![]() The overall 3-year survival rate of autotransplanted mandibular molars in this study is 75% with two cases of failure of treatment (25%) occurring 6 months following the procedure. Patients were within 15–17 years of age, with a mean age of 16.0+0.93 years. Results: Eight cases of molar to molar autotransplanting were done in seven patients. Patients were recruited in a period of 2 years and had follow-up visits up to 3 years post-transplantation. Methods: This preliminary study was conducted in patients diagnosed with grossly carious and non-restorable molar teeth, and subsequently managed by molar to molar autotransplanting. Although extraction and replacement with osseointegrated implants may be acceptable in adult patients, these treatment options are not ideal in adolescents. The patient’s aesthetic satisfaction was not considered in the studies.īackground: The first permanent molars are frequently affected by caries partly because they are the first teeth to erupt in the oral cavity and partly because of their susceptibility by virtue of their morphological and functional characteristics. Bone and periodontal tissue do not appear to be affected by orthodontics. ![]() In teeth, there was an increase in root resorption influenced by orthodontics, but without impacting on the general clinical result in the long term. There was a sufficient body of evidence that justified autotransplantation in patients who needed orthodontic movement. The quality of the set of evidence was considered medium due to the presence of different methodological problems, risk of bias, and significant heterogeneity in the evaluated studies. The selected studies included 715 patients and 934 autotransplanted teeth among which there were premolars, molars, and anterior teeth evaluated in the long term, indicating that orthodontics associated with autotransplantation indicated a result that was generally clinically acceptable. The results showed 10 controlled clinical trials, and no randomized clinical trials were found. Risk of bias was evaluated using the methodological index for nonrandomized studies-MINORS. For outcomes, the results with reference to teeth, alveolar bone, periodontal tissues, and esthetic satisfaction were considered. For triage of articles, indications, surgical planning, orthodontic movement, risk factors for treatment, and long-term follow-ups were considered. A bibliographic search was conducted without limitations on year of publication or language in the databases of PubMed, Web of Science, Scopus, Medline Complete, Cochrane, Clinical Trials, and Trials Central. This systematic review was focused on evaluating tooth autotransplantation, considering its impacts on the teeth, bone, soft tissues, and aesthetics in orthodontic patients. The success ratio of premolar transplants was 100%. Eleven of 22 premolar transplants had a root canal treatment (RCT), four of which had RCT within 2 years after the operation. Two transplant patients, one with a medical history of histiocytosis and the other with a history of osteomyelitis of the maxilla without a recipient socket, were also excluded from this study. The success ratio of all 28 transplants was 100%, although four transplants shorter than a 4-year period of observation were omitted. All recipients maintained the retained primary tooth with a socket. Recipient sites were: ten for missing maxillary canines, nine for maxillary centrals and laterals, eight for lower second premolar, and five for other missing premolar sites. All transplants were conducted in a one-phase operation by one operator (Dr Inoue). Three sets of dental radiographs were taken by one dental assistant using a custom holder at: preoperation (T0), 2 year postoperation (T1), and retention (T2) (4- to 14-year follow-up observation) stages. At a routine 3-month appointment, patients underwent a dental radiograph and a chair-side observation for periodontal problems. In the present study, 28 premolar transplants from 24 orthodontic patients were associated with orthodontic treatment. To test the null hypothesis that premolar autotransplantation is not successful for orthodontic patients.
