Evaluation of Nanocrystalline Hydroxyapatite Plus Platelet-Rich Fibrin as A Grafting Material Around Dental Implant After Narrow Alveolar Ridge Splitting

Abstract

Aim: This study was carried out to evaluate clinically and radiographically using of nanocrystalline hydroxyapatite (NcHA) and platelet-rich fibrin (PRF) as a grafting materials around the implant after narrow alveolar ridge splitting and expansion by piezoelectric surgery. Subjects and methods: twenty systemically healthy patients with partial edentulous narrow maxillary alveolar ridges were selected from those attending at the Out-Patient Clinic, Oral Medicine and Periodontology Department, Faculty of Dental Medicine, Al-Azhar University, Assiut Branch. Then they divided randomly into the following equal groups. First Group, ten patients with partial edentulous narrow maxillary anterior alveolar ridges, treated by piezoelectric ridge splitting and expansion with simultaneous implant placement into their ridges. Second Group, ten patients with partial edentulous narrow maxillary anterior alveolar ridges treated by piezoelectric ridge splitting and expansion with simultaneous implant placement into their ridges; combined with application of nanocrystallin hydroxyapatite bone graft mixed with platelet rich fibrin (PRF). Patients were evaluated clinically to assess probing depth and implant stability quotient, and radiographically to assess the alveolar ridge width, marginal bone loss, and bone density measurement parameters at baseline, 6, 9, and 12 months. Results: Among the studded groups, there is a high statistically significant difference between the clinical and radiographic measurements. Conclusion: Usage of combination of nanocrystallin hydroxyapatite bone graft and platelet rich fibrin as a grafting materials around the implant after narrow alveolar ridge splitting and expansion by piezoelectric surgery appeared significantly superior to immediate implant placement alone. INTRODUCTION Dental implants provide a gold standard method of successful and predictable treatment of partial or complete edentulism. To achieve long-term optimal functional and esthetic results with dental implants, one major prerequisite is sufficient bone quantity and quality at the recipient site. (1)
