These were statistically significant (P &lt; .05). With regard to the Peer Assessment Rating score assessing the occlusal improvement, 97.6% showed an improvement whereas only 2 patients showed no improvement. There was a significant improvement in sella (S), nasion (N), and point A (SNA) angle; point A, the nasion, and point B (ANB) angle; and the maxillary length over the treatment period (P &lt; .05). The change in the ANB angle and maxillary length significantly differed between genders with males having a comparatively higher improvement.
