Abstract

To coordinate the dental midlines with facial midline is one of the orthodontic treatment goals. This case report presented a case with Class II dentition crowding and asymmetry by non-extraction therapy with the aids of TADs. Transpalatal arch with extension arm was used to correct buccal version of upper second molar which contributed the mandibular deviation. Molar distalization and arch widening were achieved by using TADs. Midline and Class II elastics resulted more correction of dental midlines to facial midlines. At the end of treatment, Class I canine and molar relationships and centered midlines were obtained. Better facial symmetry was also achieved.
