摘要

Composite fibers have been developed and seem to be promising in dentistry. PMMA, optically clear polymer, was combined with higher mechanical properties ZrO2-Al2O3-SiO2 (ZAS) ceramic powder to improve the flexural strength value of dental post prototype. ZAS powders, with the ratio of 60:20:20, were first prepared via sol-gel technique. Afterward, PMMA was dissolved in acetone then incorporated with ZAS powder 1% wt to gain ZAS-PMMA composite fiber using electrospinning method. Dental posts prototype were fabricated into two groups, one group contained ZAS-PMMA composite fibers and another group contain neat BisGMA, as control, with an amount of each groups samples was 10. As-prepared samples were tested by Universal Testing Machine (UTM) to evaluate the flexural strength values. The result showed ZAS-PMMA composite fiber post and neat BisGma post had mean value 68,71 Mpa and 46,37 Mpa respectively. Based on unpaired T-test analysis (p-value < 0.05), the composite fiber post is significantly higher (48.17 %) than the neat BisGMA post. ZAS-PMMA composite fiber post was potential to be used as a dental endodontic post in anterior.
