Following data collection reported complications were grouped based on their origin as infectious\/ non\u2010infectious biological and mechanical. Statistical analysis was performed to identify risk factors and preceding complications leading to implant loss (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The survival rate of ZI was found to be 89.9% and the average time between implant placement and an eventual loss was 4.8\u2009years. The mean ZI follow\u2010up period was 7.9\u2009\u00b1\u20094.9\u2009years. Amongst the infectious biological complications, sinusitis was the most reported (<jats:italic>n<\/jats:italic>\u00a0=\u00a0138) occurring at a mean follow\u2010up time\u2010point of 4.5\u2009years, whereas infraorbital nerve hypoesthesia occurred more frequently in the non\u2010infectious biological category (<jats:italic>n<\/jats:italic>\u00a0=\u00a08, meantime: 0.3\u2009years). The prosthetic screw fracture was the most reported complication of mechanical origin (<jats:italic>n<\/jats:italic>\u00a0=\u00a029, meantime: 4\u2009years). Furthermore, sinusitis, standard implant loss, zygomatic\/peri\u2010zygomatic region infection, and oroantral communication were significantly associated with ZI loss.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>ZI placement offered a high survival rate for the rehabilitation of severely atrophied maxilla with most losses occurring within the first 5\u2009years at follow\u2010up.
