Transverse strength of acrylic resin denture base material after the addition of different fibres

ABSTRACT

The aim of the present study was to investigate the effect of addition of different types of fibres on the transverse strength of acrylic resin denture base material. The addition of glass fibres [strand] and polyethylene fibres produced a non significant increase in the modulus of elasticity, compared with the control of conventional heat-cured acrylic resin. The addition of glass fibres [woven and strand], polyethylene and carbon fibres to acrylic resin produced a non significant increase in the modulus of rupture. Within the limitations of this study the addition of silk fibres did not produce an improvement in the mechanical properties
