Background: Polymethylmethacrylate (PMMA) has been the most popular material for the construction of denture bases since 1937. This is largely due to its favourable although not ideal characteristics. Aims of the study: To study the structural characterisation using Fourier transform infrared (FTIR) of adding aluminium oxide (Al2O3) and silver nanofillers on heat cure acrylic powder treated with microwave radiation and microwave-treated PMMA powder ground by micronizer. Materials and Methods: PMMA powder was treated with microwave radiation at a power level of 360 watt for ¾ h. The obtained PMMA powder was then grinded using a domestic blender group (V). The next step is particle size reduction of the microwave-treated PMMA powder using micronizer group (M). Two concentrations of Al2O3and Ag nanoparticles (NPs) were added separately into untreated PMMA powder group (P) and microwave-treated PMMA powder group (V and M) compared with the control group. The structural characterisations of all experimental groups are determined by FTIR. The samples were divided into 15 groups, one sample for each group. Results: The FTIR analysis has confirmed that the structural behaviour of both microwave and micronizer groups showed that there were no changes in the regions of the band locations for C=C and C=O when compared with the control one. The infrared spectra of all acrylic groups with (Al2O3and Ag) NPs additives showed all of the unique peaks attributed to the PMMA. These bands appeared in the same regions of the acrylic except the carbon double bond carbon (C=C) were absent in the infrared spectrometer chart. Conclusion: The FTIR test charts provide strong evidence that there are no chemical changes in all experimental groups. Except for the C=C band from the methacrylate group did not appear in samples containing NPs, which in turn indicates that the residual monomer of these groups is remarkably decreased.
