The vertical misfit was evaluated before porcelain application (T1) and before (T2), and after thermomechanical cycling (T3) by stereomicroscopy. Cantilever fracture strength was tested with a 50 kN (5000 kgf) load cell at a crosshead speed of 0.5\u00a0mm\/min. Qualitative and quantitative photoelastic analysis was performed to evaluate stress distribution at seven specific points in five FPDs (<jats:italic>n<\/jats:italic> = 1\/group) subjected to occlusal loading.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Only the molar showed interaction among the three factors (G \u00d7 S \u00d7 T; F<jats:sub>(20.932)<\/jats:sub> = 1.630; <jats:italic>p<\/jats:italic> = 0.044). Thermomechanical cycling (T2 vs. T3) had a significant effect on intra\u2010group vertical misfit in molar, especially in LAS Co\u2010Cr (\u0394 = 5.87; <jats:italic>p<\/jats:italic> = 0.018) and OP Co\u2010Cr (\u0394 = 5.39; <jats:italic>p<\/jats:italic> = 0.007), with no significant effect in premolar (<jats:italic>p<\/jats:italic> &gt; 0.05). Ceramic application combined with thermomechanical cycling (T1 vs. T3) caused a significant intra\u2010group increase in vertical misfit in all groups, both in the molar and premolar (<jats:italic>p<\/jats:italic> &lt; 0.05). OP Co\u2010Cr was associated with greater vertical misfit and stress concentration. Frameworks manufactured by the CAD\u2010CAM system exhibited lower vertical misfit and better stress distribution. FPDs with metal frameworks (&gt;410.83 \u00b1 72.26 N) showed significantly higher fracture strength (<jats:italic>p<\/jats:italic> &lt; 0.05) than zirconia (277.47 \u00b1 39.10 N), and the first signs of ceramic veneering fracture were observed around 900 N.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>FPDs with frameworks manufactured using a CAD\u2010CAM system appear to be associated with lower vertical misfit and better stress distribution, although the section of the frameworks followed by welding may be a viable alternative.
