Comprehensive Guide to Tooth Autotransplantation in Children: From a to Z Including the Role of Sustained Oral Hygiene

Abstract Body: Tooth autotransplantation (TAT) is a valuable biological solution for tooth replacement in children and adolescents affected by traumatic dental injuries (TDIs), agenesis, developmental anomalies, or specific orthodontic issues. With a relatively high prevalence of 15.2%, TDIs predominantly impact children. Conventional treatment options, such as implant placement, are constrained by ongoing dentoalveolar development, while orthodontic tooth alignment proves challenging without skeletal anchorage. TAT facilitates periodontal healing, preserves the alveolar ridge, and maintains function and growth potential.
To improve TAT outcome predictability, our research group at the KU/UZ Leuven has developed a low-dose cone-beam computed tomographic (CBCT)-guided surgical planning and transfer technique, encompassing donor tooth selection and tooth replica fabrication (3D printing). This lecture will provide an overview of the CBCT-guided TAT process, emphasizing the digital workflow and treatment outcomes.
