Table 3 Post hoc (Tukey HSD) test results for multiple group comparison showing differences in means and level of significance of these differences between 2 provisional crown materials (milled vs 3D-printed) cemented with 2 different provisional cements (conventional vs resin-modified) using different retentive features (taper, groove, box).
