Abstract
INTRODUCTION: Furcation involvement (FI) in multi-rooted teeth is challenging for proper oral hygiene, clinical treatment, and leads to poor prognosis. Traditional treatment modalities often result in sacrificing periodontal bone. Multiple regenerative approaches have been attempted to treat furcation defects, but complete regeneration of the periodontal apparatus in grade III furcation has not been reported. Platelet rich fibrin (PRF) shows great potential in enhancing tissue regeneration, angiogenesis, and prevention of infection. This case report introduces a treatment combining allogenic bone grafts with PRF to treat mandibular grade III furcation lesions with a one-year follow-up. CASE PRESENTATION: Two patients presented with grade III FIs of the mandibular first molars, with intrabony defects requiring guided tooth regeneration (GTR). PRF was collected from each patient to serve as biologics, by mixing with allogenic bone graft, and packed into the furcation and intrabony defects. The PRF membranes were also used for space maintenance. The twelve-month postoperative follow-up demonstrated quicker tissue healing, significant pocket reduction, clinical attachment gain, as well as radiographic bone fill in both cases. CONCLUSION: Successful periodontal regeneration of grade III furcation defects can be achieved by using PRF in combination with bone allograft.
