The test was carried out using Fourier transform infrared spectroscopy (FTIR) Machine (Impact 400D-Nicolet Offenbach, Germany) [Figure 3].

FTIR technique has been used for qualitative and quantitative analysis of residual monomer during polymerization of polymethyl methacrylate.

The pressure pot was filled with water at temperature 40°C and internal pressure was regulated to 2.5 bars.

The specimens were retrieved from flasks followed by finishing and polishing.

They are also being used in other areas like making denture bases, certain maxillofacial prosthesis, relining of dentures, provisional restoration, and so on.

Hence, superior physical and mechanical properties are expected from autopolymerizing resins.

All the submitted samples were first cut into small pieces with the dimensions of 0.2 × 0.2 × 0.2 cm.

The cut piece was then mounted on the FTIR (Fourier Transform Infrared) crystal [Figure 4].

Materials and Methods: The study was executed with fabrication of a metal die and sixty test specimens of three different materials.

There was statistically significant difference in the residual monomer content, before and after microwave postpolymerization treatment of all the three materials whether polymerized under normal conditions or in a pressure pot (P Residual monomer content present in autopolymerized acrylic resins has restricted its usage as a choice of material for final prosthesis.

Despite this, its properties like less time consumption for acralysation autopolymerizing resins are widely being used for repairing dentures.

The specimens were cured with conventional method and using pressure pot.

After this the specimens were tested for residual monomer content using Fourier transform infrared spectroscopy.
