CASE STUDY #2 By Randy K. Newby, DDS SASSOUNI+ CASE STUDY I Figure 1 n the first article 7 in this series the planes and arcs used in the Sassouni + Archial Analysis were identified and described. In the second 8 and third 9 articles in this series the 14 points used in the Cephalomet-ric Bottom Line 3 were described. The Bottom Line allows the practitioner to diagnose an orthodontic case both dental and skeletally and then to treat-ment plan the case. In the fourth article of the series 10 a simple orthodontic case was presented. I showed how I used the individual points of the Sassouni + Bottom Line 3 to diagnose and treat-ment plan the case. In this article a more complex orthodontic case will be presented. The patient’s orthodontic records are shown in figures 1-10. The Cephalometric Bottom Line is shown in figure 8.
