Class III Camouflage Orthodontic Treatment in Adult Patient with Anterior Crossbite and Abnormal Functional Shift: A Case Report

Skeletal Class III malocclusion is a complex malformation with a prevalence of 81.6% in Airlangga University Dental Hospital, distributed in patients aged 15-45 years old. Camouflage treatment of skeletal Class III malocclusion improves prognosis with a mild-to-moderate shift. This study aimed to discuss orthodontic camouflage as an option for adult patients with Class III malocclusion, emphasizing its indications, implications, and expected results. This report presents the case of a 17-year-old male patient with poor facial aesthetics associated with protruded chin, abnormal functional shift, and temporomandibular joint pain. The facial profile was concave with lower anterior multiple diastemas, mandibular lip protrusion, mandibular displacement, and anterior crossbite. This case was treated by camouflage therapy using straight wire appliance system combined with elastic class III. After 24 months of treatment during the pandemic, the mandibular displacement and the crossbite were corrected, the teeth were arched, the anterior crossbite fixed, and the profile became convex. Camouflage orthodontic treatment can be an effective management option to achieve functional occlusion, stability, and a satisfactory aesthetic impression in adult patients with mild to moderate skeletal Class III deformities, anterior cross bite, and functional shift.
