A comparison of the dimensional accuracy of microwave and conventionally polymerized denture base materials.
This study compares the dimensional changes of microwave and conventionally polymerized denture bases and also establishes the degree of monomer conversion using gas-liquid chromatography. Dimensional changes of three denture base materials were assessed using an optical comparator and the results showed no significant differences between the materials employed or the curing method used.  Efficient monomer conversion was demonstrated with levels of residual monomer of less than 1% for all materials.
