Summary
Apical root resection alone may not resolve symptoms of apical fenestration. Guided bone regeneration with decortication successfully treated persistent symptoms and promoted significant bone gain, offering a conservative management approach.
Area of Science:
- Dentistry
- Oral Surgery
- Regenerative Medicine
Background:
- Apical fenestration management traditionally involves apical root resection, with limited case studies showing symptom resolution.
- This approach has shown inconsistent results, sometimes leading to persistent symptoms and further bone loss.
Observation:
- A patient with persistent discomfort and bone loss post-apical root resection due to apical fenestration was treated with corrective surgery.
- The corrective procedure incorporated guided bone regeneration and decortication of the cortical plate to stimulate bleeding.
Findings:
- The corrective surgery successfully resolved the patient's clinical symptoms within weeks.
- Follow-up imaging confirmed apical root coverage, and 3D analysis revealed approximately 200 mm³ of bone gain and 2 mm linear bone gain.
- This demonstrates a significant positive outcome compared to the initial treatment.
Implications:
- Guided bone regeneration combined with decortication offers a viable and conservative alternative for managing complex apical fenestration cases.
- This approach can effectively address persistent symptoms and promote substantial bone regeneration without compromising the root apex.
- The findings suggest a potential improvement in treatment protocols for root fenestration, enhancing patient outcomes.
