Reconstrução de maxila atrófica com enxerto de BMP-2

Abstract

The loss of bone structure of the jaws with the implementation of the main challenges of implantology, especially in the anterior region of maxilla. Because of this bone loss, the bone graft is indicated as part of the rehabilitative treatment. In the literature, the autogenous bone is the gold standard for bone reconstruction. Recombinant human proteins (rhBMP-2) are one of the options for autogenous grafts, due to their highly osteoinductive biomaterial characteristics. This paper reports the case of a female patient, 45 years old who had previous maxillary atrophy. After clinical and radiographic examinations, it was necessary to reconstruct bone for oral rehabilitation through osseointegrable implants. RhBMP-2 associated with collagen sponge (Infuse Bone Graft) and Bio-oss were used as the osteoconductor. Ten months after the reconstruction surgery, a new computed tomography was performed and presented a bone gain of significant thickness, being possible the planning for rehabilitation with osseointegrable implants.
