Introduction: In the context of implantology and severe resorption, zygomatic implants (ZI) are indicated and the procedures can be completed with the placement of a custom-made provisional prosthesis, reducing surgical time and optimizing results. Digital (virtual) optimizations for the ZI were developed in computerized radiology machines that allowed improvements in diagnostic and therapeutic tools. Objective: It was carried out a systematic review of the main considerations and clinical outcomes of using digital tools for the optimization of the virtual zygomatic implant. Methods: The rules of the Systematic Review-PRISMA Platform were followed. The research was carried out from January 2022 to April 2022 and developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 94 articles were found. In total, 62 articles were fully evaluated and 41 were included and evaluated in this study, and of the total of 41 articles, only 14 articles were developed as the main clinical results of the virtual zygomatic implant. Reducing errors and complications is essential if zygomatic implants are to remain a viable treatment alternative, and further research on a guided approach to their placement is encouraged. The surgical guide system showed accuracy for all variables studied and allowed acceptable and accurate implant placement, regardless of the complexity of the case. Thus, the surgical and prosthetic plan, the position, the emergence, the shape of the implants, the position of the provisional prosthesis, the inter-arch relationships, and the surgical templates were designed in a virtual environment and previously performed by the surgeon in stereolithographic models, allowing the surgical procedure was significantly simplified.
