About this trial
This study aims to evaluate the clinical, radiographic, functional, and patient-reported outcomes of premolar autotransplantation used to replace anterior maxillary teeth in young patients. The study has an ambispective observational design, including a retrospective cohort (patients treated between December 2019 and December 2025) and a prospective cohort (patients enrolled until December 2028).
Participants aged 7 to 15 years who received or will receive premolar autotransplantation to replace an anterior tooth will be followed clinically and radiographically for up to 5 years. Outcomes include tooth survival, periodontal and pulpal healing, root development, complications, orthodontic interactions, restorative needs, and patient satisfaction. The study seeks to identify prognostic factors and long-term success indicators for dental autotransplantation in growing patients.
