Survival probability of dental autotransplantation of 366 teeth over 34 years within a hospital setting in the United Kingdom

Abstract

Summary Introduction The purpose of this retrospective study was to evaluate 34 years’ experience of autotransplantation of teeth during orthodontic treatment. Methodology Treatment was completed at Queen Mary’s Hospital, Sidcup, Kent, UK, during the period 1969–2003. A total of 366 teeth were transplanted in 314 patients. Results Canines totalled 78 per cent of all autotransplanted teeth; mean age of patient was 19.4 years. Survival probability for the first 5 years post-autotransplantation was 95 per cent, 94 per cent for the subsequent 5 years, and 88 per cent after 15 years. The maximum observation period was 34 years, the median was 2.0 years, and the mean was 3.51 (standard deviation = 3.68) years. Of the observed teeth, 10 failed and these were lost due to unsuccessful periodontal ligament regeneration and persistent mobility grade III (or greater). Apical pathology was observed in 16 per cent of all autotransplanted teeth. In 79 per cent of this subgroup, apical pathology was evident in the first 3 years post-operatively. Seventy per cent of all external resorption also occurred within the first 3 years. Internal resorption was rare but its occurrence was mostly observed between the second and sixth year post-transplantation. A minority of autotransplanted teeth [14 per cent (n = 51)] needed root canal therapy, and this was completed within the first 6 months post-transplantation. Conclusions Autotransplantation can be a justified procedure with good survival probability. It can be considered an alternative to other treatments, such as prosthodontic replacement of teeth.

Surgical Management of Multiple Dental Anomalies in an Adolescent: A Case Report

“…By keeping the natural teeth versus any kind of prosthetic replacement, there was potential for induction of further alveolar bone growth and maintenance of a normal periodontal ligament to support proprioceptive function, along with maintenance of the interdental papillae, giving a more optimal aesthetic result [8]. Furthermore, as autotransplanted teeth have the potential to erupt alongside neighbouring teeth during continued facial growth of the patient, this is also a good option in younger patients who are still growing [13]. Autotransplantation has been a useful technique that has been performed with good outcomes [13].…”

Other studies have concluded that fully developed teeth require root canal treatment following autotransplantation, due to the high possibility of pulpal necrosis [8].…”

Clinical aspects of tooth autotransplantation and post-endodontic restoration of autrotransplanted tooth: case-based literature review

“…In the case of an open apex, an immediate root canal treatment should not be performed, so that a follow-up can be carried out and the root may nish forming without showing signs or symptoms of infection. Root canal treatment is needed only when there are radiological signs of resorption or periapical pathology [15]. If the root canal treatment is necessary, it should be performed prior to transplantation or 15 days after.…”
