“…Consequently, better food sensation and healthier oral mucosa were expected by adding metal fillers to denture base resin. [25][26][27] Recently, the incorporation of nanofillers (Table 2) has been suggested to improve PMMA properties. The high surface area, fine size, and homogenous distribution of nanofillers improved the thermal properties of PMMA and increased its thermal stability compared with pure PMMA.…”

“…Also, addition of 10wt% and 20wt% silane-treated silver fillers enhanced the tensile and flexural strength of PMMA. 25 Addition of silver powder to PMMA significantly increased thermal conductivity; the flexural strength values of PMMA were not significantly changed. 33 The physical and mechanical properties of PMMA were enhanced by the addition of silver NPs, including improvement of thermal conductivity and compressive strength.…”

“…36,37 Also, silane-treated aluminum particles significantly increased the compressive, tensile, and flexural strength and the wear resistance of reinforced denture base resin. 25,37 Surface roughness and water sorption were not significantly changed with aluminum-reinforced denture resin. 31,35 However, one study found a significant decrease in water sorption and solubility after addition of Al 2 O 3 , 26 and an increase in water sorption was found by another study.…”

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.

“…It was stated that treating nano-fillers with silane coupling agent increased the chemical bond between the filler and acrylic resin (17) and increased the flexural properties of acrylic resin. In addition, silane-treated aluminum particles significantly increased the compressive, tensile, and flexural strength and the wear resistance of reinforced denture base resin (33,49,50) .…”

Purpose: This study was conducted to evaluate the effect of rein forcement of different concentrations of nano-ZrO 2 and nano-Al 2 O 3 on the flexural strength and impact strength of repaired acrylic resin denture bases. Materials and Methods: A total of 100 specimens were prepared from heat-polymerized acrylic resin and then they were equally divided for the flexural and impact strength tests. 50 specimens were assigned for each testing group. For the flexural strength testing, metallic rectangular molds with rectangular-shaped (65 mm length x10 mm width x 2.5 mm thickness) were prepared. While specimens for the impact strength testing were prepared using rectangular-shaped molds with dimensions of (50 mm length x6mm width x4mm thickness). The prepared intact specimens were cut vertically in two halves along their long axis. For the flexural and impact strength testing, a repair gap was done. Specimens for each strength test were divided into one control group (specimen repaired with autopolymerizing acrylic resin with no fillers) and two repair groups with 2 concentrations (2% and 5%) of nano-ZrO 2 fillers and two repair groups with 2 concentrations (2% and 5%) of nano-Al 2 O 3 fillers. Flexural strength was measured using an Instron mechanical testing machine and impact strength was measured by Izod impact tester. Results: For the flexural strength results, the highest flexural strength was recorded with the 5% nano-ZrO 2 fillers repair group followed by the 2% nanoZrO 2 group which also recorded higher significant mean value than the control group. In both nano-Al 2 O 3 groups, there was a highly significant reduction in the flexural strength for both concentrations. For the impact strength results, the highest impact strength was recorded for the 2% nanoZrO 2 fillers repair group followed by the 5% nano-ZrO 2 group which also recorded higher significant mean values than the control group. In the 2% nano-Al 2 O 3 repair group, there was a non-significant difference in the impact strength mean values compared with the control group. While the repair group reinforced with 5% nano-Al 2 O 3 showed significant reduction in impact strength. Conclusions:The incorpora tion of nano-ZrO 2 into repair resins may improve the flexural and impact strength of the repaired denture base whereas nano-Al 2 O 3 caused reduction of both strengths.
