Stress relaxation of four temporary restoratives was studied. In the vicinity of ambient mouth temperature, the relaxation characteristics of an unmodified zinc oxide-eugenol cement were more favorable than those of IRM and Cavit. The plastic behavior of gutta-percha temporary stopping precluded assessment of its relaxation at temperatures in excess of 22 degrees C.
研究了四种临时修复材料的应力松弛情况。在口腔环境温度附近，未改性的氧化锌丁香酚水门汀的松弛特性比IRM和Cavit的更有利。超过22摄氏度时，牙胶暂封材料的塑性行为使得无法评估其松弛情况。
