Os desafios da reconstrução de maxila atrófica com enxerto autógeno de calota craniana: relato de caso

Abstract

ABSTRACT Bone reconstruction techniques for atrophic maxillaries have been improved in order to promote bone tissue augmentation in both height and thickness, allowing the installation of dental implants in the proper position. The first consideration in surgical planning to reestablish the bone architecture required for implantation is to determine the nature of the graft to be performed, this choice should be based on the amount of bone needed, available techniques, and patient conditions. As the gold standard, autogenous grafts are the first choice for grafting. Skull grafts are associated with low rates of reabsorption and rejection, and few postoperative complications. The objective of this study was to report a case of bone grafting using bone skull in a patient with severe maxillary atrophy, where bilateral maxillary sinus augmentation was associated with a total restoration of height and width of bony edges for posterior rehabilitation. No trans and postoperative complications were observed, corroborating with the findings in the literature to prove clinical safety of cranial calotte grafts, thus representing a good choice in the reconstruction of atrophic maxillaries.
