Clinical application of platelet-rich fibrin as the sole grafting material in maxillary sinus augmentation

摘要

Platelet-rich fibrin (PRF) was first described by Choukrounet al1 in 2001. PRF is derived from an autogenous preparation of concentrated platelets without any manipulation.PRF is a consistent fibrin biomaterial enriched with platelets and growth factors, after starting from ananticoagulant-free blood harvest. Recently, PRF has beenused as an autologous grafting material because of itsability to accelerate physiologic wound healing and newbone formation. The present study reports a patient whoreceived maxillary sinus floor augmentation with simultaneous implant placement using PRF as the sole graftingmaterial with radiologic and histologic analyses.
