[Replantation of frozen and boiled autogenous mandible].
Mandibles devitalized by freezing or boiling after being removed from animals were reimplanted to evaluate their potentials of reunion and growth with X-ray and histological methods. The results suggested that the osteo-induction may play a partial role in the bone healing of frozen bone graft besides "creeping substitution", while the boiled one only provided a scaffold into and around which bone formation can occur. According to the rate and degree of bone graft repair, the frozen was better than the boiled which was resorbed and replaced at a slower rate.
