Study the Influence of Zirconium Oxide Nanofillers on the Transverse and Impact Stresses of Heat-Cure Acrylic Resin Polymerization

Abstract

Abstract Objective: Despite being the more material widely using in dental field for the construction of removable prosthesis base, it is not sufficient for meet ideal functional requirement for dental restorations. Purpose: The goal of this research was to see how various concentrations of zirconium oxide (ZrO2) nanofiller powder (2%, 4%, 6%, & 8%) affected the transverse and impact strengths of hot-cured polymer resin polymerization. Procedure: ZrO2 powder samples of various doses (2%, 4%, 6%, & 8%) are embedded within hot-cured acrylic resin as well as handled under optimized conditions (L/P ratio of 1:3 (by volume), traditional packing process, and short curing cycle (90 minutes with 74 ºC then for 30 minutes with 100 ºC) was using to fabricate samples of PMMA of dimensions (65 x 10 x 2.5 mm) for the transverse strength and (60 x 7 x 4mm) for the impact strength. Polymethyl methacrylate with no additives has been prepared as an original approach. All specimens had been exposed to two types of mechanical examinations: transverse stress and impact stress. Transverse stress (MPa) in addition to impact stress (J) values are collect, tabulated, as well as statistical analyze. To evaluate significant among range for the experimental samples, each ANOVA as well as Tukey's examinations are being used, that are statistical significance whenever the probability values are 0.05. Results: The adding of ZrO2 nanofillers for polymethyl methacrylate elevated its transverse and impact strengths significantly. Conclusion: Polymethyl methacrylate and zirconium oxide nanofillers does have the possibility to serve as a credible denture base material with increased transverse and impact strengths. Material characteristics have been enhanced by incorporating 8% weight percent ZrO2 concentration, according to the report's findings.
