Introduction. The resorption and remodeling of alveolar ridge after tooth extraction is a natural, psysiological phenomenon, which might affect irreversibly and negatively the perspective of oral rehabilitation. Different materials have been suggested for augmentation of sockets after tooth extraction.  Aim of the study. The purpose of this study is to compare the regenerative properties of a biomaterial used in extraction sockets as an augmentation technique.  Materials and methods. The study group comprises patients who benefit from the application of platelet-rich fibrin and some of them who do not.   Results. It is proved that regeneration of the sockets can be achieved using a non-expensive method of augmentation and prevent the reduction of bone size in future oral rehabilitation.  Conclusions. The benefits of using platelet-rich fibrin are to stimulate bone regeneration, increase osteogenesis and to deal with postextractional complications.
