During implant restorative dentistry, common and crippling postoperative complications are pain and swelling of perioral soft tissues which engraving on patient quality of life. Concentrated growth factors (CGF), a novel generation of autologous platelet concentrate, and melatonin, endogenous indoleamine with also bone regenerative properties, may be useful for reconstruction of bony defects as well as in prosthetic and esthetic rehabilitation. We report a clinical case in which guided bone regeneration was performed combining CGF, melatonin and heterologous biomaterial. Great postoperative recovery without any complications was reported. In conclusion, in restorative dentistry the combined use of CGF and melatonin may have important roles in restoring bone defect, in improving implant osteointegration and, not less important, in preventing postoperative complications.
