[An experimental study on transplantation of frozen autogenous tooth-mandible compound].
OBJECTIVE
To study the feasibility of reserving the teeth in the transplantation of frozen autogenous mandible.


METHODS
Forty adult Wistar rats were used for these operations of transplantation of frozen autogenous tooth-mandible compound (ATMC) and fresh ATMC. Then the healing process after transplantation of frozen ATMC and fresh ATMC was compared by clinical, radiographical, histological and microangiographical observation.


RESULTS
There were no significant differences between the healing process of frozen ATMC and that of fresh ATMC, and the fibres of regenerated periodontal membrane which maintained the dental root in normal position could be imbedded in the newly formed cementum.


CONCLUSIONS
It is feasible to transplant the frozen ATMC for reconstructing the mandible and improving its function in clinic.
