This study investigated the effect of different microwave curing cycles on the changes in occlusal vertical dimension of complete dentures. Four test groups with 12 maxillary dentures each were evaluated. Groups 1, 2 and 3 were polymerized with different cycles by microwave radiation and Group 4 was the control and cured by water bath. The average pin opening for all groups was less than 0.5 mm. There was no significant difference between the groups polymerized by the microwave method and the control group. However, analyses of the vertical dimension changes showed statistically significant differences between groups 2 (0.276 +/- 0.141 mm) and 3 (0.496 +/- 0.220 mm).
本研究调查了不同微波固化周期对全口义齿咬合垂直距离变化的影响。对四个试验组进行了评估，每组有12副上颌义齿。第1组、第2组和第3组通过微波辐射以不同周期进行聚合，第4组为对照组，通过水浴固化。所有组的平均销孔开口小于0.5毫米。微波法聚合的组与对照组之间无显著差异。然而，垂直距离变化分析显示，第2组（0.276±0.141毫米）和第3组（0.496±0.220毫米）之间存在统计学显著差异。
