Late displacement of a dental implant into maxillary sinus.

Dental implants can be accidentally introduced into the maxillary sinus both during and after surgical installation. Both situations are uncommon and usually induce sinusitis or others important complications.1 The aim of the present study was to report a rare clinical case of late displacement of a dental implant into the maxillary sinus, in which a Caldwell-Luc (CL) approach was performed, followed by the reconstruction of the anterior maxillary sinus wall using a titanium mesh.
