Displaced dental implant in the maxillary sinus: A case report and literature review

Abstract

Dental implants (DIs) have been widely used to replace missing teeth worldwide. However, complications such as displacement or migration of DIs into the maxillary sinus may occur. Immediate removal of displaced DIs s (DDIs) is usually recommended to avoid these complications. Here, we report our experience with a rare case of displacement of a maxillary sinus implant that was managed with endoscopic sinus surgery (ESS). A 52-year-old healthy male was referred by his clinician to the rhinology clinic due to a DDI. An earlier sinus computed tomography scan revealed a displaced implant located posteriorly and inferiorly in the maxillary sinus. A displaced maxillary sinus implant should be removed immediately to prevent any eventual complications such as mucosal changes or secondary sinusitis. The authors recommend ESS as the treatment of choice.
