Orthodontic Marvel: Correction of Class II Malocclusion with the Churro Jumper Appliance

Abstract

Class II malocclusion is a common orthodontic issue characterised by an excessive overjet, where the upper front teeth are significantly ahead of the lower ones. It often leads to aesthetic concerns and functional problems. Orthodontic treatment is the preferred solution to correct Class II malocclusion, and among the diverse range of appliances available, the Churro Jumper Appliance has emerged as a groundbreaking innovation. The present case report is about a 15-year-old male patient with Class II division 1 malocclusion and a retrognathic mandible. The MBT 0.022" prescription was used for bonding. After levelling and aligning both the upper and lower arches, and closing the anterior spacing, the Churro Jumper was used as a fixed functional appliance for mandibular repositioning. The required results were achieved using the appliance, and the patient’s occlusion was brought to a Class I molar and canine relationship, while also improving the profile. The treatment was completed in 17 months. Although several fixed functional appliances are available in the market for Class II correction, the Churro Jumper appliance was used in the present case.
