Wisdom tooth transplants offer youth the possibility of biologically fixed tooth replacement in cases of premolar agenesis or premature loss of a molar. In the present study, 57 transplants of third molars were reviewed and evaluated retrospectively on preoperative findings (root growth stages, extraction sites, indication for transplantation), on postoperative clinical findings (local gingivitis, periodontal probing values, tooth mobility, percussion sound and percussion pain) and on radiological findings (tertiary build-up of dentin, osseous periradicular conditions, progress of root growth). Only the transplants which healed with a vital pulp and in a periodontally healthy state were considered successful. Upper and lower wisdom teeth having 50% to 75% root growth progression were transplanted. The postoperative follow-up observation period averaged 26.4 months. The success of a wisdom tooth transplantation was not influenced by the root growth stage (p = 1), the extraction location of wisdom teeth (p = 0.45), or the feasibility for a transplantation (p = 0.56). Three teeth showed pulpal necrosis with apical periodontitis and were counted as failures. The success rate was rather high with 54 out of 57 transplants (94.7%), therefore wisdom tooth transplantations, with careful selection of a suitable graft and its gentle removal, can be described as a good predictable treatment.
