Figure 3 Teeth movement changes during treatment. A-C: Treatment began with full-mouth direct bonding system and leveling using 0.016-inch × 0.022-inch Ti-Ni alloy wire; D-I: The anterior crossbite was corrected by lower canine distal drive with a closed coil spring and anterior retraction with a power chain; J-L: Class III intermaxillary elastics were used to achieve normal overbite and overjet by the 20 months.
