The effect of continuous poly (methyl methacrylate) fibres on some properties of acrylic resin denture base material.
This study investigated the effect of continuous poly (methyl methacrylate) fibres on the transverse strength and impact strength of poly (methyl methacrylate) denture base resin. The fibres were added in three arrangements, a single unidirectional (longitudinal in the length of the specimen) layer, two longitudinal layers and in cross ply form (a combination of an inferior longitudinal layer and a superior transverse layer). The results indicated that the transverse bend and impact strengths of poly (methyl methacrylate) denture base resin, were not significantly improved by the addition of poly (methyl methacrylate) fibres.
