effect of carbon-graphite fiber reinforcement patterns on the transverse strength of provisional crown and fixed partial denture resins

ABSTRACT

This study was conducted to evaluate the effect of incorporating varying amounts [5, 10 and 15 wt%] of saline treated carbon-graphite fibers, in two different arrangement patterns, on the transverse strength of two provisional crown and fixed partial denture resins. Thirty five specimens of each resin were produced, 30 resin specimens were reinforced in linear and criss-cross fiber patterns with varying weight percentage of fiber contents. The mean transverse strength of the two resins increased significantly with 5 and 10 wt% fiber incorporation, but the differences in strength between 10 and 15 wt% were not statistically significant. The results obtained from this study showed promise of potentially practical techniques for strengthening provisional fixed partial dentures
