A new torquing method for anterior tooth inclination control: a clinical report with a 7-year follow-up

Appropriate orthodontic mechanotherapy, particularly in relation to incisor inclination control is a key consideration for successful treatment and the delivery of optimal aesthetics. A novel, easy, safe and effective torquing technique, termed Park’s cervical torque tie, has been devised. A female patient sought orthodontic treatment and presented with a Class II division 2 malocclusion with crowding but a favourable facial profile. The treatment plan involved the distal movement of the maxillary posterior teeth, decrowding and incisor inclination correction. Palatal root movement was applied to the retroclined upper incisors by a novel cervical torque tie. The treatment was successfully completed after the distalisation of the dentition and palatal root movement of the upper incisors. However, following post-treatment cone-beam computed tomography, less bone coverage was evident on the palatal surface of the upper incisors. After a seven year follow-up, the treatment results were well maintained, and cortical bone regeneration was confirmed.
