Abstract
Introduction: Severe maxillary atrophy represents a burden on aesthetic recovery in patients with trauma and tooth loss. Treatment planning for guided prosthetic rehabilitation of the maxilla with Zygomatic Implant (ZI) can be performed digitally. The surgical and prosthetic plan, position, emergence, implant shape, temporary prosthesis position, interarch relationships, and surgical templates can be designed in a fully virtual environment. Objective: The purpose was to present the clinical results of a systematic review demonstrating the importance of zygomatic implants by guided surgery in bone elevation loss. Methods: The PRISMA Platform systematic review rules were followed. The search was carried out from November 2024 to January 2025 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. 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: 111 articles were found, 25 were evaluated in full and 15 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 25 studies with a high risk of bias and 31 studies that did not meet GRADE. Most studies did not show homogeneity in their results, with X2=78.5%>50%. It was concluded that the use of virtual tools enables the precision of implant positioning, validating its safety, reliability, and precision of guided surgery for the placement of zygomatic implants. The use of specialized implant planning software is an important tool to achieve predictable results for zygomatic implants and allows a good visualization of the implant-anatomical structures relationship.
