Abstract: Objective To explore the clinical application value of platelet-rich fibrin in immediate implantation in the aesthetic area. Methods 24 cases of maxillary anterior teeth that could not be retained were retrospectively collected from January 2021 to January 2022 in our hospital. The residual roots were removed, and implants were placed at the same time. The subjects were randomly assigned to two groups (n=12). The control group received a combination of bone substitute and collagen membrane, while the experimental group received a combination of bone substitute and platelet-rich fibrin to guide bone regeneration and soft tissue augmentation. A total of 24 implants were implanted. Results Through clinical research and follow-up observation, the clinical results of the experimental group and the control group were similar. The effect of platelet-rich fibrin in immediate implantation in the aesthetic area was good. The implants had achieved stable osseointegration, the implant dentures had good function, and the patients were satisfied. Conclusion For immediate implantation cases in aesthetic areas, under the premise of strict grasp of surgical indications and operation skills, platelet-rich fibrin can effectively promote the augmentation of soft and hard tissue, and can be popularized in clinical applications.
