Flexural Strength Evaluation of Dental Post Prototype Contain ZAS-PMMA Composite Fiber with Electrospinning Methods

Abstract:

Composite fiber were already developed and looked promising in dentistry. PMMA, optically clear polymer, was combined with high mechanically properties ZrO2-Al2O3-SiO2 (ZAS) ceramic powder to improve the flexural strength value of dental post prototype. ZAS powder, with ratio 60:20:20, were first prepared via sol-gel technique. Afterwards, PMMA was dissolved in acetone then incorporate with ZAS powder 1% wt to gain ZAS-PMMA composite fiber via electrospinning method. Dental post prototype were fabricated into two groups, one group contain ZAS-PMMA composite fibers and one group contain neat BisGMA, as control, with amount of each groups samples was 10. As-prepared samples were tested by Universal Testing Machine (UTM) to evaluate the flexural strength values. 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 dental endodontic post in anterior.
