case_images: T-loop was designed to upright the lower-left second molar tooth (Figures 2(a)-2(b)). The uprighting force was transferred to the teeth by a bonded button on the occlusal surface of the lower second molar tooth (Figures 3(a)-3(c)).
case_images: Clinical view after applying appliance: (a) frontal view, (b) left view, and (c) occlusal view.
