Fig. 48 Fig. 49 Fig. 50 intruding and torquing the maxillary incisors (i.e., getting them out of the way), the mandible grew and sponta-neously advanced forward to a Class I platform (Figs. 41 & 43). To observe skeletal changes in a case, overlay pretreatment and post treatment cephalometric images on the S-N line (Fig. 44). 10 To observe incisor and molar changes in the maxilla, overlay pretreatment and post treatment cephalometric images on the ANS-PNS line (Fig. 45). 10 Facial and orthopedic changes occur-ring in this patient over time are chronicled (Fig. 43). Ideal facial proportions for this patient were obtained at the conclusion of treat-ment (Fig. 42). 7 Fig. 51 Palatal TAD Anchored Appliances The horseshoe jet (Fig. 46-A), Mesial-Distalslider (Fig. 46-B), and Newby/Anderson distalizer (Fig. 46-C) are palatal TAD retained distalizing appliances. 8 They distal drive maxil-lary posterior teeth bodily through the COR (Fig. 47). These appliances and their use will be discussed in 30 Fall 2015 JAOS
