摘要:
The intent of this project was to evaluate any changes in the flexure strength of magnesia‐partially‐stabilized zirconia when aged in distilled water for time periods of 6, 12, and 18 mos. The aging conditions were autoclaved specimens in air (AA) or distilled water (AW) and nonautoclaved specimens in distilled water (NW) at stressing rates of 10.0, 1.0, or 0.1 mm/min. The statistical analysis showed no significant difference between the aging times. The aging‐time data were then pooled and a statistical analysis run between the different aging conditions (AA, AW, and NW) and stressing rates. The specimens tested in air were significantly stronger than those tested in water autoclaved or nonautoclaved. For the pooled data, all stressing rates were statistically significant from each
