Autogenous free tooth transplantation by the two-stage operation technique. An analysis of treatment factors.

Teeth were autogenously transplanted by the 2-stage technique in adult patients and examined up to 5 years after surgery for the prevalence of, and correlation between, tooth graft loss, root resorption, ankylosis, periodontal attachment loss, tooth mobility, and pain. The influence on the dependent variables of independent variables related to the patient, the donor tooth, the recipient site, and the transplantation procedure was examined. Pain was correlated to transplanted teeth, later extracted, and teeth with periodontal attachment loss. The expected correlation of root resorption to periodontal attachment loss was not verified owing to incomplete follow-up. The older the patient was, the less root resorption was found. Variables indicative of infection of the recipient bed and of traumatic injuries to the donor tooth at the transplantation were found to be detrimental to the tooth transplant.
