“…It was found that adding TiO 2 particles could improve the flexure strength, fracture toughness, hardness of PMMA, 26,40,57,58 as well as thermal conductivity. 33 In addition, a significant increase in impact strength 59 and a significant decrease in water sorption and solubility were found upon addition of TiO 2 to PMMA. 26 Conversely, some studies found that TiO 2 did not improve the flexure strength of PMMA, which could be attributed to clustering of the particles within the resin, causing its weakness.…”

“…67 In addition, silver-reinforced PMMA resin has increased flexural and fatigue strength and improved thermal conductivity. 32,33 However, it was found that incorporating 0.5% of antimicrobial silver-zinc zeolite in heat-cured acrylic resin did not affect its impact and transverse strength, the surface hardness, and the surface roughness of the resin. It did not change its color, but a significant decrease in water sorption and an increase in water solubility were found in the acrylic resin.…”

“…25,[30][31][32][33] In addition, reinforcing PMMA with aluminum increased the flexural strength, impact strength, tensile strength, compressive strength, and surface hardness of the resin. 26,30,32,34 Warpage also decreased significantly after addition of aluminum to PMMA.…”

“…38 Although the addition of Al 2 O 3 to PMMA significantly increased thermal conductivity, the flexural strength values of PMMA were not significantly changed. 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.…”

“…42 Also, addition of ZrO 2 significantly increased the thermal conductivity of PMMA. 33 Different results were obtained regarding the effect of ZrO 2 on the water sorption and solubility of PMMA. It was found that adding ZrO 2 significantly decreased the water sorption and solubility of PMMA, 26 while an insignificant difference in water solubility and an increase in water sorption within the limit of ADA specifications were also reported.…”

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.
