以牙科复合树脂现存缺点为背景，对纳米技术对复合树脂的改良情况进行了研究，着重讨论了纳米材料对复合树脂的聚合收缩、抗菌性能和机械性能改良的一系列问题。研究结果表明,使用纳米技术和材料可以很好地改进复合树脂多方面的性能，同时对复合树脂的发展方向和研究前景进行了展望。

In this paper, nanotechnology for the improvement of dental composite resins has been reviewed in the background of the existing shortcomings, focusing on the improvement for polymerization shrinkage, anti-bacterial properties and mechanical properties of composite resins. The results show that the use of nanotechnology and nano materials can be an effective method to improve the performance of dental composite resins in a various ways. At last, the paper also gives a future perspective of dental composite resins.
