Rheological properties of experimental Bis-GMA/TEGDMA flowable resin composites with various macrofiller/microfiller ratio

Light transmittance and polymerization kinetics of amorphous calcium phosphate composites

“…Another contributing factor for the observed differences in kinetic behavior may have been comparatively larger particles of ACP filler (Fig. 6), which had lower surface area in contact with the resin thus allowing better mobility [28,29]. In any case, all of the ACP composites showed similar duration of the linear transmittance rise ( Table 2), demonstrating that the addition of 10 % of silanized fillers did not considerably affect their kinetic behavior.…”

<i>In vitro</i>/<i>in silico</i> investigation of failure criteria to predict flexural strength of composite resins

“…The other slight difference at 31.2 vol% suggests that the material characteristics of CR shifted from brittle to ductile behavior, with a nonlinear load-deflection curve. Assuming the intended endproduct use is in the clinic, the contents of fillers used in this study ranged from 20 to 80 vol% because lower and higher filler contents have differing viscosities 14,27) and lead to unsatisfactory handling properties of CR before light curing. In addition, higher filler contents exhibit lower fatigue resistance 28) .…”

Effect of the functionalization of silica nanoparticles as a reinforcing agent on dental composite materials

“…They have also focused on the effect of particle size and particle concentration in the performance of restored materials [19,20]. Another important area of investigation is the use of nanoparticles to improve composite material performance, due to their large surface area.…”
