摘要

商业氧化锆陶瓷老化的温度依赖性在牙种植体的应用中至关重要。研究了氧化锆牙科陶瓷的结构、力学性能与长时间人体温度敏感性的关系。将商业样品置于ISO标准的夸大低温降解(LTD)和老化温度的四分之三，以观察其对氧化锆基陶瓷LTD的影响。结果表明，当温度低于氧化锆的标准LTD温度134℃时，LTD对材料的影响可以忽略不计。

Temperature dependence in ageing process in commercial zirconia dental ceramics

ABSTRACT The temperature dependence of ageing in the commercial zirconia ceramic is crucial in the applications of dental implants. This study investigated the relationship between structure and mechanical properties of the zirconia dental ceramics and their susceptibility to human body temperature in a prolonged time. Commercial samples were put into exaggerated low-temperature degradation (LTD) as per ISO standard and three-quarters of its ageing temperature to see its effect on LTD in zirconia-based ceramics. The results reveal a negligible effect of LTD on the material at a temperature lower than 134°C, which is the standard LTD temperature for zirconia.
