Abstract

Aim: The aim of this study was to evaluate the effectiveness of platelet rich fibrin (PRF) as sole graft material versus Nano crystalline hydroxyapatite in maxillary sinus augmentation with implant placement simultaneously.
Patients and Methods: This was a randomized controlled clinical trial conducted on 18 patients suffering from atrophied maxillary ridge (less than 5 mm in bone height) for implantation indicating the need for maxillary sinus floor augmentation before implant placement. Group (A) received sinus augmentation with nano crystalline hydroxyapatite with immediate implantation (Nano bone ARTOSS GmbH hydroxyapatite particles) and Group B received sinus augmentation with PRF as sole graft material with immediate implantation. All patients were followed up for 6 months recording the progress of the healing both clinically and radiographically via CBCT and to evaluate the new bone formation.
Results: Surgeries went uneventful in patients of both groups. No notable complications occurred during the surgical procedures and the healing period of the two groups. Radiographic results after 6 months showed that there was no statistically significant difference between the two groups. The highest mean value was found in (Group B) while the least mean value was found in (Group A). All implants were clinically stable at the time of abutment insertion, 6 months after sinus augmentation.
Conclusions: The use of the PRF as a sole graft material in maxillary sinus augmentation proved to be a successful material that offers sufficient amount of natural bone in the sinus that cover all the surface of the inserted implant.
