Simultaneous oroantral communication closure, sinus-lifting, and particulate bone grafting and immediate dental implant perforation.

The aim of this paper is to introduce an alternative technique for the treatment of oroantral communication (OAC). Closure of OAC, reconstruction of the posterior maxilla by sinus-lifting procedure with a particulate xenograft, and implant insertion were performed in the same operation. A lateral antral approach was used in the sinus elevations. The sinus membranes were elevated gently around the perforation area, and then a barrier membrane was used to close the perforation. Care was taken not to extend the perforation. Next, the maxillary sinus was filled with a particulate xenograft, and an implant was inserted simultaneously. Forty-seven and 40 months of clinical and radiographic follows-up revealed healthy and functional implants in the teeth area.
