Lip prominence was reduced by 2.3 and 3.5 mm in the upper and lower lips, respectively, after full-arch distalization (Figure 9).
Changes in the arch form and tooth position following treatment. Axial cuts were made at the mid-crown level and midroot level before and after treatment. Black, initial; white, final.

The position of both the condyles was maintained throughout the treatment (Figure 12).
Changes in the central incisors and the surrounding alveolar housing. Mild root blunting is noted, but the incisors are within their biological boundaries after treatment.
