Abstract：Objective:To investigate the nano-silver containing hydroxyapatite coated ceramic bracket's anti-microbial properties. Methods:Microplasm a spraying was chose to deposite the nano-silver containing hydroxyapatite coating, and the Agion concentration was exam ined by IC P-AESat 1、3、7、1 4、21days and the anti-bacterial effect were test by the coating film method.Results:Agion concentration increased with time and the release speed decreased with time, the structure became stable after 14 day, the anti-bacterial ratio was 99.9% . Conclusion: The nano-silver containing hydroxyapatite coating was proved to be an effective system for delivering silver ions and exhibit excellent anti-bacterial ability against streptococcus mutans. The coating could reduce the decalcification of enamel during the orthodontic treatment.
