†Two-sample t-test. Employing Bonferroni’s correction for multiplicity, statistical significance was set at (alfa: 0.05/6 = 0.008); FCG: flapless corticotomy group; TCG: traditional corticotomy group; SD: standard deviation; CI: confidence interval; the TCG values were subtracted from the FCG values.
