Background The purpose of this study was to determine the association between pelvic and center foot pressure (CoP) imbalances and angle class II or III malocclusions. Methods Our study is a prospective, descriptive, and analytic study conducted on two groups: a test group of 53 patients who present malocclusion class II or III compared with 53 controls matched for age and gender. The evaluation of the center of foot pressure (CoP) and the confidence ellipse area (mm2) were performed by stabilometric platefrom using bipodal test in two occlusal conditions, in maximum intercuspation (MI) and with a cotton roll (CR), with and without visual cue. A pelvic level device was used to perform the pelvic balance examination. Statistical analysis used the chi-square test, the McNemar test, and the Pearson test.
