摘要
富血小板纤维蛋白(PRF)是一种立体三维网状结构的第二代血小板浓缩物,它能够调节炎症,促进组织愈合。并且能够缓慢持续释放多种生长因子。大量文献报道PRF可以促进口腔软硬组织的愈合,但尚未将其应用于临床牙再植的治疗中。本文联合自体PRF颗粒对1例撕脱2 h且干燥保存的离体牙进行延迟再植、复位固定及后续牙髓治疗。随访1年,脱位牙恢复良好,达到牙周膜性愈合,没有出现牙根吸收,且牙槽骨高度得到恢复。
PRF（ platelet rich fibrin） is a kind of second generation platelet concentrate with a three dimensional reticular structure which can regulate inflammation,accelerate tissue healing,and release a variety of growth factors slowly and continuously. However,no clinical study has used PRF for the treatment of avulsed tooth. In this study,a delayed and dry-reserved avulsion tooth was replanted with autologous PRF. 12-month follow-up showed that the tooth recovered well,the peridental membrane was healed,no root resorption occurred,and the height of alveolar bone was restored.
