The buccal fat pad is largely involved to close oro-antral communication (OAC) . The implant rehabilitation of the maxillary posterior area after OAC is a surgical challenge. The difficulty of this rehabilitation remains in the absence of a lateral and crestal bone wall.

The buccal fat pad lift was performed under general anaesthesia. This involved lifting the buccal fat pad and the sinus mucosa, which they were fused and filled the gap with a biomaterial. The osteogenic properties of the environment will enable osseointegration of the biomaterial.

This technique requires a relevant surgical experience. It is a reliable and valid surgical solution to rehabilitate the maxillary posterior area for dental implant placement.
