Summary
Distraction osteogenesis, a method involving shortening and lengthening, successfully reconstructed a patient's mandible after segmental resection. This technique facilitated new bone formation and dental implant osseointegration, proving a viable reconstructive option.
Area of Science:
- Oral and Maxillofacial Surgery
- Regenerative Medicine
- Orthognathic Surgery
Background:
- Distraction osteogenesis (DO) is a standard surgical procedure for bone reconstruction.
- This study investigates DO using a shortening and lengthening method for mandibular reconstruction post-resection.
Observation:
- A 74-year-old female patient underwent mandibular reconstruction using an intraoral distraction device.
- The procedure involved initial shortening followed by lengthening at 0.8 mm/day for 21 days.
Findings:
- Radiographic evaluation confirmed new bone formation at the distraction site.
- A dental implant placed eight weeks post-distraction achieved complete osseointegration.
- The patient experienced an uneventful clinical course.
Implications:
- Shortening and lengthening DO is a feasible technique for mandibular reconstruction after segmental resection.
- This method supports successful dental implant placement and osseointegration.
- DO offers a promising alternative for complex mandibular defects.
