Abstract: Severe periodontitis is a common disease leading to bone absorption and loss of natural teeth. Patients often cannot get good effect of dental implant due to obvious vertical and horizontal bone defects. Researches at home and abroad have shown that variety of alveolar bone augmentation techniques have been used to reconstruct the alveolar bone contour in order to provide the initial stability of implant，while patients with severe periodontitis may experience collapse of osteogenic space and poor initial closure of soft tissue as a result of severe bone absorption. Advanced platelet-rich fibrin（A-PRF）and injectable platelet-rich fibrin（i-PRF），as platelet concentrates，have attracted much attention since they are good for shaping and tissue healing and their contribution to solving implant problems in patients with severe periodontitis. This paper reviews the research progress of A-PRF and i-PRF used in alveolar bone augmentation.
