INFLUENCE OF THICKNESS AND LOCATION ON THE RESIDUAL MONOMER CONTENT OF DENTURE BASE CURED BY 3 PROCESSING METHODS

The influence of thickness and location on the residual monomer conten t of acrylic resin plates was examined when they were processed by thr ee methods: a conventional method, fluid resin technique, and a microw ave curing method. The residual monomer contents were measured by gas liquid chromatography. The levels of residual monomer were influenced by the processing methods and thicknesses of acrylic resin specimens, but not by location within the specimens. These results suggest that d imensional accuracy and stability of acrylic resin dentures could be i nfluenced by the processing method, the thickness of the bases, and th e shape and size of the dentures.
