Abstract:
Objective:To study the bone-conductivity and absorbability of nano-hydroxyapatite/collagen(nHAC) composite implanted under the calvarial periosteum in rabbits.Methods:24 nHAC samples and 24 HA samples were prepaired in the shape of round disk with the diameter of 8 mm and thickness of 3 mm.nHAC samples were implanted under calvarial periosteum on the left side and HA samples on the right of 24 rabbits.The bone-conductivity and absorbability of the samples were examined by new bone height measuring and residual implant materia measuring 2,4,8 and 12 weeks after operation. Results:2,4,8 and 12 weeks after implantation new bone height(mm) in nHAC group was 0.54?0.09,0.72?0.12,1.83?0.14 and 2.63?0.07,that in HA group 0.13?0.11,0.31?0.12,1.23?0.05 and 1.75?0.14,respectively(P
