Treatment Strategy for Dental Malocclusion of Angle Class II Division 2 with Crowding and Deep Bite: A Case Report

Abstract

Malocclusion is the most common oral health problem after caries and periodontal disease, affecting over half the global population. Treating Angle Class II Division 2 malocclusion is difficult because of the risk of unwanted incisor flaring during levelling and aligning. This case report focuses on biomechanical strategies for managing Angle Class II division 2 malocclusion. A 39-year-old woman had crowding in both upper and lower teeth. Examination showed a class II molar relationship, a 5 mm overbite, and a 1 mm overjet. Treatment involved a fixed appliance and extraction of tooth #24. At the start of levelling, the maxillary incisors were bypassed to reduce flaring, and laceback mechanics were used to create space. This approach corrected the crowding and deep bite condition. Good orthodontic treatment improves both the function and appearance of the teeth and face, and also helps psychological well-being and confidence. This case supports SDG 3 on Good Health and Well-being by improving oral health and quality of life. Treatment strategy included tooth extraction, followed by incisor bypass and laceback mechanics during the initial of leveling and aligning phase, with subsequent incisally bracket placement of incisors, facilitating crowding and deep bite correction, controlled incisor inclination, and achieving functional and good occlusion in Angle class II division 2 malocclusion.
