As an increase in attempt to rehabilitate compromised maxillary arch with sinus lift, the complications are becoming more frequent. One of them is the displacement of dental implants into the maxillary sinus which can occur during initial or second stage surgery. The present report is discussing a case dislodged implant during second stage surgery and its management. A male patient aged 33 years reported with missing teeth in right posterior back tooth region. Implant was placed with delayed protocol at sites 16 and 17. The patient was recalled after 6 months for second stage surgery. While removing the cover screw and due to the obvious reasons of lack of osseointegration; the dental implant got displaced in to the maxillary sinus. OPG was taken to locate the implant and the implant was removed using Caldwell-Luc (CL) operation. Lack of bone quality and quantity, failure to repair of Schneiderian membrane, lack of primary stability. Inability to achieve osseointegration are most common causes. It is advisable to remove displaced implant as early as possible with appropriate approach to prevent complications.
