Summary
This case report details a novel surgical technique for vertical alveolar ridge augmentation using osteogenesis distraction. The procedure successfully achieved 7 mm of vertical bone gain in a patient with an atrophied mandible.
Area of Science:
- Oral and Maxillofacial Surgery
- Regenerative Medicine
- Biomaterials Science
Background:
- Alveolar ridge atrophy presents challenges for dental implant placement.
- Osteogenesis distraction, a technique from orthopedic surgery, offers a potential solution for bone regeneration.
- This study explores the application of osteogenesis distraction for vertical ridge augmentation in the mandible.
Observation:
- A surgical technique utilizing intraosseous distraction implants was employed for vertical ridge augmentation.
- The procedure involved horizontal and vertical osteotomies, followed by controlled distraction of the bone segment.
- A 30-year-old female patient with an atrophied anterior mandibular ridge was treated.
Findings:
- The distraction device facilitated a daily distraction of 1 mm for 10 days, achieving a total vertical augmentation of 7 mm.
- The patient experienced no complications or discomfort during the treatment period.
- Histologic analysis of a biopsy specimen revealed woven bone formation approximately 75 days post-procedure.
Implications:
- This surgical technique demonstrates a viable method for significant vertical alveolar bone augmentation.
- Osteogenesis distraction shows promise for enhancing bone volume in atrophic ridges, facilitating dental implant success.
- Further research may validate this technique for broader clinical application in maxillofacial reconstruction.
