Summary
A porcine cortical bone barrier effectively facilitated bone healing in a mandibular cyst defect, significantly reducing cavity size. This method promotes regeneration and avoids a second surgery for membrane removal.
Area of Science:
- Oral and Maxillofacial Surgery
- Regenerative Medicine
- Biomaterials Science
Background:
- Mandibular inflammatory cysts require effective management following enucleation to ensure complete bone regeneration.
- Maintaining the structural integrity of the surgical defect is crucial for successful bone healing and preventing complications.
- Alternative methods for defect management include various barrier membranes and bone graft materials.
Observation:
- A case study involved a 36-year-old male with a large mandibular inflammatory cyst treated with enucleation and coverage using a porcine cortical bone barrier (Bone Lamina).
- Postoperative assessments included panoramic radiographs and cone-beam computed tomography (CBCT) scans at multiple intervals up to 24 months.
- Clinical and radiographic examinations revealed uneventful healing and progressive filling of the residual cavity.
Findings:
- The porcine cortical bone barrier successfully prevented tissue collapse and maintained the defect's structural integrity.
- Radiographic analysis demonstrated significant bone regeneration, with cortical thickness increasing over time.
- The residual cavity volume decreased by 92.1% at 12 months and 96.53% at 24 months, indicating substantial bone fill.
Implications:
- The use of a porcine cortical bone barrier is a viable strategy for managing bone defects after mandibular cyst enucleation.
- This approach promotes natural bone regeneration and simplifies the treatment process by utilizing a resorbable material.
- The findings suggest potential benefits for similar regenerative procedures in oral and maxillofacial surgery.
