CASE STUDY “In month eleven, I made sectionals from the .018 x .025 stainless steel arch wire previously used, replaced back into the upper and lower arches, instructing the patient to wear cross arch quarter medium elastics to fully intercuspate the premolars. The patient wore these sectionals for one month.” second molars had erupted partially enough and buccal tubes were placed on the second molars and an .018 Nitinol arch wire was placed in both the upper and lower arch for approximately one month. Following alignment of the second molars, I replaced the .018 Nitinol upper and lower arch wire with a .016 x .022 stainless steel arch wire. Class II elastics were then increased to two quarter medium elastics during the day and two at night. Following Class II correction of the molars and canines, a .018 x .025 stainless steel arch wire was placed for two months to stabilize the periodontal ligaments prior to removal. In month eleven, I made section-als from the .018 x .025 stainless steel arch wire previously used, replaced back into the upper and lower arches, instructing the patient to wear cross arch quarter medium elastics to fully intercuspate the premolars. The patient wore these sectionals for one month. Fig. 9 In month twelve, posterior bands and brackets were removed, final records were taken, (Fig. 6) and a lower bonded 3-3 as well as an upper Essix retainer were placed. (Fig. 7). Final cephalomet-ric radiograph (Fig. 8) and panoramic radiograph Fig. 9) were taken and the final analysis was performed (Fig. 10). Although the upper left 7 molar slipped slightly buccal due to band failure on the adjacent 6. I was satisfied with the results of the case as was the Fig. 10 www.orthodontics.com Summer 2019 25
