The aim of this research paper is to investigate the electromyographic behavior of the elevator, masseter and temporal muscles, during the orthodontic treatment with aligners (F22). The subjects were 8 healthy adult patients between 20-40 years of age. EMG carried out at the beginning of the therapy (T0) and after each month (T1, T2, T3) with and without aligners (F22). In the statistical analysis, for each measure, a repeated measures ANOVA with post-hoc tests was used. The post-hoc tests show that the impact of the appliance is significant only at time T0. After an initial elevation, a subsequent lowering of the electromyographic values of the muscles Masseter and Temporal in patients wearing aligners (with F22 systematics) could suggest an adaptation of the entire stomatognathic system.<\/p>\n","protected":false},"template":"","meta":{"_acf_changed":false},"categories":[2640],"tags":[2857,2922,2923,2921],"affiliation":[],"contributor":[3072,3073],"journalissue":[3138],"class_list":["post-23866","article","type-article","status-publish","hentry","category-ann-stomatol-2023-vol-31-january-april","tag-clear-aligners","tag-electromyography","tag-emg","tag-f22","contributor-a-fantauzzo","contributor-g-kussini","journalissue-ann-stomatol-2023-vol-31-january-april"],"acf":[],"yoast_head":"\n
