Bone defects around dental implants are considered to be diseases affecting the support and stability of the implant, thus limiting osseointegration. Treatment of these defects involves guided bone regeneration procedures, defined as the reproduction or reconstitution of a part lost or damaged of the peri-implant bone tissue with the purpose of restoring its architecture and function. Platelet-rich plasma and fibrin-rich plasma are autologous platelet concentrates widely used in guided bone regeneration and periodontal regeneration. However, their clinical, histological and radiographic results are debated when bone defects around dental implants are dealt with. The present review included a search for information in the databases of various search engines (PubMed, SciELO, Redalyc and ScienceDirect) to find papers about the use of platelet concentrates (platelet-rich plasma and fibrin-rich plasma) in guided bone regeneration therapy. Clinically, platelet concentrates yield favorable results in reducing probing depth and raising the level of clinical insertion in the treatment of periodontal intraosseous defects. Histologically, platelet concentrates enhance bone neoformation, speeding up regeneration. Radiographically, platelet concentrates lead to an increase in bone density, bone filler and mineralized tissue. A significant reduction is thus achieved in the size of the bone defect.
