Summary
Mandibular bone harvesting for alveolar defects has low morbidity. Harvesting from the retromolar region with third molar removal was best accepted by patients.
Area of Science:
- Oral and Maxillofacial Surgery
- Regenerative Medicine
- Dental Implantology
Background:
- Mandibular bone grafts are crucial for alveolar defect reconstruction.
- Assessing donor site morbidity and patient acceptance is vital for procedure selection.
Purpose of the Study:
- To evaluate the objective and subjective morbidity associated with mandibular bone harvesting.
- To compare patient acceptance across different mandibular donor sites.
Main Methods:
- A study involving 45 patients undergoing mandibular bone harvesting from chin or retromolar regions.
- Evaluation included medical records, clinical/radiographic exams, and patient questionnaires up to 12 months post-surgery.
- Three groups were assessed: chin harvest, retromolar harvest, and retromolar harvest with third molar removal.
Main Results:
- No significant difference in acceptance between chin and simple retromolar harvest.
- Significantly higher patient acceptance for retromolar harvest combined with third molar removal (9.3/10).
- Most sensory disturbances resolved within 2 months; persistent issues were rare and not objectively confirmed.
Conclusions:
- Mandibular bone harvesting is a well-accepted procedure for alveolar reconstruction with minimal morbidity.
- Combining retromolar bone harvest with third molar extraction offers the highest patient acceptance.
- The study supports retromolar bone harvesting as a favorable option for reconstructive procedures.
