Evaluation of beta tricalcium phosphate mixed with platelet rich fibrin for rehabilitation of atrophic maxilla with implant installation

Restoration of severely atrophic edentulous posterior maxilla with implant installation could be impossible unless, augmentation of that area was done. This study was made to evaluate augmentation of atrophic maxillary bone using beta tri-calcium phosphate (B-TCP) granules mixed with platelet-rich fibrin (PRF) for sinus lift and then implant installation 4 months latter.

Patients and methods: 15 patients were consecutively included in this study. beta tri-calcium phosphate (B-TCP) granules mixed with platelet-rich fibrin (PRF) were used to elevate the sinus floor as a preparatory step for dental implant installation (friadent dental implants) which were inserted 4 months latter. A sinus lift was performed by making a bony cortical window at the sinus wall. The sinus mucosal lining was elevated and the previous mix was packed under the sinus mucosal lining. Four months latter, the dental implants were installed at the area of previous augmentation. Clinical and radiographic follow-up were performed up to 1 year after implant installation.

Results: The procedures were well tolerated by the patients under local anesthesia. The implants showed good stability during installation as well as at 12 months after installation. The X-ray revealed complete or near complete degradation of the augmenting mix with concurrent bone substitution in the majority of cases at 12 months period post grafting. Conclusions:The present study showed consistent bone formation at the maxillary sinus floor following use of mixture of both beta tri-calcium phosphate (B-TCP) granules and platelet-rich fibrin (PRF) as well as after implant installation. This study suggests that, use of this mixture can reduce long time needed for new bone formation, as well as the morbidity risk related to harvesting autogenous bone graft.
