“…Improving mechanical properties of acrylic denture bases by addition particulate fillers have been studied by many researches. There are several studies showed that addition of metal oxides decreased the tensile strength and others demonstrated improvement in flexural strength . Zuccari et al evaluated the effect of Al 2 O 3 , MgO, and ZrO 2 to reinforce acrylic resins.…”

Polymethyl methacrylate-zinc oxide (PMMA/ZnO) nanocomposites with different ZnO morphology and quantities were prepared by in situ curing of MMA/PMMA used in denture base material in the presence of ZnO nanostructured materials. The composition, structure, and morphology of the nanocomposites were characterized by Fourier-Transform infrared spectra (FT-IR), X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and thermogravimetric analysis (TGA). The effect of ZnO morphology and contents on the mechanical properties including impact, flexural, and hardness was studied. The results demonstrated that the mechanical and thermal properties of denture base materials were improved by incorporation of nano-sized ZnO into the polymethyl methacrylate matrix. The impact strength was highly improved upon using ZnO nanotubes. However, the flexural strength was improved using ZnO nanospheres.

“…The denture base materials can be strengthened to prevent fractures which is a common complication. There are some studies that have evaluated the effect of reinforcement of PMMA with different materials, but the those on the reinforcement of polyamide resin are scarce ( 7 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 33 ). In a previous study, the rigidity of dentures made of polyamide, polyester and conventional heat-polymerized PMMA were compared, and it was concluded that the polyamide, which has low elasticity, needed to be reinforced with metal frames ( 37 ).…”

“…Different methods have been developed to overcome these disadvantages such as; adding filling materials to reinforce of resins, chemical modifications of polymer with copolymerization and cross-linking of resin materials, producing new materials with different polymerization technics ( 6 , 7 , 8 ). Strengthening materials such as glass fiber, aramid fiber, nanodiamond powder, zirconium oxide, aluminum oxide, halloysite nanotubes, metal wires and carbon nanotubes can be added to denture base in order to increase fatigue resistance and fracture resistance of the prosthetic base materials ( 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ). However, the most effective reinforcement is yet to be determined ( 18 ).…”

The aim of this study was to evaluate flexural strength, elastic modulus and dynamic mechanical analysis (DMA) of heat-polymerized polymethyl methacrylate resin, polyamide resin and glass fiber-reinforced polyamide resin. Materials and MethodsThree groups were determined according to denture base materials as polymethyl methacrylate resin (H), polyamide resin (P) and glass fiber reinforced polyamide resin (R). Sixteen specimens for each denture base material were prepared with dimensions of 64x10x3.3 mm for three-point bending test. Two specimens for each denture base material were prepared with dimensions of 30x10x3 mm for DMA. Polymethyl methacrylate and polyamide specimens were prepared according to the manufacturer's recommendations. The silane was applied to glass fibers (4.5 mm length) 2% by weight of the polyamide resin, they were placed in polyamide resin cartilages and injected to the mold. The thermal aging procedure was applied to half of specimens of each material (n=8). Flexural strength and elastic modulus of the specimens were determined by three-point bending test at a speed of 5 mm/ min. DMA was performed to 1 specimen from each group to evaluate viscoelastic properties. Data were analyzed with one-way ANOVA, Tukey and Paired t tests. ResultsA statistically significant difference was found in flexural strength and elastic modulus values of denture base materials (p=0.00). The highest flexural strength and elastic modulus values were observed in polymethyl methacrylate group. There was no significant difference between polyamide and glass-fiber reinforced polyamide groups (p=0.497). No significant difference was determined in all threedenture base materials before and after aging procedure. ConclusionThe reinforcement with glass-fibers did not affect the flexural strength and elastic modulus of polyamide resin.
