Fig. 7. The treatment sequence for uprighting of the left mandibular first molar (the blue arrow indicated) (15M; 15 months after orthodontic treatment started). Progress is shown at treatment times in months. The archwire was 0.017 × 0.022-inch (in) Elgiloy and a 0.016 × 0.022-in stainless steel cantilever was used for uprighting the left mandibular first molar. At 21 months, a molar tube was bonded on the buccal surface of the first molar and the 0.018-in nickel-titanium archwire was engaged for its alignment.
