EVALUATION OF COMBINATION OF BIPHASIC CALCIUM PHOSPHATE AND PLATELET-RICH FIBRIN AS GRAFTING MATERIAL FOR SINUS LIFT AUGMENTATION

Abstract

INTRODUCTION: The performance of implant surgery in the posterior maxilla often poses achallenge due to insufficient available bone. Sinus floor elevation is developed to increase needed vertical height to overcome this problem. A lot of grafting materials has been used to augment subsinus area. The present study describes and reports a simple, safe and predictable bone graft mixture for the sinus lifting procedure. Recently, several authors have shown that simultaneous sinus lift and implantation using autologous platelet-rich fibrin combined with biphasic calcium phosphate as a grafting material is a reliable procedure promoting bone augmentation in the maxillary sinus. OBJECTIVE: This study is aiming to evaluate bone formation after maxillary sinus membrane elevation using lateral window technique and simultaneous implant placement with using biphasic calcium phosphate combined with pletelet rich fibrin as a grafting material. MATERIALS AND METHODS: The present study was conducted on ten patients with age ranged from 30-50 years seeking implantation of their lost posterior maxillary teeth, and has limited bone height below the floor of the maxillary sinus, secondary to sinus pneumatization. Patients were selected on the basis of history, clinical examination and radiographic examination using panoramic radiography and CBCT. CONCLUSION: PRF in addition to BCP may favor the formation of new bone after maxillary sinus augmentation. The effectiveness of PRF depends not only on its features but also the properties of coadministered grafting material.
