Abstract:
A 15-year-old female presented unilateral Class II molar relation with 90% overbite, retroclined upper central incisors, and impacted lower right canine. Nonextraction treatment was planned to correct deep bite, retroclination of upper central incisors, and unilateral Class II molar relation. Intrusion arch was used to intrude and procline the upper central incisors. Correcting the axial inclination of retroclined incisors caused unlocking of the mandible. This, in turn, leads to simultaneous correction of class II molar relation. The vertical loop was used to disimpact canine. Posttreatment incisors inclination was corrected, bilateral Class I molar relation was achieved, and canine had erupted in its position. The smile arc was improved along with mentolabial sulcus and nasolabial angle.

Abstract:
A 10-year-old female presented with a skeletal Class II relation with 7 mm of overjet, 40% overbite, and bilateral posterior lingual crossbite. Two-phase therapy was planned to correct Class II skeletal relation, overjet, overbite, and to achieve lip competency. Phase I therapy was done with twin-block appliance to advance the retrognathic mandible. Phase II therapy was accomplished with fixed appliance for arch coordination to correct minor displacement and to finalize occlusion. Posttreatment, skeletal Class I relation was achieved. Incisors' inclination was improved, and ideal overjet and overbite with bilateral class I molar relationship was achieved. As the mandible advanced, lip competency, facial convexity, and mentolabial sulcus improved.
