In order to restore facial and oral deformities ,we need to use a strength, esthetically acceptable and
biocompatible material .Heat cure acrylic resin as we used in our study(clear acrylic) for restoring facial
deformities as it is the material that occupy these requirements. To increase the properties of acrylic resin
we added salinized poly propylene fibers and hydroxyapatite macro fillers in 120 acrylic samples divided
in 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 hardness
after addition of fibers and fillers but a significant increase in hardness after artificial aging .A significant
increase in impact strength after addition, significant decrease in impact strength after artificial aging .A
significant increase in flexural strength after addition of fibers and fillers.
