The integration of dental resins with highly drawn polyethylene fibres

This paper presents an initial study of an ongoing project on the reinforcement of acrylic denture base material with continuous, highly drawn linear polyethylene fibres. The mechanisms of integration of the fibres with various dental resins are investigated using pull-out techniques, complemented with observations made in deliberately broken reinforced denture bases. Attention is given to the effect of temperature and humidity to mimic the conditions of the oral environment.
