Recombinant human bone morphogenetic protein-2 (rhBMP-2) is an osteoinductive protein approved for use in oral and maxillofacial defect reconstruction. Growth factors act as mediators of cellular growth on morphogenesis and mythogenesis phases. Utilized as recombinant proteins, these growth factors need the presence of local target cells capable of obtaining the required results. This cell population may be present at the wound site or added to scaffolding material before implantation at the surgical site.
The aim of this study is to evaluate the clinical and radiographic results of a reported case with a large bone defect, treated with an absorbable collagen sponge, rhBMP-2 and a titanium plate and mesh. The Authors want to report a case which shows the resulting effectiveness of the rhBMP2 action regarding a large, mandibular defect reconstruction. This case also shows how the removal of a rare tumor such as a ghost cell tumor of the jaw may be treated without harvesting bone from another body site. A quick diagnosis of the lesions is important in order to perform the most suitable treatment. The Authors also underline the clinical and histological steps to insure the correct treatment is carried out to solve the case.
Moreover, from results obtained from this case, it is possible to highlight several clinical benefits for the patient by adding rhBMP-2 to the common allograft to not only have alveolar reconstruction defects and sinus floor augmentation, but also to have alveolar cleft reconstruction and to treat segmental defects.
