Summary
Treating rare edentulous mandible fractures is challenging due to bone atrophy. Special techniques, including single plating and bone grafting, are crucial for successful outcomes in these difficult cases.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthopedic Surgery
Context:
- Edentulous mandible fractures are uncommon, accounting for less than 5% of all mandibular fractures.
- Significant bone atrophy in the edentulous mandible increases the risk of treatment complications.
Purpose:
- To outline effective therapeutic strategies for managing edentulous mandible fractures.
- To address the challenges posed by bone atrophy in fracture treatment.
Summary:
- Fracture treatment in edentulous mandibles differs from dentulous ones, with tension and compression zones being close.
- A single plate is often sufficient for fixation.
- Screws without pretapping are preferred.
- A stronger plate is recommended for weaker bone.
- Cancellous bone grafting is advised for severe atrophy or bone loss.
Impact:
- Implementing these specialized techniques can reduce complications associated with edentulous mandible fractures.
- Improved treatment outcomes for patients with atrophic edentulous mandibles.
