Brief Summary

The platelet-rich fibrin (PRF), belongs to a new generation of plasma concentrate with biomechanical processing simplified and without the need for handling blood biochemistry. Some studies have shown the potential of PRF in release growth factors assisting and accelerating the regeneration of soft tissues, however with contradictory results regarding the hard tissues. The aim of this study will be to evaluate through clinical analyzes, histomorphometric and micro-computed tomographic images, the dimensional changes, the quantity and the quality of the tissues formed socket after extractions that receive membranes of PRF. 15 sockets (test group) will receive a membrane of PRF after extraction and the other 15 (control group) received no biomaterial (spontaneous healing).
