饰面瓷崩瓷是影响氧化锆全瓷修复体临床成功率的重要因素.饰面瓷崩裂与饰面瓷材料强度、残余应力的产生及界面粘接情况有重要联系,但目前对饰面瓷-锆瓷复合结构的力学性能研究尚缺乏标准试验,其结果受到试样的几何形状、应力加载的方向、大小、频率以及口内环境模拟等因素的影响,不同试验结果之间的可比性较差,其研究结果也不能完全反映临床现象.明确可以用于双层结构真实强度及韧性的测试方法及评价指标、进一步研究各影响因素对强度和韧性的作用等是未来亟待研究的问题.本文就目前对氧化锆全瓷修复体崩瓷原因的相关研究进展作一综述.

Porcelain chipping-off, supposed to be affected by the mechanical strength of porcelain material, residual stress and the interface bonding strength, is well documented as a reason for veneered zirconia crown failure. However, results from different tests were incomparable because the testing methods varied in respecting to specimen dimension, direction and frequency of loads, and simulation of intraoral environment. The standardized methods and evaluation index applied in testing the real strength and toughness of double-layer structure are the goals to be achieved in future, and the factors related to the strength and toughness should also be evaluated. In the current review, reported flaws leading to porcelain chipping-off were summarized.
