Patients with severe atrophic maxillas are a challenging for oral rehabilitation using dental implants. There are some surgical options in those cases, like zigomatic implants and use of extra-bucal donor sites for bone grafting for posterior implants placement, such as iliac bone, tibia and calvarial bone. Our purpose is to present a follow up clinical study of 10 years accompanying 30 patients (24 female, 06 male), who submitted to reconstructive surgery of the atrophic maxilla with calvarial bone grafting to posterior dental implants installation. In the female group, 45 dental implants were installed in maxilla after the bone grafting healing period and in the male group, 37 dental implants were installed, with a total of 82 implants. Of those 82 implants, 04 were losted in the female group and 01 was losted in the male one. The surgical technic with a different approach to remove calvarial bone, and complications of this procedure are also presented.
