case_images: No obvious root resorption was found (Fig. 2).
case_images: A specially designed labial and palatal arch appliance. Three cantilevers were welded on the labial and palatal arch separately, which was constructed to facilitate the distal movement of the canine and used as anchorage for forced eruption of the impacted teeth in the upper arch.
