Table 2.

Average values (computed over the five repetitions of each experiment) and standard deviation of the friction forces measured in experimental campaign EC2 (buccal malalignment). Statistical comparisons (Tukey post hoc test, control group 5: conventional stainless steel bracket) are shown in the last column.
