Comparison of Transverse Strength of Conventional Denture Base Resin and Reinforced Denture Base Resin with Glass Fibres and Polypropylene Fibres in Concentration of 1 wt% and 2 wt% - An in Vitro Study

The transverse strength of denture base resin is of great concern and many approaches have been used to strengthen acrylic resin dentures. The objectives of this study were two fold: Firstly, to compare the transverse strength of conventional denture base resin and denture base resin reinforced with 1wt% and 2wt% glass fibres; secondly, to compare the transverse strength of conventional denture base resin and denture base resin reinforced with 1wt% and 2wt% polypropylene fibres.

The highest transverse strength was produced by incorporation of 2wt% glass fibres, where as lowest values were obtained from specimens containing 2wt% polypropylene fibres. Incorporation of 1wt% glass fibres and polypropylene fibres had no significant effect on the transverse strength.
