Study the FTIR of Hydroxyapatite Additive to Heat Cured Acrylic Resin

Abstract

To evaluate the FTIR of Hydroxyapatite additives 2 %, and 5 % of dry (HAP) prepared from egg shells to the polymer. Materials and Methods: Thirty six specimens of heat cured acrylic resin and other specimens of heat cured acrylic resin with 2 % and or 5 % prepared then immersed in distilled water for 48 hours then dried for 24 hours then scratched with sharp knife and measured by FTIR spectra. Results: The result showed when adding 2% &/or 5% hydroxy apatite to heat cured acrylic resin denture base material resulting a homogenous mixture, without chemical reaction in between and without changes of acrylic resin properties. Conclusion: they can be used together in patients with bone hydroxy apatite deficiency
