Orthodontic management in an adult patient with a class II division 1 malocclusion using T-loop: A case report

Abstract

The most common type of malocclusion encountered in India is a Class II div I malocclusion. They are distinguished by a mild to severe Class II skeletal base with an Angle’s Class II molar relation and Class II canine and incisor relations, proclined maxillary incisors, and an increased overjet, as well as a convex profile with incompetent lips. For the treatment of Class II div 1 malocclusion, various treatment modalities have been presented. This case study features a 15-year-old female with a Class II division 1 malocclusion, an orthognathic maxilla, and an 8mm overjet. Treatment goals included achieving functionally optimal and aesthetically acceptable occlusion, eliminating dental arch crowding, reducing overjet, and achieving competency of lips and a balanced soft tissue profile. The treatment plan called for extraction of the upper first and lower second premolars, followed by space closure with a T-loop. Following treatment, a satisfactory result was obtained with an ideal, static, and functional occlusion, facial profile, smile and lip competence, and treatment result stability.
