Abstract: The maxillary sinus floor elevation is a key technique for restoring the vertical bone volume in the patient’s posterior region. However, the maxillary sinus floor elevation still has limitations such as significant trauma, sometimes requiring a second surgical area, and a long treatment cycle. These limitations are closely related to its osteogenic mechanism and the bone augmentation protocol. The article summarizes the evolution of the “gold standard” of bone augmentation materials for maxillary sinus floor elevation from the perspectives of spatial maintenance ability and new bone formation quality based on the mechanism of sinus cavity osteogenesis, then focuses on the current clinical application status of simply using deproteinized bovine bone matrix, in order to provide ideas for standardized clinical treatment and conversion research.
