Autotransplantation of teeth with incomplete root formation: systematic review and meta-analysis

Objectives To determine the survival of intentional autotransplantation of developing teeth. Material and methods An electronic search was carried out in the MEDLINE database, Web of Science, and Cochrane Library. The criteria used are the ones described in the PRISMA Declaration. The following MeSH terms were used: (tooth [MeSH Terms] OR tooth [All Fields]) AND (transplantation, autologous [MeSH Terms] OR (transplantation [All Fields] AND autologous [All Fields]) OR autologous transplantation [All Fields] OR autotransplantation [All Fields]) AND (humans [MeSH Terms]. Randomised clinical trials and prospective and retrospective clinical studies were included. Results The meta-analytic study of overall survival included a total of 14 studies, yielding an overall survival rate of 97.9%. In studies with 1-year follow-ups, survival was 98%. The resulting 2-year follow-up rate was 97%, while the 5- and 10-year survival rates were 95.9% and 96.9%, respectively. Conclusions The autotransplantation technique performed in a single-phase and on teeth that have not completed their development is a predictable technique, with a described survival rate at a 2-year follow-up of more than 97%.

Automated summary

This study investigated the survival of intentionally autotransplanted developing teeth and found a survival rate of over 97% at a 2-year follow-up.
