Allogeneic tooth transplantation with an observation time of 16 years. Clinical report of 32 cases.

Allotransplantation (grafts between dissimilar members of same species) of teeth has been used for many centuries. The grafts are rejected after various postoperative periods because of histoincompatibility between donor and recipient. However, cases with a comparatively long survival time are seen. Suppression of the host's immune mechanisms is for the present time fraught with dangerous side effects, and is for this reason not applicable in cases of tooth transplantation. Another possibility is to genetically match the donor and recipient. The normal lymphocyte transfer (NLT) test was the first method used in this respect. The author attempted this method and reports the results of 32 allotransplanted teeth after an observation time of 16 years.
