Orthotown.com > Message Boards > Clinical Topic > Clinical Orthodontics > Phase 1: Anterior Crossbite and Crowding Fenrisúlfr Member Since: 02/25/09 Post: 1 of 33 Introduction Thought I'd share this recently completed Phase 1 case. A 10-year-old patient, mildly mid-face deficient, pre-menarche, presented with an anterior crossbite U2-2 and with 6-8mm of crowding. There was a CR-CO slide. Treatment plan included RPE + 2x2 to advance and extrude the upper 1s, followed by sequential alignment of the 2s (once the 3s have cleared the roots). Although there were facemask hooks, I did not use a facemask. Retention is with a modified Theroux retainer.
