The patient has complained of UR1 turning (mesial incisal edge elongation due to bracket off placement) since the 1st appointment post banding. On the 3rd appointment (2 months 12 days post banding with 18 ss wire), the mesial incisal edge of UR1 and the distal incisal edge of UR3 are trimmed; 18 wires are reused with addition of an open coil spring between UR1-3 (Fig.7). Extra diastemata have appeared mesial and distal to UL1 (Fig.8 *), creating room to correct the upper dental midline shifting.
