摘      要：AIM:To investigate the osseointegration process of titanium implant and non-vascularized iliac bone grafts.METHODS:12 mongrel were divided into 4 groups randomly.Bone grafts were resected from iliac crest and then transplanted to the other side.Animals were skilled in different time after surgery,X-ray pictures were taken,then histological observation were done.RESULTS:At 3rd week,bone grafts dissolved,resorbed or necrosis partly;At 6th week,new bone began to regenerated;At 9th week,the amount of new bone increased;At 12nd week,bone interface around implant formed,without soft tissue interrupt.CONCLUSION:Osseointegration can formed between non-vascularized iliac bone grafts and titanium implant.
