Abstract

Atrophy in the edentulous maxilla typically consists of vertical bone loss in the posterior maxilla due to centrifuged to obtain PRF. Mineralized cancellous bone allograft (Zimmer Puros®) was mixed with PRF and applied membranes were placed over augmented area. Evaluation was carried out before and six months after surgery - tion to evaluate quality of bone cover membrane permitted rapid tissue reparation, high bone quality was detected in sites augmented with bone allograft bone volume after 6 months and the vertical bone augmentation increased at about 10 mm. Conclusion: Based on the preliminary case series, the combination of PRF membrane and PRF mixed with bone allograft represents a predictable method of augmenting the sinus as well as the anterior maxilla to achieve rehabilitation of the atrophic maxilla with dental implants.
