Severe maxillary and mandibular bone atrophy resulting after therapies are usually treated with autologous bone grafting procedures even though these techniques often present a significant risk of postoperative complications and disadvantages. We describe the case of a 59-year-old woman presenting severe bone defect after being treated with surgery and radiotherapy for recurrent oral verrucous squamous cell carcinoma. We performed bone regeneration using Platelet-Derived Growth Factors (PDGF) in combination with autologous bone chips. Our procedure of bone regeneration allowed the placement of dental implants and the achievement of a good aesthetic and functional result. Regenerative surgery may enable the regeneration of substantial bone defects. Moreover, PDGF application decreases the risk of implant failure in irradiated patients.展开更多
