ZYGOMATIC IMPLANTS: ADVANCES AND CLINICAL COMPARISONS BETWEEN BRAZIL AND THE UNITED STATES

Zygomatic implants represent a significant advancement in the rehabilitation of patients with severe maxillary atrophy, offering an alternative where conventional implants are not viable. This narrative review explores the historical development, clinical applications, and technological advancements of zygomatic implants, focusing on a comparative analysis between Brazil and the United States. While both countries share a commitment to innovation and patient care, their approaches differ considerably. The United States adopts standardized protocols with strong emphasis on digital planning and regulatory oversight by the FDA. In contrast, Brazil exhibits a more flexible and adaptive approach, prioritizing immediate loading protocols, multidisciplinary collaboration, and broad professional training through postgraduate programs. Technological advances such as high-purity titanium, 3D-printed guides, and bioactive ceramics have contributed to the evolution of implantology in both contexts. The review also addresses complication rates, prevention strategies, and ethical considerations, including informed consent and equitable patient selection. Ultimately, this study highlights the strengths of both systems and emphasizes the value of international collaboration to enhance outcomes and knowledge transfer in implant dentistry. By understanding local adaptations and global trends, practitioners can better tailor treatment strategies and improve the efficacy and safety of zygomatic implant procedures worldwide.
