RESUMO
INTRODUCTION: Dental autotransplantation is a surgical procedure that involves the implantation of a tooth with incomplete root development to replace an injured or missing tooth. An initial surgery was performed to attempt orthodontic traction without success after 6 months. TECHNIQUE: Preoperative assessment included mandibular cone beam computed tomography to visualise two canines. The double autotransplantation technique was performed under general anaesthesia using three-dimensional resin-printed dental replicas. The extra-alveolar time for each tooth was reportedly <1 min, and pulp sensibility was observed 3 months later. CONCLUSION: In the digital era, dental autotransplantation has become an essential part of orthodontic-surgical treatment in children and adolescents with dental agenesis or non-preservable teeth. The use of three-dimensional dental replicas printed from radiological data offers a reliable, reproducible, and valid therapeutic solution with an advantageous benefit/risk balance.
