison of initial and final failure loads revealed statistically significant differences (p<0.05), except for Group 4 (p>0.05). On failure mode, unreinforced specimens showed instantaneous failure, whereas reinforced specimens mostly demonstrated elongated failure.

Bu in vitro çalışmanın amacı; fiberle güçlendirmenin, nanofil kompozit materyalinin eğme direncine etkisinin araştırılmasıdır. Materyal ve Metod: Eğme direnci testi için ISO 4049 standartlarına uygun hazırlanan standart bir metal kalıp (2 ×2 ×25 mm) kullanılarak 60 örnek hazırlandı. Örnekler dört çalışma grubuna ayrıldı (n:15). Akışkan Kompozit (Filtek Flow)+Nanofil Kompozit (Filtek Supreme) (Grup I), Nanofil Kompozit (Kontrol) (Grup II), Akışkan Kompozit+Örgü Cam Fiber (Ever-Stick Net)+Nanofil Kompozit (Grup III), Örgü Cam Fiber+Nanofil Kompozit (Grup IV). Örnekler 24 saat 37 0 C de distile suda bekletildi. Daha sonra Universal Test cihazı ile üç nokta eğilme testine tabi tutuldu. Veriler istatistiksel olarak Kruskall Vallis ve Mann Whitney U testi kullanılarak analiz edildi. Her gruba ait üç örnek, taramalı elektron mikroskobunda (SEM) incelendi. Bulgular: Ortalama eğme direnci değerleri ve standart sapmaları Grup I, II, III ve IV de sırasıyla 93.6±4, 85.5±6, 107±9 ve 101±5 bulundu. Diğer gruplarla karşılaştırıldığında kontrol grubunun (Gr II) en düşük değere sahip olduğu belirlenirken en yüksek eğme direncinin akışkan kompozit ile beraber fiber uygulanan nanofil kompozit grubunda olduğu gözlendi (p<0.05). Kontrol grubu ile diğer gruplar arasında eğme direnci değerlerinin anlamlı bir farklılık gösterdiği belirlendi (p<0.05). Örnekler SEM ile incelendiğinde, fiber ile güçlendirilmiş gruplarda (GR III ve IV) meydana gelen kırılmanın gerilim bölgesine yerleştirilen fiberle sınırlı kaldığı saptandı. Sonuç: Bu in vitro çalışmanın sınırları içinde cam fiberle güçlendirmenin, nanofil kompozitin eğme direncini arttırdığı sonucuna varıldı. Örneklerde kırılmanın, gerilim bölgesinde fiberle sınırlı kaldığı; cam fiberin kırık stoperi olarak işlev yaptığı sonucuna varıldı.
