ABSTRACT
[Objective] To evaluate the histocompatibility of nano hydroxyapatite-zirconia composite bioceramic.[Methods]According to the standard of ISO 10993-1,cytotoxicity experiment,acute toxicity test,hemolysis test and in vivo implantation(90 days)test were conducted to evaluate the histocompatibility of nano hydroxyapatite-zirconia composite bioceramic.[Results]The score of cytotoxicity experiment was lower than grade I,and there was no significant inhibition of cell growth,no acute toxic reaction or hemolytic reaction.And the in vivo implantation met the requirements of the biological evaluation of implant materials.[Conclusion]Nano hydroxyzpatie-zirconia composite bioceramic showed a good histocompatibility.It has a broad prospect as a biomaterial scaffold in the bone tissue engineering.
