The main objective of our research was to evaluate the PRF potential in bone regeneration of the periodontal bone defect. Using platelet gel for improving bone regeneration is a recent technique in oral surgery and implantology. In this study, based on casuistry, we have evaluated PRF’s local effect combined with the autogenous graft and freeze-dried bone allograft in order to improve bone regeneration in periodontal bone deficiency.

The personal study was accomplished on 5 subjects with various sized periodontal bone deficiencies. From the treated lot, we have selected the most significant clinical case, having an important bone defect in the maxillary frontal area. In the treatment lot we have resolved 3 clinical cases where we have applied peri implantary a mixture of synthetic bone and PRF, plus PRF superjacent membranes. We accomplished a sealing and colonization of the bone defect with the most biocompatible material, assuring quick local bone regeneration and healing. The mixture of PRF – autogenous bone and membrane (PRF), were also used to augment the sinus floor needed for the procedure of elevating the maxillary sinus.
