Although implant placement is regarded as a safe procedure, some reports about displacement or migration to the maxillary cavity have been published. Further migration to other paranasal cavities and spontaneous loss are rare events. A case is reported of a migration to the inferior nasal meatus, which is documented by cone-beam CT, with subsequent spontaneous loss. Mucociliary clearance in combination with a local osteolytic inflammatory process likely caused this unusual migration.
