Abstract

Poly Methyl Methacrylate based restorations are widely accepted in dental and medical field due to
the excellent biocompatibility and easy fabrication, however these restorations exhibit inferior mechanical
properties. Therefore, the present study conducted to enhance the flexural strength of PMMA based material by
reinforcing conventional PMMA with poly propylene fiber. 10 different test groups were prepared by varying
the weight percentage (2.5, 5 & 10 Wt %) and aspect ratio (3mm/220μm, 6mm/220μm & 12mm/220μm) of the
poly propylene fibers. Results obtained were statistically analyzed using One – Way Anova followed by Tukey
Kramer multiple comparison test. All fiber reinforced test groups showed improved flexural strength and 6mm
long fiber in 2.5 Wt% showed the highest flexural strength among the fiber reinforced test groups.
