Summary
Successful dental implant placement is possible even after severe infection and bone grafting complications. Treating perigraftitis by removing infected bone allows for a third implant to integrate and function long-term.
Area of Science:
- Dental implantology
- Periodontology
- Bone regeneration
Background:
- A prior case reported peri-implantitis and perigraftitis in a dental implant placed in a site previously augmented with alveolar ridge preservation.
- Despite implant removal and repeat bone grafting, infection persisted, necessitating further intervention.
Observation:
- Surgical reentry revealed soft tissue encapsulation of the previous bone graft.
- The encapsulated graft and infected tissue were completely removed.
- A new implant was placed and the defect grafted with demineralized bone allograft.
Findings:
- The third implant achieved osseointegration, evidenced by hard, corticated bone at reentry.
- After 25 months, the implant remained functional and asymptomatic with normal peri-implant bone trabeculation.
Implications:
- Perigraftitis, an infection associated with grafted bone, can compromise dental implant success.
- Complete removal of infected grafted bone is crucial for resolving perigraftitis.
- Successful dental implant therapy is achievable following the resolution of perigraftitis and appropriate bone grafting.
