Sinus Lifting and Leucocyte- and Platelet-Rich Fibrin

Abstract

The insufficient alveolar bone height due to the maxillary sinus in the posterior maxilla and postextraction bone resorption may limit implant placement. The sinus lifting procedure creates space between the maxillary alveolar bone and the Schneiderian membrane, which is filled with graft materials to maintain adequate space for new bone formation. Leucocyteand platelet-rich fibrin (L-PRF)-mixed bone substitute or L-PRF has been used solely as a graft material for sinus lifting. The clinical and radiological findings of the application of PRF for sinus augmentation have been shown to have good results regarding new bone formation. The L-PRF can be an efficient biomaterial for graft particles in maxillary sinus lifting.
