Research progress on application of concentrated growth factors in maxillary sinus augmentation and sinus mucosal repair

Abstract

The maxillary sinus is pyramid-shaped with a volume of 12-15 cm3, located in the maxilla. Due to its special structure and location, maxillary sinus elevation is faced with challenges of bone graft materials, surgical methods and management of complications. Concentrated growth factors （CGF） is the third generation of platelet concentrate with a dense grid structure, which can slowly release growth factors, make the tissue healing process tend to be natural, and effectively promote the regeneration of bone and soft tissues. In recent years, CGF has been adopted in dental implantation with unique advantages, and widely applied in maxillary sinus elevation. In this article, research progresses on CGF in the maxillary sinus augmentation and sinus mucosal repair were reviewed, aiming to provide a reliable theoretical basis for the application of CGF.
