Summary
Oral implants can migrate through stable sinus grafts, a rare occurrence. This study reports two cases of implant migration after sinus elevation and graft maturation, highlighting potential causes.
Area of Science:
- Oral surgery
- Dental implantology
- Bone regeneration
Background:
- Implant migration through consolidated grafts is exceptionally rare.
- This report details two cases occurring over six months post-implantation in two-stage sinus grafts.
Observation:
- Two patients underwent sinus elevation and implant placement.
- Clinical and radiographic follow-up revealed implant displacement through stable, histopathologically verified grafts.
Findings:
- Documented implant migration through composite grafts post-maxillary sinus elevation.
- Potential contributing factors include inadequate primary implant stability, Schneiderian membrane perforation, or graft resorption.
Implications:
- Highlights a rare complication in sinus graft procedures.
- Suggests careful evaluation of primary stability, membrane integrity, and graft remodeling is crucial for preventing implant migration.
