The inclusion criterion was that less 5mm of alveolar bone in the floor of the sinus. Endosseous titanium implants were placed 6 months after the grafting procedure. Bone biopsy specimens were obtained from the grafted site 6 months of healing at the time of implant placement. Radiographic analysis was realized by pre-post operative panoramic-rx.
