Abstract
Decalcified bone implants induce new bone formation. In this experiment, the autogenous bone implant of canine mandible was treated by HCl under ultrasonic exposure for rapid decalcification. The aim of this study was to investigate the osteoinduction property of this rapidly decalcified bone reimplanted to the original site. The decalcified bone implant exhibited a similar degree of new formation to that of the fresh bone graft which was not subjected to decalcification. The results demonstrate that the combinational use of HCl and ultrasonic exposure for rapid decalcification treatment preserves the regenerative capacity of bone to be implanted.
