Abstract
Purpose: Acrylic resins are one of the extensively used materials in removable prosthodontics however; complete dentures are highly vulnerable to fracture after long periods of clinical use. The repair of fractured prosthesis can be accomplished using acrylic resins that are light polymerized, autopolymerized, heat polymerized or microwave polymerized. Aim: To evaluate the residual monomer content of three different repair autoploymerising resins processed by two different polymerization techniques after microwave postpolymerization treatment. Materials and Methods: The study was executed with fabrication of a metal die and sixty test specimens of three different materials. 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. Results and Conclusion: Results confirmd that their residual monomer content decreased by subjecting them to another cycle of polymerization in microwave at 550 watts for 3 minutes.
