The upper and lower arch relationship showed class III canines on both sides, anterior crossbite with a reverse overjet of -6 mm, and a bilateral posterior cross bite (Figures 1(a) and 1(b)). Soft tissue analysis revealed the classical appearance of severe class III malocclusion with a retruded upper lip and protruded lower lip (Figure 1(c)). A panoramic radiograph showed condyles that were symmetrical in size and shape without any obvious pathology and missing lower first and third molars (Figure 1(d)).
