Tooth autotransplantation clinical success – a retrospective study with follow-up period varying from 8 months to 8 years

Research output: Contribution to conferenceAbstractpeer-review


The aim of study was to evaluate the long term outcome of autotransplanted teeth (AT) in the frontal region. This was a retrospective cohort study. The sample consisted from 37 patients with 38 autotransplanted teeth who were treated at the Library (Riga Stradins University) between 2012-2019. In the final sample were included 29 teeth. Eight patients were excluded because the transplanted teeth were in the posterior region. The follow up period varied from 8 months to 8 years, with the mean of 3.1 years. The following baseline information was recorded from the patients' medical files: gender, age at transplantation, indication for transplantation, donor tooth and the status of the recipient site, the root formation stage, Age at transplantation was from 8.9 to 12.7 years. All donor teeth were premolars. During recall visit a periapical x-ray was taken and clinical assessment of pink esthetic score (PES) and white esthetic score (WES) were used to evaluate the clinical outcome. As the success criteria were set: no inflammation, normal periodontal tissues, root/ crown ratio > 1. A score “tentative” was given, if one of criteria above was not fulfilled, and failure was recorded, if tooth was lost Only 9 of 29 transplated teeth were reconstructed using composite material. The mean WES score was 6.7. Soft tissue evaluation using PES score showed mean score of 6.5, but 10 patients still had on going orthodontic treatment. Sixteen teeth were classified as success, 13 teeth’s prognosis was classified as tentative. None of autotransplanted teeth was lost during this follow- up period. Tooth autotransplantation can be treatment of choice for replacement of missing anterior teeth. The protocol of this procedure needs to be improved because of rather high percentage of tentative cases.
