Rehabilitation of atrophic maxilla with double zygomatic implants: clinical case report

Abstract

The rehabilitation of patients with severe maxillary bone atrophy presents significant challenges due to the anatomical characteristics of the maxilla and the limitations of conventional implant techniques. Progressive bone resorption, associated with pneumatization of the maxillary sinus, often makes the use of conventional dental implants unfeasible, due to insufficient bone height and thickness for their installation. Bone grafting techniques have been used as a solution, but involve greater surgical morbidity, high costs and prolonged rehabilitation times. In this context, zygomatic implants emerge as an effective alternative for treating severely atrophic maxillas. This technique, which requires in-depth knowledge of anatomy and biomechanical considerations, allows anchorage in the zygomatic region, reducing morbidity and accelerating the rehabilitation process. Although some surgeons are still hesitant to adopt this approach due to controversies regarding its feasibility, studies have shown that its success rates are comparable to those of conventional implants. The benefits of zygomatic implants are clear, especially in cases of major resorption of the alveolar process and exacerbated pneumatization of the maxillary sinus. They reduce the need for extensive bone grafting, hospitalizations, and associated complications, providing a faster and more efficient solution for the rehabilitation of patients with severe maxillary atrophy.
