Periodontal intrabony defects pose a significant challenge in clinical dentistry due to their complex anatomy and limited regenerative potential. Recent advancements in biomaterials and regenerative techniques have introduced novel approaches to enhance periodontal healing. This study evaluates the clinical and radiographic outcomes of using nano-hydroxyapatite (nHA) and zinc-substituted nano-hydroxyapatite (Zn-nHA) in combination with advanced platelet-rich fibrin (A-PRF) blocks for the treatment of periodontal intrabony defects. Nano-hydroxyapatite, a biomimetic material, has shown promise in promoting bone regeneration due to its osteoconductive properties. Zinc substitution further enhances its biological activity by incorporating antimicrobial and osteoinductive characteristics. Advanced PRF, a second-generation platelet concentrate, provides a scaffold rich in growth factors and cytokines, which synergistically supports tissue regeneration.
