Bite closure was achieved through programmed interproximal reduction (IPR) and the retroclination of anterior teeth. At the end of treatment, the open bite was successfully closed, a Class I relationship was obtained on the right side, and an edge-to-edge Class II relationship persisted on the left due to underlying skeletal asymmetry.
