Introduction: Severe maxillary atrophy represents one of the greatest challenges in implant-supported oral rehabilitation, compromising both masticatory function and the patient's quality of life. In these cases, inadequate bone quantity and quality make the placement of conventional implants unfeasible without grafting procedures, which are not always indicated or accepted by the patient. In this context, the zygomatic implant emerges as an effective alternative, anchoring itself in the zygomatic bone—a structure of greater density and volume—and, in most cases, eliminating the need for prior bone reconstruction. Objective: To report the rehabilitative treatment of a patient with Cawood and Howell class IV atrophic maxilla, using zygomatic implants as an implant-supported prosthetic solution, describing the surgical protocol, planning, and results obtained. Case Report: A 58-year-old male patient, completely edentulous in the upper jaw, presented to the clinic reporting masticatory difficulty and dissatisfaction with conventional complete dentures. Computed tomography revealed severe maxillary atrophy, with insufficient bone volume for conventional implants. After virtual planning, three zygomatic implants and one transsinus implant were placed, following the extrasinus technique. The patient progressed without complications. After confirmation of osseointegration, the patient will be re-evaluated in 6 months for the fabrication of the definitive implant-supported prosthesis. Conclusion: The zygomatic implant proved to be a safe, predictable, and effective alternative for the rehabilitation of patients with atrophic maxilla, eliminating the need for bone grafts and reducing the total treatment time. Careful planning and mastery of the surgical technique are fundamental for the success and longevity of the treatment.
