Research Progress on Performance Parameters and Preparation Technology of Zirconia-Based Dental Materials

摘要:

氧化锆（ZrO₂）陶瓷为牙科临床使用的首选材料,其可用于修复、固定局部义齿和种植牙，然而其所使用的贴面陶瓷会在早期临床使用中出现失效，其功能完整性及耐用性有待提高。因此，对氧化锆陶瓷材料的各项性能参数及其几何学特征等方面进行了总结。阐述了热循环、制备工艺、几何形状范围内关键参数对氧化锆陶瓷材料性能的影响，为制造工艺参数改进、工艺优化等提供有益参考，从而促进氧化锆牙科材料机械性能、稳定性及功能性的改进。

Abstract:

Zirconia （ZrO₂） ceramics are the preferred materials for clinical use in dentistry. They can be used to repair， fix partial dentures and implants. However， the veneer ceramics used in them will fail in early clinical use. Its functional integrity and durability needs improvement. Therefore， the performance parameters and geometry characteristics of zirconia ceramic materials are summarized. The effects of thermal cycle， preparation process， and key parameters in the range of geometric shapes on the properties of zirconia ceramic materials are expounded， which can provide useful references for the improvement of manufacturing process parameters and process optimization， so as to promote the improvement of mechanical properties， stability and function of zirconia dental materials.
