Abstract

Background: Sinus augmentation with various types of materials had become a standard procedure to increase bone height in the posterior maxilla, allowing placement of an implant. Aim of the study: To evaluate and compare clinically and radiographically the bone formation around simultaneous implant placed in the maxillary sinus with plasma rich protein (PRP) loading and autogenous chin corticocancellous particulate. Patients and methods: Twelve patients with moderate vertical posterior maxillary bone height (4-6 mm) were included in this study and randomly divided into two equal groups' six patients each. Group I received PRP gel loaded around and above the implant. Group II augmented with chin corticocancellous bone. Collagen membrane was applied to cover the lateral bone window in both groups. Degree of mineralization and height of the bone around implant were evaluated using Cone Beam Computed Tomography (CBCT) three and six months postoperatively. Results: Radiographically, densitometric values of the bone surrounding implant via CBCT measurements were higher in autogenous bone group than PRP group at both three and six months postoperatively with statistically significant difference. As regard to bone height, measurements were higher in autogenous bone group than PRP group at both three and six months postoperatively with statistically significant difference between both groups at three months while non significance at six months postoperatively. Conclusion: Positive effects of both PRP and autogenous bone graft on bone density and height for sinus floor augmentation with immediate implantation has been documented.
