Summary
This study presents a novel technique for anterosuperior alveolar distraction osteogenesis in edentulous patients. Using an implant-supported provisional prosthesis prevents bone inclination, offering a viable solution for jaw augmentation.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Distraction Osteogenesis
Background:
- Alveolar bone augmentation is crucial for dental implant success.
- Distraction osteogenesis is an effective method for bone regeneration.
- Preventing lingual inclination during distraction is a common challenge, especially in edentulous cases.
Observation:
- A 69-year-old woman underwent anterosuperior alveolar distraction osteogenesis.
- A distraction device was used with an implant-fixed provisional prosthesis.
- The device's rod was positioned on the labial side of the prosthesis to counteract lingual soft tissue forces.
Findings:
- The mandibular bone was successfully distracted obliquely by 0.3 mm every 2 days.
- The technique effectively prevented lingual inclination during the distraction period.
- Implant insertion was performed with a favorable prognosis.
Implications:
- This implant-fixed provisional prosthesis method offers a practical solution for distraction osteogenesis in edentulous patients.
- It overcomes limitations of previous methods that required natural tooth support.
- This technique expands the applicability of distraction osteogenesis for complex alveolar reconstructions.
