Summary
Horizontal distraction osteogenesis offers a novel solution for severe maxillary tuberosity bone defects. This technique successfully reconstructed significant bone loss, enabling dental implant placement and fixed denture restoration.
Area of Science:
- Oral and Maxillofacial Surgery
- Regenerative Medicine
- Dental Implantology
Background:
- Severe bone loss in the maxillary tuberosity presents significant surgical and prosthetic challenges.
- Traditional bone grafts have limited success rates due to the region's delicate anatomy and proximity to the maxillary sinus.
Observation:
- A 45-year-old male patient presented with a severe bone defect in the maxillary tuberosity following cyst enucleation.
- The defect extended superiorly to the zygomatic buttress and posteriorly to the hamular notch.
Findings:
- A novel technique utilizing horizontal distraction osteogenesis was employed for reconstruction.
- A bone segment was osteotomised and distracted 15 mm distally, followed by implant placement and a fixed denture restoration after consolidation.
Implications:
- Transport distraction osteogenesis is a viable method for reconstructing extensive alveolar bone defects, even those extending to the cranial base.
- Distalization of adjacent alveolar bone segments provides an effective approach for severe maxillary tuberosity reconstructions.
