Autogenous tooth transplantation (ATT) of third molars with complete root formation shows a high survival rate. Utilizing 3D imaging techniques can significantly decrease complications and enhance long-term success for this dental procedure.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Regenerative Dentistry
Background:
- Autogenous tooth transplantation (ATT) of third molars with complete root formation lacks comprehensive long-term outcome data.
- Evaluating survival and complication rates is crucial for establishing ATT as a viable tooth replacement option.
Approach:
- A systematic review and meta-analysis was conducted following PRISMA guidelines.
- Data from 12 studies involving 759 transplanted third molars in 723 patients were pooled.
- Subgroup analyses examined the impact of sample size and 3D imaging techniques on outcomes.
Key Points:
- Pooled survival rate at 1 year was 93.62% (excluding studies with 100% survival).
- Large sample studies demonstrated higher 5-year survival rates.
- 3D techniques reduced root resorption (2.06%) and ankylosis (2.81%) compared to conventional methods (10.18% and 6.49%, respectively).
Conclusions:
- ATT of fully formed third molars is a reliable alternative for missing teeth with promising survival.
- Employing 3D techniques in ATT can mitigate complications and improve long-term prognosis.

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
