Abstract

Denture base made from acrylic resin (polymethyl methacrylate, PMMA) was reinforced by different contents of ultrahigh-modulus polyethylene fiber (UHMPEF). The flexural strength of the denture base was tested, the failure modes and microstructures were investigated with a scanning electron microscope (SEM). The results indicate that 3.5wt% UHMPEF increased the ultimate flexural strength of the denture base.
