“…Thus, in younger patients, autotransplantation is indicated and is often carried out in conjunction with orthodontic treatment. 6,13,14,20 21 also achieved favorable results: 96% of immature premolars and 82% of mature premolars transplanted to the maxillary incisor region were successful 4 years after surgery. In a study by Czochrowska et al, 22 it was concluded that in adolescents, transplantation of premolars may be recommended to replace missing maxillary incisors.…”

Objective: To evaluate the success rate of autotransplantation of teeth in consecutive patients and to analyze factors affecting the outcome. Materials and Methods: The subjects consisted of 215 consecutive patients (101 women and 114 men; aged 9.1-56.4 years, median age 15.2 years [P 10 5 11.4, P 90 5 19.7]) who had undergone transplantation of a total of 269 teeth, all by the same surgeon. In patients with multiple transplants, only the first transplant was included, to ensure that all transplanted teeth were independent units. The transplants were recorded as unsuccessful if the tooth had been extracted or was surviving but with root resorption or ankylosis. The interval between transplantation and final follow-up was a median 4.8 years (P 10 5 2.0, P 90 5 5.5) for successful transplants and a median of 2.4 years (P 10 5 0.4, P 90 5 7.7) for unsuccessful transplants. Results: One-hundred seventy-five (81%) of the transplantations were recorded as successful and 40 (19%) as unsuccessful. Twenty-five teeth had been extracted and 15 had survived but did not fulfill the criteria for success. Conclusions: The success rate of 215 consecutively transplanted teeth was 81%. The highest success rate was for transplantation of premolars to the maxillary incisor region (100%).Complications at surgery such as difficult extraction, deviant root anatomy, or damaged root periodontium affected the outcome. During growth, a successful transplant preserves alveolar bone. (Angle Orthod. 2010;80:446-451.)

“…The success rate is reported to be higher than 80% when the root length of the autotransplanted premolar is 50% to 75% of the normal root length at the time of the surgery. 2,4,6,10,12,13 Lagerströ m and Kristerson 14 reported maintenance of at least 70% of the final root length to be a criterion for successful outcome.…”

“…Furthermore, studies on orthodontically moved transplanted premolars have revealed an additional decrease in final root length in relation to transplants that were not treated orthodontically [18,28]. This can be attributed to the known correlation between orthodontic tooth movement and root resorption [19,31].…”

“…Bei vier Patienten wurden jeweils zwei Transplantationen durchgeführt. Die 21 weiblichen und zehn männlichen Patienten hatten zum Zeitpunkt der Transplantation ein Durchschnittsalter von 17,4 (16,(1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)8) bzw. 18,5 (16,5-20,0) Jahren.…”

“…Orthodontic treatment must be carried out before any postsurgical complications occur in the tooth, because of the difficulties in treating such conditions in the presence of excessive root resorption or ankylosis [7][8][9]. This paper describes fourteen cases of surgical repositioning or transplantation of a tooth followed by orthodontic treatment, paying particular attention to timing in relation to ankylosis or other postoperative complications.…”
