Summary
Autotransplantation of molars and premolars showed continued root growth and pulp survival. However, most cases resulted in ankylosis and root resorption, indicating a need for optimal timing.
Area of Science:
- Dentistry
- Orthodontics
- Oral Surgery
Background:
- Tooth autotransplantation is a surgical procedure to move a tooth to a new socket.
- Assessing long-term radiological outcomes is crucial for treatment success.
Purpose of the Study:
- To evaluate the radiological results of autotransplanted molars and premolars.
- To determine the ideal developmental stage for successful tooth autotransplantation.
Main Methods:
- Retrospective analysis of 40 autotransplantations (20 molars, 20 premolars).
- Radiological assessment of pulp vitality, root growth, ankylosis, and root resorption.
- Data collected from 1979 to 1990 at the University of Geneva.
Main Results:
- Observed persistence of pulp vitality and continuous root growth in transplanted teeth.
- Ankylosis and replacement root resorption were common findings in most cases.
- Results align with previous studies on tooth autotransplantation outcomes.
Conclusions:
- Autotransplantation can achieve pulp vitality and root development.
- Ankylosis and resorption pose significant challenges to long-term success.
- Identifying the optimal developmental stage is key for predictable pulpal and periodontal survival.
