The severe individual rotation is a kind of malposition of tooth that interferes with smile esthetics and may cause occlusal interferences.
A 13-year-old girl with 90° rotation of the right central maxillary incisor and lack of space was referred to Faculty of Dentistry, Hamadan University of Medical Sciences, Hamadan, Iran. Firstly, a spring-designed appliance was used between the left central and right lateral incisors to make enough space. Thereafter, a fixed orthodontic appliance was utilized to correct the rotation of the tooth.
