An implant displacement into the maxillary sinus could be a complication of implant surgery in the upper jaw. In such cases, implant removal is needed to avoid the occurrence of sinus pathologies. Piezosurgery techniques could assure safer management of such complications because of clear surgical visibility and a selective ability to cut. The aim of this report is to present a case of an implant-related oral surgery complication that was resolved by means of a piezosurgery technique.
