ABSTRACT
Bone grafts and its substitutes are commonly used in periodontics to enhance bone formation and periodontal regeneration. Allografts, derived from human donors, support new bone growth and are biocompatible, with reduced disease transmission risk due to rigorous screening. Combining bone grafts with growth factors can further improve treatment outcomes. Platelet Rich Fibrin (PRF) releases growth factors that enhance regeneration. This study evaluates the effectiveness of combining processed fresh frozen bone allograft (FFBA) with PRF mambrane for treating periodontal bone defects. The FFBA was prepared from bone chips collected from systemically healthy patients in an aseptic environment during orthopedic surgeries, which was then processed and tested for microbiological and cytotoxicity concerns using Human Osteosarcoma (MG-63) and Normal Mouse Fibroblast (L929) cell lines. PRF was prepared by centrifuging blood collected from patients at 2300 rpm for 12 min. A case study comprising of ten patients with chronic periodontitis was conducted, Clinical and radiographic measurements, including plaque index (PI), gingival index (GI), probing depth (PD), and bone defect fill percentage using radiographs were recorded at baseline and nine months. Descriptive statistics (Mean ± SD), a 5% significance level, and 90% confidence intervals were used. Paired t-tests showed significant improvements in GI (p < 0.001), PI (p < 0.001), PPD (p < 0.001), and Bone defect fill (p < 0.001). The study concluded that using processed fresh frozen bone allograft with PRF positively affects the treatment of periodontal osseous defects.
