“…33 Zirconia (ZrO 2 ) Several studies found that incorporating zirconia (ZrO 2 ) fillers in PMMA significantly increased its flexural strength. [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] However, a slight decrease in flexural strength was also reported; it may result from clustering of the particles within the resin, which weakened the material. 43 In addition, the impact strength, fracture toughness, and hardness of PMMA were increased significantly by incorporating ZrO 2 .…”

This paper reviews acrylic denture base resin enhancement during the past few decades. Specific attention is given to the effect of fiber, filler, and nanofiller addition on poly(methyl methacrylate) (PMMA) properties. The review is based on scientific reviews, papers, and abstracts, as well as studies concerning the effect of additives, fibers, fillers, and reinforcement materials on PMMA, published between 1974 and 2016. Many studies have reported improvement of PMMA denture base material with the addition of fillers, fibers, nanofiller, and hybrid reinforcement. However, most of the studies were limited to in vitro investigations without bioactivity and clinical implications. Considering the findings of the review, there is no ideal denture base material, but the properties of PMMA could be improved with some modifications, especially with silanized nanoparticle addition and a hybrid reinforcement system.

“…Polymethyl methacrylate, PMMA, is still widely used as denture base material due to its satisfactory esthetics, easy operation, low cost, and favorable stability in the oral environment 1,2) . However, poor mechanical property is one of the major shortcomings of PMMA denture base composites, which limits their potential use 3,4) .…”

The aim of this study was to investigate the hybrid effects of ZrO 2 nanoparticles (nano-ZrO 2 ) and aluminum borate whiskers (ABWs) on flexural strength and surface hardness of denture base resin, polymethyl methacrylate (PMMA). Both nano-ZrO 2 and ABWs were modified by silane coupling agent (Z6030) before being mixed with PMMA. Various amounts of silanized nano-ZrO 2 and ABWs were mixed with PMMA to prepare ZrO 2 -ABW/PMMA composites. Flexural strength and surface hardness were evaluated using threepoint bending test and Vickers hardness test respectively. Fractured surfaces were also observed by scanning electron microscopy (SEM). The mechanical behaviors of silanized ZrO 2 -ABW/PMMA composites were significantly improved. Flexural strength reached a maximum value of 108.01±5.54 MPa when 2 wt% of nano-ZrO 2 was mixed with ABWs at a ZrO 2 /ABW ratio of 1:2, amounting to an increase of 52% when compared with pure PMMA. Surface hardness achieved a maximum value of 22.50±0.86 MPa when 3 wt% of nano-ZrO 2 was mixed with ABWs at the same ZrO 2 /ABW ratio, which was an increase of 27% when compared with pure PMMA.

“…The maximal biting forces of a patient can reach up to 700 N, but these values are reduced (100-150 N) [25] with the removal of dentures. Denture fractures are essentially due to stress concentration and increased flexing [26] . Many authors found that the fracture toughness seems to be a suitable measurement to demonstrate the effects of resin modifications.…”

One way analysis of variance (ANOVA) and Tukey's tests were used for testing the significance between the means of tested groups which are statistically significant when the P value ≤ 0.05. Results: Addition of Zirconium oxide nanofillers to PMMA significantly increased the flexural strength, fracture toughness and hardness. Conclusion:These results indicate that Zirconium oxide nanofillers added to PMMA has a potential as a reliable denture base material with increased flexural strength, fracture toughness, and hardness. According to the results of the present study, the best mechanical properties were achieved by adding 7%wt ZrO 2 concentration.
