The inclusion criteria were at least 10 maxillary edentulous patients restored by IOD or IFR and at least five years of follow up. RoB 2, and NOS tools were used to assess risk of bias. Implant survival rate (ISR) was calculated as primary outcome. Protheses survival rate, marginal bone loss (MBL), and complications were the secondary outcomes.
