The role of polypeptide growth factors in periodontal regeneration has been documented through animal and human studies. Human platelets contain platelet-derived growth factor (PDGF) and transforming growth factor-beta (TGF-beta) in their alpha granules. PDGF has been shown to play a role in periodontal regeneration. It has been demonstrated that TGF-beta has a very potent effect on cells associated with bone. The case reports presented demonstrate a new biotechnology in which platelet gel is used in combination with demineralized freeze-dried bone allografts for the treatment of periodontal osseous defects. The treated teeth presented with severe bone loss and a guarded prognosis. Platelet gel biotechnology was used as a novel treatment modality. A significant reduction in probing depths was noted, and radiographically significant amounts of new bone were visible as early as 2 months postoperative. Results up to 2 years postoperative are presented.
