Abstract: This case report describes a minimally invasive technique established by PESS, in which only platelet-rich fibrin (PRF) was used as a bone graft, combined with the endoscopic lifting of the maxillary sinus floor through the crest of the alveolar ridge, and immediate implantation at the periapical infected site with residual bone height less than 1 mm. Finally, the treatment time was successfully shortened, the implant stability was maintained, and the masticatory function of the posterior teeth was guaranteed.
