There are multiple prognostic factors that may influence the outcomes of premolar auto\u2010transplantation, but there is limited evidence from human studies. The aim of this study was to report the outcomes of auto\u2010transplanted premolars in the anterior maxilla following traumatic dental injuries (TDIs) and to identify their prognostic factors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>The clinical records of patients who had premolars transplanted in the anterior maxilla following TDI, with appropriate radiographs and a minimal of 1\u2010year follow\u2010up, were reviewed retrospectively. A specific data extraction form was developed, tested and used to collect information for the prognostic factors and outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The cohort included 120 patients with 144 auto\u2010transplanted premolars. The mean age was 12.2\u2009years (\u00b12.0), and the mean observation period was 3.7\u2009years (\u00b11.8). The success rate was 80%, and the survival rate was 93%. Unfavourable outcomes included external replacement resorption in 12.5%, uncontrolled external inflammatory resorption in 2.7%, and both resorption types in 4.9% of teeth. Periodontal healing was significantly associated with donor tooth root maturity, graft handling at the time of surgery including ease of donor tooth extraction and placement at the recipient sites, recipient site alveolar bone status, and post\u2010operative transplant mobility. Seventy\u2010four teeth (53.4%) were immature at the time of transplantation where pulp revascularisation was anticipated, and 52 (70%) of those had radiographic and clinical signs of pulp healing. Pulp healing was significantly related to donor tooth eruption stage, ease of extraction of donor tooth, and ease of placement in the recipient site.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Good outcomes were observed for premolar teeth auto\u2010transplanted in the anterior maxilla.
