VALENTINI-NETO, Rodolpho et al. Dental Implant Dislocation to Maxillary Sinus. Case report. Rev. cir. traumatol. buco-maxilo-fac. []. 2011, 11, 1, pp. 15-20. ISSN 1808-5210.

The residual alveolar ridges may be unfavorable for implant placement. The edentulous maxilla is often challenging for the oral surgeon because of the lack of bone as a consequence of alveolar ridge resorption and/or maxillary sinus pneumatization. Accidents or complications may occur when some of these issues are not being known. This article reports one case of implant displaced into the maxillary sinus, 27 days after sinus bone augmentation with simultaneous dental implant installation, causing moderated sinusitis symptoms. The implant was removed through oral cavity access to maxillary sinus.
