Objectives This randomized controlled trial used resonance frequency analysis ( RFA ) to assess the effects of the presence or absence of a cast rigid bar splinting multiple implants in the stability of immediately loaded implants. Material and Methods Twenty‐nine edentulous patients were randomly divided into two groups: G1 with full‐arch implant‐fixed prostheses and G2 with multiple implant splinting via acrylic resin denture bases. All implants were immediately loaded. RFA measurements assessed implant stability at three different times (T0 – at baseline, T1 – 4 months, and T2 – 8 months. Wilcoxon and Friedman tests and a multivariate model with repeated measures for longitudinal data were used for statistical comparison (α = 0.05). Results Twenty‐nine patients were assessed (G1 = 15 and G2 = 14). Implant and prostheses survival rates were 100% for both groups after the 8‐month observation period and no significant differences in the mean ISQ values were found at the different implant stability assessment times ( P > 0.05). Conclusions The different splinting protocols did not appear to affect implant stability during the 8‐month observation period.
