Retrieval of migrated dental implant from maxillary sinus using endoscopic sinus surgery

Abstract

Dental implants placed in the maxillary molar region, can get displaced, and can lead to migration of the implant into the maxillary sinus. This is more likely to happen when placement is done immediately after tooth extraction. A male aged 54 years underwent implant placement after extraction, which got displaced and later migrated into the maxillary sinus. The implant was removed by endoscopic sinus surgery. Many techniques for the retrieval of dental implants displaced into the maxillary sinus are described in literature, but the least traumatic and minimally invasive method is endoscopic removal of the implant via maxillary sinus ostium in the middle meatus of the nose.
