摘要: 富血小板纤维蛋白(platelet-rich fibrin,PRF)作为第二代自体血小板浓缩物,凭借其良好的生物相容性和促进骨再生的能力,在口腔种植、颌面外科等领域得到广泛应用。PRF通过三维纤维蛋白网状结构持续释放生长因子促进成骨细胞活化、血管生成及骨组织重塑。在上颌窦底提升、骨增量、拔牙位点保存及即刻种植等手术中,PRF表现出优异的成骨效果和组织愈合能力,提高了种植体的稳定性和留存率。此外,在药物相关性颌骨坏死患者的治疗中PRF可有效抑制感染、减轻炎症反应,并促进组织愈合。然而,其临床效果易受个体生理差异、制备方法及降解速度等因素影响,部分研究中PRF的长期成骨效果表现不一,尤其在大范围骨缺损修复中,单独使用PRF难以满足需求。研究表明,通过优化离心参数、采血管材质及纤维结构可增强PRF的生物活性,而将PRF与骨增量材料、抗菌药物及生物支架结合,可进一步提升其在复杂病例中的应用潜力。此外,PRF联合纳米材料及水凝胶支架在血管生成和组织修复方面表现出一定优势,但目前尚缺乏长期随访数据。综上,PRF在骨再生领域具有广阔应用前景,但仍需进一步完善标准化制备流程和多学科联合应用策略,以提高其临床应用的稳定性和有效性。

Abstract: Platelet-rich fibrin (PRF), a second-generation autologous platelet concentrate, has been widely used in oral implantology and maxillofacial surgery due to its excellent biocompatibility and bone regeneration capacity. PRF facilitates osteoblast activation, angiogenesis, and bone remodeling by sustained release of growth factors through its three-dimensional fibrin network. It has shown significant potential in sinus floor elevation, bone augmentation, extraction site preservation, and immediate implant placement, improving implant stability and survival rates. Additionally, PRF has shown efficacy in the treatment of medication-related osteonecrosis of the jaw (MRONJ) by reducing infection, alleviating inflammation, and promoting tissue healing. However, PRF's clinical outcomes are influenced by individual physiological differences, preparation methods, and degradation rates. PRF's long-term osteogenic effects, especially in severe bone defects, remain inconsistent. Optimizing centrifugation parameters, blood collection tube materials, and fiber structure, as well as combining PRF with bone grafts, antimicrobial drugs, and biomimetic scaffolds, can enhance its performance. Additionally, PRF combined with nanomaterials and hydrogel scaffolds shows potential advantages in angiogenesis and tissue regeneration, though long-term follow-up data remain limited. In conclusion, PRF holds significant promise in bone regeneration. However, further studies are required to establish standardized preparation protocols and multidisciplinary strategies to improve its clinical stability and efficacy.
