“…The use of carbon fibres as denture-base strengtheners has been investigated in a number of studies (Schreiber, 1971;Wylegala, 1973;Skirvin, Vermilyea & Brady, 1982;Kilfoil, Hesby & Pelleu, 1983;Bowman & Manley, 1984;DeBoer, Vermilyea & Brady, 1984), and it has been shown that they strengthen the resin. However, carbon fibres also have several properties that are undesirable in prosthetic constructions, e.g.…”

The effect of different metal and fibre strengtheners on the fracture resistance of polymethylmethacrylate was tested. Different types of commonly used metal wire and glass fibre, as well as carbon and aramid fibres, were used as strengtheners in test specimens. There were 21 groups, and each group contained 12 test specimens. Each metal strengthener had a beneficial effect on the fracture resistance of the polymethylmethacrylate (P less than 0.001-0.01). Some fibres, which were silanized for better adhesion, also had strengthening properties.

“…15 However, addition of steel fibers, glass fibers, carbon fibers, and titanium fibers improves the mechanical strength, [16][17][18] while PMMA matrix interspersed with rubber particles can increase the fracture toughness of the material. 19 Embedded stainless steel coil increases the compressive strength of the material, 20 but the steel coils may interfere with its usefulness as a reconstructive material in dentulous sites.…”

“…Based on the extent of the fibre composite reinforcement of the denture base, two types of reinforcement have been described in the literature (Schreiber 1971;Bowman & Manley 1984). Recently, these types of reinforcements were defined as total fibre reinforcement (TFR) and partial fibre reinforcement (PFR) (Vallittu 1997).…”

The aim of this study was to determine the tensile strength and E-modulus of unidirectional denture glass fibre-polymethyl methacrylate (GF-PMMA) composite with various fibre contents. The experimental values of tensile strength and E-modulus were compared with values obtained by a theoretical calculation. Autopolymerized PMMA test specimens (n = 6, per group) were reinforced with unidirectional E-glass fibres which had been wetted in a mixture of PMMA powder and monomer liquid. After storing the test specimens for 40 days in water at 37 degrees C, the tensile strength and E-modulus of the test specimens were measured. The increased amount of fibres in the PMMA matrix (up to 14.8% by weight) increased the mean tensile strength of the test specimens from 40.5 MPa to 91.2 MPa (P < 0.001) and the E-modulus from 2057 MPa to 3751 MPa (P < 0.001). The experimental tensile strength and Emodulus values were considerably lower than those based on the theoretical calculations. This was assumed to be due to the percentage of glass fibres unimpregnated with the PMMA resin. The presence of unimpregnated glass fibres was determined using light microscopy. The results of this study suggest that a new method of incorporating the glass fibres into the PMMA resin matrix should be developed in order to obtain a well-impregnated fibre composite reinforcement with high durability.
