Different superscript letters indicate significant difference on each loading point in each strain gauge (P < 0.05).
Positive and negative values of the measured data indicate tensile and compressive strain, respectively.
FC: composite resin core with prefabricated fiver post, ZC: composite resin core with a prefabricated zirconia tube, ZFC: composite resin core with a prefabricated zirconia tube and prefabricated fiver post.
