CASE REPORT “My hope was the light force placed on the upper anterior teeth would have more of an effect on tooth C and less of an effect on D through H.” Fig. 5 Fig. 4 My hope was the light force placed on the upper anterior teeth would have more of an effect on tooth C and less of an effect on D through H. I saw Katy every three weeks and simply placed an additional bead to keep a light advancement force. The total treatment time was nine weeks. Once the interference was corrected, the crossbite and shift was also corrected (Fig. 4). 14 November/December 2010 JAOS The correction was self-retentive (Fig. 5). I was pleas-antly surprised how easy the correction of this crossbite was and how well Katy tolerated the treatment. The crossbite left untreated could have lead to a much more difficult malocclusion in the future. The final extra oral photo shows that a better facial symmetry has been produced.
