Patients were randomly divided into two groups of treatment (MMF) and control (no MMF). In the treatment group, MMF was performed for 2 weeks; meanwhile, MMF was not performed in the control group, and only guiding elastics were applied postoperatively. Lateral cephalograms were obtained preoperatively (T1), immediately after surgery (T2), and at 1 year postoperatively (T3). The distance from points <jats:italic>A<\/jats:italic> and <jats:italic>B<\/jats:italic> to the <jats:italic>X<\/jats:italic> and <jats:italic>Y<\/jats:italic> plane were measured to identify the amount of vertical and horizontal relapse in 1 year as a primary outcome.
