Figure 6-e Left lateral intraoral photograph in MIP showing class II molar relationship and retained deciduous canine. Figure 6-f Panoramic x-ray. The upper left canine showing root apex almost formed, but not erupted, due to lack of space. Figure 6-g Lateral cephalogram showing slightly retrusive mandible and protrusive upper incisors. Jarabak’s cephalometric analysis showed a strong counterclockwise growth tendency expressed in such measurements as a posterior facial height-anterior facial height ratio of 70%, a long ramus height in comparison to the posterior cranial base length, and a small Y-axis-to-SN angle (Table 1). 60 Linton, Jung | The Effect of Tooth Wear on Postorthodontic Pain Patients: Part 2 Table 1 Jarabak’s analysis of case 6 in January 2000. The maxillary arch was rapidly expanded with a fixed- type expander, which was retained for 6 months. Growth modification of the maxillary protrusion was accomplished simultaneously with a high-pull headgear for 10 months. The diagnostic study models mounted before and after headgear therapy clearly showed the effect of the growth modification treatment (Figure 7). Figure 7 Mounted models of the case before and after the first phase of growth modification treatment. The models were mounted on a semiadjustable articulator with estimated face-bow transfer and with centric relation bite registration records. The class II relationship of the first molars (blue lines) in January 2001, was improved compared to the molar relationship of the case in January 2000. Subsequent to headgear therapy, the four first premolars were extracted, and the patient received fixed-appliance therapy for the following 20 months. Class I canine and molar relationships were achieved with maximum anchorage in the upper arch and moderate anchorage in the lower arch in December 2002. The patient’s facial appearance was
improved, with retraction of the upper anterior teeth and favorable mandibular growth (Figure 8). Figure 8-a Front facial smiling photograph. Figure 8 Postorthodontic treatment records. Figure 8-b Lateral facial photograph showing improvement in profile compared to Figure 1b. Figure 8-c Right lateral intraoral photograph showing that class I canine and molar relationships were achieved. Figure 8-d Front intraoral photograph showing that approximately 2 mm of overjet was achieved. Figure 8-e Left lateral intraoral photograph showing that class I canine and molar relationships were achieved. Figure 8-f Maxillary arch showing alignment without any extraction spaces left.
