In this case report, a female patient who was 19 years old came to the orthodontic department with pseudo-transposition and torsiversion. Patient has skeletal class III malocclusion and dentally she had super class I on both sides. Her profile was slightly concave with procumbent lower lip. Treatment plan included extraction of carious upper left second premolar and remaining all first premolars. Couple mechanics were applied for the correction of both upper canines which were in torsiversion. The treatment duration was 36 months. Both pseudotransposition and torsiversion were corrected. Proper overjet and overbite was achieved with improvement in the lower lip procumbency.
