纳米填料改性玻璃离子水门汀的研究进展

Development of Glass Ionomer Cement Modified by Nano-fillers

玻璃离子水门汀(GIC)是一种广泛用于口腔临床的修复材料,但存在抑菌性和机械性能不足的问题,治疗后牙体继发龋感染和修复体破损时有发生,进而造成治疗失败。随着材料技术的发展,纳米粒子其因卓越的理化性能而被逐渐应用于GIC材料的改性研究中。但目前的研究仍存在一定的缺陷,难以实现临床应用。分析不同改性设计的优缺点,将有助于找到提升GIC性能的更优方案。因此,本文就纳米填料改性玻璃离子水门汀的研究成果作一总结,以期为拓宽GIC在口腔医学领域的应用提供思路。

Glass ionomer cement(GIC)has been universally used for tooth restoration.However,its insufficient antibacterial and mechanical properties usually lead to damage and secondary caries,resulting in the treatment failure.With the development of material technology,nano particle came into existence and has been utilized in the modification of GIC due to its excellent properties.However,current studies are still imperfect.Here,the researches on GIC modified by different nano-fillers are systematically reviewed.
