Objective: The aim of present study is to evaluate effect of using two different biomaterials, Bio-oss graft and PRF membrane for ridge preservation after tooth extraction, clinically and radiographically.
Patient&Methods: This study was conducted on 20 patients indicated for extraction, from those attending the outpatient clinics of Oral and Maxillofacial Surgery, Faculty of Dental Medicine, Al-Azhar University Hospitals. Patients were divided into two groups: Group I: Extraction socket preservation with bio-oss graft and PRF membrane (10 patients). Group II: Extraction socket without grafting (10 patients). All patients were evaluated clinically after 24-hour, one week and two weeks for pain and edema. They were also evaluated immediately and after six months for bone gain in height and width using cone beam computed tomography.
Results: The bone width between the two groups was found to be statistically significant where the bone height was not statistically significant between the study and control groups.
Conclusion: Post extraction alveolar ridge resorption is an inevitable process. Bio-oss placed in extraction socket give better bone quality and quantity than empty socket. The PRF membrane is used effectively as a membrane to cover the bone graft.
