Conventional implant treatment cannot always be used to rehabilitate edentulous patients with advanced maxillary atrophic. Zygomatic dental implants have been used over the past 20 years as an alternative treatment solution to bone grafting. The purpose of this meta-analysis is to evaluate the implant and prosthetic survival rate in non-oncologic patients with a severely atrophic maxilla. This review also aims to better understand the rate of peri-operative complications in this cohort of patients. A multi-database (PubMed, MEDLINE, EMBASE, and CINAHAL) focused systematic search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. Any randomised control trials studies involving human participants treated with zygomatic osseous implants were included. After eliminating duplicates, a total of 4 studies met the inclusion criteria for this meta-analysis review. With all the studies included there was a total of 174 patients treated with zygomatic osseous implants. The overall implant success rate was 98.03 %. The prosthetic success rate was 96.4 %. The most frequent peri-operative complication was sinusitis. Based on the limited data available in literature, zygomatic dental implants represent a valid alternative to bone augmenting procedure. However, they are not without risks and longer follow-ups are required to confirm the validity of the treatment in long term.
