Management of maxillary sinus perforation at the time of immediate implantation with sinus-socket osteotomy (SSO) technique.

Immediate implantation related to socket and vital anatomy of the maxillary sinus area requires careful consideration. One major complication that may occur during immediate replacement of posterior teeth is maxillary sinus membrane perforation. To date, no specific technique has been proposed to manage this problem so that implant insertion remains possible during the same surgery. In this paper, we introduce a method to manage this type of perforation and while performing simultaneous implantation. We used sinus-socket osteotomy (SSO), a modified osteotomy technique for socket preparation that blocks sinus perforation with autogenous bone. A 12-month follow-up showed that this technique was clinically successful and reduced the overall treatment time. However, this advanced method requires a skillful surgeon.
