Comments

The crowding in the upper and lower anterior segments was relieved through staging of interproximal tooth reduction (IPR) in order to avoid unwanted tooth movements. More IPR was prescribed on the upper left quadrant for correction of the upper dental midline by facilitating shifting of the upper midline towards the left. Proper arch form was achieved through mild transverse expansion of the buccal segments. The open bite was closed and the overbite was improved by a combination of intrusion of the upper posterior segments and extrusion of the upper incisors. Light Class II elastics were worn to facilitate coordination between the upper and lower arches.
