Summary
Horizontal alveolar ridge distraction in dogs successfully enabled osseointegration of dental implants placed during consolidation. This technique shows promise for narrow alveolar ridges.
Area of Science:
- Oral and Maxillofacial Surgery
- Regenerative Medicine
- Dental Implantology
Background:
- Narrow alveolar ridges present a challenge for dental implant placement.
- Alveolar ridge augmentation techniques are crucial for successful implant osseointegration.
Purpose of the Study:
- To evaluate horizontal alveolar ridge distraction in dogs.
- To assess osseointegration of implants placed in distracted sites during consolidation.
Main Methods:
- Horizontal alveolar ridge distraction was performed using a custom apparatus in beagle dogs.
- Dental implants were placed into the distracted sites 12 days after distraction completion.
Main Results:
- New lamellar bone formation was observed towards the implant surface within 12 weeks.
- Implants achieved full osseointegration with mature lamellar bone by 24 weeks.
Conclusions:
- Horizontal alveolar ridge distraction is a viable technique for narrow alveolar ridges in dogs.
- Osseointegration is achievable with implants placed during the consolidation phase.
