“…However, the surface roughness of both acrylic resins was similar. Additionally, some studies reported that the different concentration of pigments and addition of fibres altered the physical properties of acrylic resins 27,28 . In general, N1 sclera resin exhibited statistically lower microhardness value when compared with colourless resin (Tables 2 and 3, Fig.…”

Placement of the GFF close to the tensile stress side surface of the bar increased the resistance to elastic deformation (i.e., higher MOE or stiffness) and the stress level needed for flexural fracture (i.e., higher FS). In addition, more energy was absorbed by reinforced specimens before fracture occurred (i.e., higher toughness). Localized reinforcement targeting tensile stress centers is thus a practical way to improve clinical durability of dentures against intra- and extraoral fracture.

“…By contrast, glass fibres have a better potential for provisional restorations, despite the difficulty of achieving adequate impregnation of the fibres with PMMA. 2,12 Some investigators have found that the increase in the flexural properties of denture base polymer reinforced with ultra-high modulus polyethylene (UHMPE) was insignificant [13][14][15] or smaller than the increase with the glass-fibre reinforcement. 16 Silanated glass fibres might be the fibres of choice for reinforcing denture base polymers because of the well-documented improvements in flexural properties and fatigue resistance associated with their use, as well as their good aesthetic quality.…”

Background: In recent years, glass fibres have been used to strengthen denture base resins. A major difficulty in using reinforcing fibres with multiphase acrylic resins, such as powder liquid resins, is inadequate impregnation of the fibres with the resin. Methods: This investigation examined the reinforcing effect of glass fibres on the fracture resistance and flexural strength of acrylic denture base resins. Eighty identical specimens were formed in specially designed moulds in accordance with the manufacturer's recommendations. The four experimental groups were prepared and these consisted of conventional acrylic resin and the same resin reinforced with glass fibres. Ten specimens were fabricated in a standardized fashion for each experimental group. Flexural strength was tested using a 3‐point universal testing machine. Results: In this study, statistically significant differences were found in the flexural strength of the specimens (P<0.05). The injection‐moulded, fibre‐reinforced group had significantly lower flexural strength than the injection‐moulded group (P<0.001), and the microwave‐moulded, fibre‐reinforced group had lower flexural strength than the microwave‐moulded group. The fracture resistance was significantly higher in the injection‐moulded, fibre‐reinforced group than in the injection‐moulded group (P<0.05), and the fracture resistance was significantly higher in the microwave‐moulded, fibre‐reinforced group than in the microwave‐moulded group. Conclusion: Within the limitations of this study, the flexural strength of heat‐polymerized PMMA denture resin was improved after reinforcement with glass fibres. It may be possible to apply these results to distal extension partial and complete denture bases.
