Modified osteotome sinus floor elevation using combination platelet rich fibrin, bone graft materials, and immediate implant placement in the posterior maxilla

The osteotome technique is more predictable with simultaneous implant placement when there is <5-7 mm of preexisting alveolar bone height beneath sinus. Proper combination of platelet rich fibrin, mineralized freeze-dried human bone allograft, and autogenous bone has been recommended for this situation. The purpose of this article was to describe the proper method and materials which can grow >10 mm bone with osteotome technique and grafting materials where the edentulous posterior maxilla radio-graphically showed less bone between the alveolar crest and sinus floor.
