Study the FTIR of Hydroxyapatite Additive to Heat Cured Acrylic Resin

Abstract

Aims: 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.

Dynamics of different ion release from denture-base acrylic resins and their mechanical properties after the addition of bioactive materials

“… Hassan et al (2014) tried to modify acrylic resins with the addition of HA in concentrations of 2% and 5% and measured their infrared spectrum. They observed no chemical reaction between polymers and HA and indicated that the material can be released for a certain time and act as an alternative to bone cement used for patients with HA deficiency.…”

The effect of addition of hydroxyapatite from skipjack tuna (katsuwonus pelamis) fish bone flour to the transverse, impact, and tensile strength of heat cured acrylic resin

“…Although the percentages of 2% and 5% of hydroxyapatite added to acrylic resins produce a homogeneous mixture and without chemical reactions, monomers that are not bound to polymers will produce weaker bonds or become residual monomers and affect the mechanical properties of acrylic resins. 13 The tensile strength of acrylic is influenced by the temperature of the polymerization. Changes in high ambient temperature cause shrinkage of acrylic resin particles.…”

“…In contrast, the characteristic FT-IR peaks located at around 1410 and 1018 cm − 1 are correspond to a symmetric stretching of ionized COO − and P-O, respectively (Ehrlich et al, 2006). The residual peaks ranging from 900 to 400 cm − 1 should due to the different vibration modes of O-P-O bonds (Hassan et al, 2014;Koutsopoulos, 2002).…”
