Fibrin-rich blocks with CGFs act as an alternative to bone grafting and can be a predictable procedure for sinus augmentation.

The human study showed the capacity of new bone formation in the maxillary sinus with membrane elevation only and simultaneous implant placement beyond the original sinus floor. New bone formation without additional bone graft in the maxillary sinus is revealed from the clinical, radiographic, and histologic results, but furthermore long-term studies are needed to confirm this.

The flapless transcrestal approach to the sinus augmentation using the HPISE technique with autologous CGF alone could be an alternative to the lateral approach, even at severely resorbed edentulous posterior maxilla with insufficient bone height.

New bone formation in the experimental group was faster and denser than that in the control group. Replaceable bony window, as an autologous barrier, accelerates new bone formation early in the healing phase compared with the collagen membrane over a bone graft in the maxillary sinus. The replaceable bony window and elevated sinus membrane revealed osteoinductive potential.
