Unexpected displacement of a dental implant into the maxillary sinus is an unusual but potential complication in dental procedure. A dental implant that migrates into the maxillary sinus often develops paranasal sinusitis and cause diverse peri-implant soft tissue complications. A 59-year-old man complaining of nasal obstruction for several months presented with a huge polypoid mass in the nasal cavity. He had undergone a dental implant procedure in the maxilla at a dental clinic seven years ago. The implant fixture was found displaced to the maxillary sinus. The migrated fixture and nasal mass were removed by endonasal endoscopic surgery and mini Caldwell-Luc operation. The pathology was diagnosed as an inverted papilloma. To our knowledge, this is the first case reported in the literature regarding a dental implant complication that developed independently of sinonasal inverted papilloma.
