The comparison of the analysed outcomes was performed by nonparametric Fisher Test for unpaired data according to the number of implants and to the splinting technique. A meta-analysis was performed for the odds ratio (OR) for implant failure between four splinted implants and more than four splinted implants.\n\nResults Twenty-eight studies were included in the systematic review. The survival rate of implants appeared to be higher when at least four implants were placed to support the overdenture, compared to less than four implants. The survival rate of overdentures and the patient satisfaction were not influenced by the number of implants.\n\nThe metanalysis could only be performed to compare the implant survival rate of a four splinted implants group and more than 4 splinted implants group, without significant differences between both groups (OR = 0.39; 95 % CI: 0.14, 1.14; p = 0.09).\n\nConclusions Although the placement of at least four implants to support a maxillary overdenture seems to report higher implant survival rates, further studies are needed to confirm this conclusion. No differences were found for overdenture survival rates or patient satisfaction according to the number of implants.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Authors Guenin C., Mart\u00edn-Cabezas R.
