Key clinical considerations and updates on the techniques for successful zygomatic implant: a systematic review

Abstract

Introduction: In the context of implant dentistry, what represents a great burden in the aesthetic recovery of patients who have suffered dentoalveolar trauma is the lack of bone in the alveolar crest, compromising the quality of life due to tooth loss. Objective: Performed a systematic review to present key clinical considerations and updates on the best techniques for successful zygomatic implantation. Methods:The systematic review rules of the PRISMA Platform were followed. The research was carried out from February to May 2023 in 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:A total of 128 articles were found, 54 articles were evaluated in full and 34 were included and developed in this systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 22 studies with a high risk of bias and 32 studies that did not meet GRADE. Zygomatic implants can be placed with good precision. The application of these newly designed 3D-printed surgical guides results in the predictable placement of zygomatic implants and offers the possibility of immediate prosthetic rehabilitation. Preliminary data from one year after loading suggest that immediately loaded zygomatic implants were associated with statistically significantly fewer prosthetic failures. Also, zygomatic implants proved to be a better rehabilitation modality for severely atrophic jaws.
