含钇氧化锆材料在口腔临床应用中的研究进展

Advances of yttrium-containing zirconia materials in dental clinical applications

与其他稳定类型的氧化锆陶瓷相比,含钇氧化锆陶瓷具有良好的机械和生物学性能,现已广泛应用于口腔种植、修复领域。目前临床上使用的氧化锆陶瓷种类繁多,氧化钇稳定氧化锆陶瓷(yttrium-stabilized tetragonal zirconia polycrystal,Y-TZP)机械性能突出,氧化钇部分稳定氧化锆陶瓷(yttrium-partially stabilized zirconia,Y-PSZ)则具有更优的美学性能,了解不同含钇氧化锆陶瓷的理化性质,有助于医生在临床应用中作出正确选择。本文就不同含钇氧化锆陶瓷的理化性质和临床适应证进行综述,拟为含钇氧化锆陶瓷的研究和开发应用提供参考。

Yttrium-containing zirconia ceramic(YCZC)has been widely used in field of implant and restorative dentistry.It has good mechanical and biological properties when compared with other types of zirconia ceramics.Different types of zirconia ceramics have been used in clinical application,such as Yttrium-stabilized tetragonal zirconia polycrystal(Y-TZP)with high mechanical properties,and Yttrium-partially stabilized zirconia(Y-PSZ)with high aesthetic properties.Therefore,understanding the physical and chemical properties of different YCZC can improve the clinical success of dental restorations.This article summarizes the available literature concerning the physical and chemical properties of YCZC and their clinical applications in the field of dentistry.
