Abstract

In order to restore facial and oral deformities ,we need to use a strength, esthetically acceptable andbiocompatible material .Heat cure acrylic resin as we used in our study(clear acrylic) for restoring facialdeformities as it is the material that occupy these requirements. To increase the properties of acrylic resinwe added salinized poly propylene fibers and hydroxyapatite macro fillers in 120 acrylic samples dividedin control group and two experimental groups before and after artificial aging(100hr and 200hr).Hardness,impact and flexural strength are tested in this study. The results showed a none significant change in hardnessafter addition of fibers and fillers but a significant increase in hardness after artificial aging .A significantincrease in impact strength after addition, significant decrease in impact strength after artificial aging .Asignificant increase in flexural strength after addition of fibers and fillers.
