Fixed rehabilitation in partially toothless patients with severe bone atrophy represents a complex clinical challenge, both in the surgical and prosthetic fields. In the present case, a three-dimensional reconstruction of the atrophic maxilla was carried out using autologous bone grafts obtained in the intraoral cavity. The approach was carried out under a sequential protocol that integrated the use of biocompatible materials, such as resorbable collagen membranes, and then the placement of implants next to Multi Fix pillars.
