Abstract
Objective: The predictability and long-term success of periodontal regeneration begins with oral hygiene education, dis-ease management, and an individually tailored periodontal maintenance protocol. The treatment outcomes could be enhanced when biologics and bone grafts are combined. The aim of this report was to describe the outcome of two complex infrabony defects in the same patient treated with recombinant human platelet-derived growth factor-BB (rhPDGF-BB) and freeze-dried bone allograft (FDBA) over 10 years.Case presentation: Two complex infrabony defects were treated following guided tissue regeneration principles and procedures. Full-thickness flaps were raised to allow visualization of the defects. The areas were debrided, and exposed root surfaces were planed. FDBA and rhPDGF-BB were combined to fill both de-fects. A collagen membrane was used over the bone graft in one case. The flaps were reapproximated to achieve primary clo-sure. The patient was seen for regular periodontal maintenance visits and clinical and radiographic follow-ups over 10 years. Throughout the examination periods, the probing depths im proved without bleeding on probing, and there was radiographic evidence of bone regeneration. Conclusion: The growth factor-infused bone graft was successfully utilized for periodontal re-generation in complex bony defects. (Quintessence Int 2023;54: 802-807; doi: 10.3290/j.qi.b4240197)
