Objective:To study the feasibility of applying nanometer ceramics artificial bone in clinical repair of bone defects.Methods:The animal models of bone defect was made on the unilateral radius of 45 New Zealand white rabbits,which were divded into experimental group(repair with nanometer ceramics artificial bone),control group(repair with ceramics artificial bone)and blank group(unrepaired) randomly.The reconstructive effect in each group was evaluated by gross observation,alkaline phosphatase(ALP) detection of blood serum histopathological observation,X-ray examination and SEM detection at 4th,8th and 12th weeks postoperatively.32 cases bony defects were rpaired with the nanometer ceramics artificial bone.
