Summary
Wisdom tooth transplantation is a predictable treatment for tooth replacement, achieving a 94.7% success rate. Careful graft selection and removal are key to successful outcomes in young patients.
Area of Science:
- Dentistry
- Oral Surgery
- Regenerative Medicine
Background:
- Wisdom tooth transplantation offers a biological solution for replacing missing premolars or molars.
- This procedure is particularly relevant for adolescents and young adults facing tooth agenesis or early molar loss.
Purpose of the Study:
- To retrospectively evaluate the success rate and influencing factors of wisdom tooth (third molar) transplantation.
- To assess the predictability of wisdom tooth transplantation as a treatment option.
Main Methods:
- A retrospective review of 57 wisdom tooth transplants was conducted.
- Evaluations included preoperative assessment (root development, extraction site, indication), postoperative clinical assessment (gingivitis, probing depth, mobility, percussion), and radiological assessment (dentin deposition, periapical bone, root growth).
- Success was defined as a vital pulp and a periodontally healthy state.
Main Results:
- The overall success rate was 94.7% (54 out of 57 transplants).
- Factors such as root growth stage (50-75% development), extraction site, and initial transplant feasibility did not significantly influence success rates (p=1, p=0.45, p=0.56, respectively).
- Only three transplants failed due to pulpal necrosis with apical periodontitis.
Conclusions:
- Wisdom tooth transplantation demonstrates a high success rate and can be considered a predictable treatment.
- Careful selection and gentle handling of the donor tooth are crucial for successful outcomes.
- This procedure provides a viable option for biologically fixed tooth replacement in specific dental scenarios.
