摘　　要：BACKGROUND There are some challenges concerning immediate implant placement in the molar region.Platelet-rich fibrin(PRF),an autologous biomaterial,has been used widely for periodontal intra-bony defects,sinus augmentation,socket preservation,and gingival recession.However,the literature remains scarce for reports on immediate implants with PRF,particularly in the case of fresh molar extraction socket.CASE SUMMARY The patient was a 43-year-old woman with maxillary molar vertical crown-root fracture.She underwent flapless immediate implant placement into the fresh molar socket with PRF.At the follow-up visit 15 d post procedure,the vascularization of soft tissue was visible.There was no swelling or pain after the surgery.Six months postoperatively,the regeneration of bone and soft tissues was visible.Subsequently,the definitive restoration was placed.The patient was satisfied with the aesthetic outcomes.CONCLUSION The flapless immediate implant placement into the fresh molar socket with PRF is a feasible procedure.This case report demonstrates that PRF promotes bone and soft tissue regeneration apart from having an enhanced anti-inflammatory ability.Furthermore,the procedure involves a minimally invasive technique,thus reducing the surgical complexity.BACKGROUND There are some challenges concerning immediate implant placement in the molar region.
