Tooth Autotransplantation of Third Molars: Achieving Success With Optimal Oral Care

Abstract Body: Tooth autotransplantation (TAT) offers a viable biological approach to tooth replacement in children and adolescents after traumatic dental injuries (TDIs), agenesis, developmental anomalies or specific orthodontic problems and in some cases failure of teeth restoration. In these cases, TAT can be utilised with predictable outcome. This lecture will focus on TAT of third molar teeth with close and open apex in cases implant placement, are limited by the ongoing dentoalveolar development or orthodontic tooth alignment is challenging unless skeletal anchorage is applied. TAT allows for periodontal healing and enables preservation of the alveolar ridge maintaining the possibility of function and growth. To enhance outcome predictability of the TAT procedure, a low-dose cone-beam computed tomographic (CBCT)-guided surgical planning and transfer technique has been developed, involving donor tooth selection and tooth replica fabrication. This lecture will focus on the digital work-flow and surgical techniques serving TAT.
