Facial images showed symmetry between maxillary and mandibular lips and arches. Her face was transverse thin giving a dolichocephalic frontal appearance. Maxillary arch had a U-shaped form with adequate space for eruption of #11. Mandibular arch showed teeth L, S, T still in mouth. #20 was erupting with rotation. Molars and canines present were in Class I, and her midlines matched her face. Fig. 24 One year after removal of all appliances and treatment. Midlines were even with face and primary canines were in Class I relationship. Teeth #7 and #26 were in crossbite. Tongue depressor therapy was implemented to correct this single tooth crossbite. This crossbite correction was accomplished in one-month’ time and followed up for the next three months. Fig. 25 www.orthodontics.com Spring 2021 29
