Bone resorption occurring in the alveolar bone after tooth extraction constitutes one of the most fundamental problems that constitute a cosmetic and functional obstacle to treatment with dental implants or fixed prostheses at the site of extraction. A regenerative injectable complex, albumin and platelet-rich fibrin (Alb-PRF), composed of autologous albumin gel and platelet-rich fibrin (PRF) concentrate, it represents a new strategy that combines the advantages of PRF and albumin gel with slow absorption properties. The current case report included the extraction of a single-rooted tooth that was extracted atraumatically. Alb-PRF mixed with alloplast bone graft was used and applied within the socket. The socket was then covered with a piece of gelfoam. The case was followed up for 6 months. Radiographic and clinical measurements were performed, which showed the amount of alteration in both the bone and soft tissue after the extraction. Within the limitations of this case report, we concluded that alveolar ridge preservation using Alb-PRF mixed with alloplast bone graft has good results.
拔牙后牙槽骨中发生的骨吸收是最基本的问题之一，它对拔牙部位的牙种植体或固定修复体治疗构成了美容和功能障碍。一种可注射的再生复合物，白蛋白和富血小板纤维蛋白（Alb-PRF），由自体白蛋白凝胶和富血小板纤维蛋白（PRF）浓缩物组成，它代表了一种新策略，将PRF和具有缓慢吸收特性的白蛋白凝胶的优点结合起来。本病例报告包括一颗单根牙的无创伤拔牙。使用与同种异体骨移植物混合的Alb-PRF并将其应用于牙槽窝内。然后用一块明胶海绵覆盖牙槽窝。对该病例进行了6个月的随访。进行了影像学和临床测量，结果显示拔牙后骨和软组织的改变量。在本病例报告的局限性内，我们得出结论，使用与同种异体骨移植物混合的Alb-PRF进行牙槽嵴保存有良好效果。
