We compared the deformation of maxillary complete dentures polymerized under conventional water bath curing and four different conditions of microwave irradiation. In the regions where there were artificial teeth, there was considerable deformation in the dentures polymerized by microwave irradiation because of large anterior/posterior shrinkage compared to small lateral shrinkage. However, there was little deformation in the dentures polymerized by conventional water bath curing. On the other hand, compared with polymerization by conventional water bath curing, there was less shrinkage and little deformation in the mucosal surface region in the dentures polymerized by three minutes of irradiation from the mucosal side, or 90 seconds of irradiation from the occlusal surface side followed by 90 seconds from the mucosal surface side. The shrinkage of all of the dentures decreased between 7 and 30 days after polymerization.
