<br/><br/> Objectives: The aim of this study is to evaluate both clinically and radiographically the efficacy of Platelet-Rich Fibrin as a graft material in osteotome-mediated sinus floor elevation technique with simultaneous implant  placement. Materials and methods: Sixteen dental implants were placed simultaneously with osteotome sinus floor elevation in the posterior maxillary area and were divided into groups. Group (A): Eight dental implants were placed simultaneously with osteotome sinus floor elevation using platelet-rich fibrin as a graft material (study group). Group (B): Eight dental implants were placed simultaneously with osteotome sinus floor elevation with no graft  material (control group). Clinical evaluation for all cases immediately after surgery, 14 days postoperatively, 6 months after surgery and 9 months after surgery. Radiographic evaluation was performed using standardized digital radiographs (panoramic radiograph) immediately after surgery, 6 months after surgery and 9 months after surgery. Analysis of data was performed using SPSS 17 (Statistical Package for Scientific Studies) for Windows
