Recovery of anterior torque loss and correction of deep bite occuring during orthodontic treatment with premolar extraction in Class II patients

This paper aimed to offer a way to recover the loss of anterior torque, deepbite, and the deep and reverse curve of Spee that occurred during space closure in skeletal Class II malocclusion. A female patient with a skeletal Class II pattern and the steep mandibular plane was treated with temporary skeletal anchorage devices (TSADs), accentuated and reversed curve nickel-titanium archwires and TSAD-anchored Class II elastics. After treatment, the patient's occlusion significantly improved, and the results were stable at five years posttreatment. The combined use of TSADs and continuous archwires with accentuated and reverse curve could be a reliable and effective treatment modality for torque control and intrusion of retro-clined incisors and leveling of the curve of Spee.
