口腔修复中氧化锆陶瓷低温老化的评估及解决策略
Zirconia ceramics in dental restoration:evaluation and solutions for low-temperature degradation
摘要
Abstract
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.关键词
