  1. Data are means ± standard deviation. T0, first use; T1, after 6 months; T2, after 12 months; POC-ATM, percent overlapping coefficient of the anterior temporalis muscles; POC-MM, percent overlapping coefficient of the masseter muscles; %RATM, %LATM, %RMM, %LMM, clench percentages for each muscle; p, significance between appliances (Mann–Whitney test).
