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.
This keynote lecture will provide an overview of the CBCT-guided TAT process, emphasizing
the digital workflow and treatment outcomes. Furthermore, the presentation will explore
insights from CBCT-guided TAT that can be applied to dental root biofabrication, expanding
the potential of 3D imaging applications in paediatric dentistry.
