Primary tooth autotransplantation is a successful technique for replacing missing teeth in children, supporting bone and soft tissue growth for improved aesthetics and function. This method offers a reliable, long-term solution for traumatic tooth loss or agenesis.
Area of Science:
- Pediatric Dentistry
- Oral Surgery
- Regenerative Dentistry
Background:
- Missing permanent incisors in children often result from trauma or agenesis.
- Primary tooth autotransplantation offers a novel approach to address these edentulous spaces.
Purpose of the Study:
- To evaluate the long-term success of primary tooth autotransplantation.
- To assess its potential to support bone and soft tissue growth in children.
Main Methods:
- A retrospective study of 40 children undergoing 53 primary tooth autotransplants (canines and incisors).
- Follow-up included clinical and radiological examinations assessing root resorption, bone/soft tissue growth, survival, and success rates.
Main Results:
- A 77% success rate was observed in 22 ongoing transplants.
- Median survival time was 86 months (7.2 years) for all grafts.
- Successful prosthetic rehabilitation was achieved in all cases due to enhanced bone and soft tissue development.
Conclusions:
- Primary tooth autotransplantation is a reliable method for restoring anterior edentulous spaces in children.
- It facilitates co-development of bone and soft tissue, enabling successful prosthetic rehabilitation and high patient satisfaction.
