氧化锆全瓷修复体抗折强度的影响因素

The factors influencing the flexural strength of zirconia ceramic restorations

氧化锆材料在口腔修复中具有广阔的应用前景,与CAD/CAM技术结合制作的修复体,应用日趋广泛。本文综合了目前常用的氧化锆全瓷修复体的材料特性、抗折性能的影响因素,以及评价其抗折性能的相关指标和方法,为氧化锆全瓷修复的临床应用提供参考。

Zirconia material has a very broad application prospect in prosthodontics,and restorations made of zirconia through CAD/CAM technology have been applied widely in recent years.In this paper we summarized the features of zirconia material which used for all ceramic restorations and the factors which affected its flexural property.We also sated the relevant indicators and methods used for evaluation of flexural property of zirconia material in order to lay a basis for its clinical use.
