全瓷修复材料以良好的美学特性、生物相容性和机械性能在临床上得到了广泛的应用,但全瓷冠桥在复杂的口腔环境下常出现老化现象,致使全瓷材料的颜色及机械性能产生变化。研究全瓷材料的老化现象及其规律可为临床全瓷冠桥的可靠性和耐久性评价及其改进提供有效的理论依据。本文就全瓷材料的老化现象对其颜色和机械性能的影响及影响老化的因素作一综述和评价。 All-ceramic restoration materials with good aesthetic properties, biocompatibility and mechanical properties have been widely used in clinical practice, but all-ceramic crown bridge in the complex oral environment often appear aging phenomenon, resulting in the color of all-ceramic materials and machinery Performance changes. Studying the aging phenomenon and its regularity of all-ceramic materials can provide an effective theoretical basis for the evaluation and improvement of the reliability and durability of all-ceramic crowns. In this paper, the aging phenomenon of all-ceramic materials on its color and mechanical properties and the impact of aging factors are reviewed and evaluated.
