摘　　要：具有特殊相变增韧能力的氧化锆陶瓷凭借其优异的机械性能、生物相容性和化学稳定性在口腔修复中得到了广泛的应用,但其相变增韧能力也容易导致临床应用中发生低温老化现象,影响长期使用寿命。低温老化不仅严重影响材料机械性能,还会通过改变半透明度、颜色对美观性造成不利影响。本文深入探讨了影响低温老化的关键因素,包括稳定剂种类和含量、晶粒尺寸及残余应力,并就氧化锆陶瓷低温老化的评估及减缓策略作一综述,为牙科氧化锆的发展提供新视角。Zirconia ceramics,which have unique phase transformation toughening capabilities,have garnered wide‐spread attention for their excellent mechanical properties,biocompatibility,chemical stability,and optical characteristics.However,their phase transformation toughening ability is a limitation in clinical applications,affecting the potential for long-term use due to low-temperature degradation(LTD).LTD not only severely affects the mechanical properties of the material but also has adverse effects on aesthetics by changing the translucency and color.This article delves into the key factors influencing LTD,including dopant types as well as content,grain size,and residual stress.Moreover,this article re‐views strategies for evaluating and mitigating LTD in zirconia ceramics,providing new perspectives for the development of dental zirconia.
