The authors report their experience on 15 cases, including reconstructive surgery of the jaws, postextraction alveolar bone regeneration, and oral implantology. The aim of the study was to evaluate the different effects on jaws' bone regeneration with or without the use of local application of platelet-rich plasma (PRP). The results we report showed the efficacy of the PRP treatment: postoperative patients' satisfaction and low-morbidity course confirmed the quality of the results. The article will help the reader to (1) understand the PRP preparation, (2) find local applications in oral and maxillofacial surgery, and (3) evaluate the general effect of PRP.
