Use of platelet concentrates rich in fibrin and leukocytes in maxillary sinus lift surgery: case report

Abstract

Introduction: The loss of dental units leads to a physiological process of bone resorption, caused by osteoclastic activity, resulting in a decrease in bone thickness in the maxillary sinus region. To rehabilitate this area with dental implants, an adequate amount of bone is essential to ensure implant stability. Bone graft surgeries aim to restore the necessary bone thickness for implant placement. The maxillary sinus lift technique creates a space to be filled with the chosen graft material. Leukocyte- and Platelet-Rich Fibrin (L-PRF), obtained from whole venous blood collected before surgery, promotes angiogenesis, cell proliferation, accelerates bone regeneration, reduces inflammation, and improves patient healing. Objective: To report a clinical case on the use of L-PRF associated with biomaterial in the maxillary sinus lift surgery in a patient with partial edentulism, undergoing rehabilitation with a single dental implant in the maxilla region. Case report: A female patient with a single tooth loss and consequent horizontal bone loss. Guided tissue regeneration (GTR) in height and thickness was performed using L-PRF associated with bone biomaterial during the maxillary sinus lift surgery, followed by the immediate placement of the dental implant and consequent improvement of the stomatognathic system. Conclusion: The use of L-PRF associated with graft material proved to be satisfactory in maxillary sinus lift surgery, being effective, cost-efficient, activating growth factors, assisting in hemostasis, and providing a more comfortable postoperative experience for the patient.
