Abstract (English): Rehabilitation of severely atrophic maxillae with zygomatic implants (ZI) has consolidated as a graft-free option for fixed prostheses. This study conducted an integrative review (2020-2025) in PubMed, SciELO and BVS including studies reporting indications, surgical technique/prosthetic protocol, implant survival/success rates and complications, analyzing systematic reviews, meta-analyses, consensus statements, protocols and observational studies. Seventeen publications were synthesized. ZI survival ranged from 92% to 100%, averaging 96-98%, particularly under immediate loading. Sinusitis was the most frequent complication, followed by soft-tissue events and peri-implantitis; these outcomes occurred predominantly in intrasinus approaches. Anatomyguided/extrasinus variants (e.g., ZAGA) maintained high survival and showed lower sinus morbidity, while favoring a more appropriate prosthetic emergence. The most consistent indications encompassed severe maxillary atrophy, previous graft/implant failure, patient refusal of grafting, trauma/ablative defects and cleft conditions. Patient-reported outcomes were positive, with improvements in mastication, aesthetics and quality of life. We conclude that ZI are a predictable and safe option when applied with careful case selection, three-dimensional planning and execution by experienced teams, with postoperative surveillance recommended to mitigate complications.

Abstract (Portuguese): A reabilitação de maxilas severamente atróficas com implantes zigomáticos (IZ) tem se consolidado como alternativa livre de enxertos para próteses sobre implantes. Este estudo realizou uma revisão integrativa (2020-2025) nas bases PubMed, SciELO e BVS que reportaram indicações, técnica cirúrgica/protocolo protético, taxa de sobrevivência/sucesso e complicações, analisando estudos do tipo revisões sistemáticas, metaanálises, consensos, protocolos e estudos observacionais. Dezessete publicações compuseram a síntese. As taxas de sobrevivência dos IZ variaram de 92% a 100%, com médias próximas de 96-98%, especialmente sob carga imediata. A sinusite foi a complicação mais frequente, seguida por eventos em tecidos moles e peri-implantites; esses desfechos ocorreram predominantemente em abordagens intrasinusais. Variações anatômicas/extrasinuais, exemplo da classificação ZAGA - Zygomatic Anatomy Guided-Approach ou em português Abordagem Guiada pela Anatomia Zigomática mantiveram sobrevida elevada e mostraram menor morbidade sinusal, além de favorecerem emergência do implante mais adequado. As indicações mais consistentes abrangeram atrofia maxilar severa, falhas prévias de enxertos/implantes, recusa a enxerto, defeitos por trauma/ressecções e fissuras. Os desfechos relatados pelos pacientes foram positivos, com ganhos em mastigação, estética e qualidade de vida. Conclui-se que os IZ são opção previsível e segura quando há indicação criteriosa, planejamento tridimensional e execução por equipe experiente, recomendando-se vigilância pós-operatória para mitigação de complicações.
