Two models, one for each group, were printed. Five RPDs were made in each group. In group CR, the framework was milled from a cobalt\u2010chromium alloy. While in group PK, it was milled from a polyetherketoneketone blank. Strain gauge rosettes were bonded distal to the last abutment and posteriorly in the distal end of the residual ridge. Unilateral vertical and oblique loadings were applied. Mann\u2010Whitney U test was used for inter\u2010group comparisons while the Friedman test was used for intra\u2010group comparisons and corrected by Wilcoxon Signed\u2010Rank Sum.
