Superimposition of the cephalogram tracing and transition of TV, OCC, and TV/OCC ratio. a Group I representative—Subject M.K. (female; 35 years, 2 months). Superimposition of cephalogram tracing between T0 (solid line) and T1 (dotted line). The value of the change of TV/OCC ratio from T0 to T1 and from T1 to T3 was small, and the transition of TV/OCC ratio was stable during all the experiment period. b Group II representative—U.M. (female; 25 years, 6 months). Superimposition of cephalogram tracing between T0 (solid line) and T1 (dotted line). Although the value of the change of TV/OCC ratio from T0 to T1 increased, the value from T1 to T3 got closer to TV/OCC ratio value at T0. c Group III representative—subject E.U. (male; 26 years, 8 months). Superimposition of cephalogram tracing between T0 (solid line) and T1 (dotted line). Although the value of the change of TV/OCC ratio from T0 to T1 decreased, the value of TV/OCC ratio form T1 to T3 got closer to TV/OCC ratio value at T0
