摘　　要：氧化锆陶瓷兼具优异的力学性能和美学性能,在口腔医学领域应用广泛。然而,临床常用的四方相氧化锆陶瓷在口腔环境中可发生低温老化,导致修复体表面粗糙度增加、微裂纹产生、力学性能下降等。氧化锆陶瓷低温老化受晶体大小、应力、稳定剂含量和类型、表面处理、烧结条件等因素影响,本文就口腔修复学领域氧化锆陶瓷低温老化的研究进展进行综述,以期为氧化锆陶瓷的基础研究和临床应用提供参考。Zirconia is widely used in the field of dentistry because of its superior mechanical and esthetic characteristics.However,the tetragonal zirconia polycrystal restorations commonly used in clinics will degrade at low temperatures in the oral environment,resulting in increased surface roughness,microcracks,and decreased mechanical properties.Low-temperature degradation of zirconia can be affected by grain size,stress,stabilizer content and type,surface treatment,sintering conditions,and other factors.Through a literature review and analysis,this review summarizes the research progress on the low-temperature degradation of zirconia in prosthetic dentistry to provide references for the improvement of zirconia in clinical and research applications.
