Summary
This study introduces a novel 3D surgical template method for guided tooth autotransplantation. This technique ensures precise donor tooth placement and prevents bone loss, achieving successful functional and esthetic restoration.
Area of Science:
- Dentistry
- Oral Surgery
- Biomedical Engineering
Background:
- Autotransplantation of teeth is a complex procedure.
- Severe trauma can lead to avulsion of permanent teeth.
- Innovative surgical techniques are needed for successful tooth replacement.
Observation:
- A novel method for tooth autotransplantation using 3D surgical templates was developed.
- The technique modifies guided implant surgery methods for osteotomy preparation and tooth placement.
- A case report details the autotransplantation of immature premolars in an 11-year-old patient.
Findings:
- The 3D surgical template approach enabled precise, preplanned virtual transplantation.
- Guided osteotomies prevented bone loss and ensured accurate donor tooth positioning.
- One-year follow-up demonstrated vital, functional, and esthetic restoration with physiological parameters.
Implications:
- This digital workflow and 3D template system can enhance the predictability of tooth autotransplantation.
- The technique offers a minimally invasive and atraumatic surgical protocol.
- Future applications may include wider adoption for complex dental trauma cases.
