Purpose: The purpose of the present study was to evaluate the predictability of bone formation in the maxillary sinus using CGF a graft material.

Materials and methods: 10 patients were consecutively treated with sinus floor elevation via the lateral window approach. The lateral bony window was created by piezoelectric saw and the sinus membrane was elevated to make new compartment. After RBM surfaced dental implants were placed simultaneously, the collected CGF was applied to support sinus membrane over implant apex and the bony portion of lateral window was repositioned to seal the lateral window. Internal sinus elevation was performed using HPISE technique. Histologic data were obtained in 2 patients at the time of second stage surgery.

Results: New bone consolidation in the maxillary sinus was observed on radiographic and histologic evaluation.

Conclusion: This study suggests that simultaneous placement of dental implants and injection of CGF as graft material appears to be safe and alternative procedure for maxillary sinus augmentation.
