Abstract

A wide range of skeletal and dental configurations can result in Class II malocclusion. For the correction of skeletal Class II malocclusions, a variety of treatment approaches are available, including functional appliances, extraoral appliances, and orthopedic realignment of the jaws surgically depending on the patient’s age and severity of the malocclusion. In this case report, a 13-year-old male patient presented with a ClassII
division 1 malocclusion on a Class II skeletal base with convex profile and posterior divergence and increased incisor visibility. Intraorally, he presented with Angle’s Class II molar relation bilaterally and incisor relation with an overjet of 9 mm and overbite of 4 mm. There were two stages to the treatment. Stage 1 was growth modification with twin-block appliance, and Stage 2 was post-functional orthodontics with pre-adjusted edgewise appliance 0.022” × 0.028” MBT prescription for dental correction and finishing and detailing of occlusion. The posttreatment results were highly satisfactory, showing improvement in facial esthetics with an acceptable occlusion.
