*2.5. Statistical Analysis*

The descriptive statistics were reported as means ± standard deviation and medians with minimum and maximum values for all variables for each dental-material group. The one-way ANOVA procedure was used to test if there was a difference in total time

and average load among the treatment groups [43]. Post hoc tests were performed using Tukey's adjustment for multiple comparisons. The Games–Howell test was used for multiple comparisons instead of Tukey's test if the assumption of equal variances was not assumed.

The independent-sample Mann–Whitney U test with Bonferroni adjustment was used to compare the medians of the displacement scores of each group with the gold-standard control group. Statistical analyses were performed using IBM SPSS Statistics (Version 25; IBM Corporation 1989, 2018. IBM Corp., Armonk, NY, USA).
