Orthodontic camouflage treatment of Class III skeletal malocclusion with severe deep bite and impacted upper canine using preadjusted appliances

Class III skeletal malocclusion in young patients can be corrected by orthodontic camouflage treatment. Many factors should be considered before treatment planning, such as facial appearance, skeletal discrepancy severity, expected future growth pattern, dentoalveolar compensation, and crowding degree. This case report describes orthodontic camouflage treatment administered to a 12-year-old female patient with class III skeletal malocclusion, prognathic mandible, hypodivergent facial type, anterior and posterior crossbite, severe deep bite, and impacted upper canine treated using preadjusted appliances for 17 months. Maxillary incisors were proclined to create space for the upper canine combined with a posterior bite raiser to jump the bite and correct the anterior crossbite. Anterior crossbite correction created space between the maxillary and mandibular occlusal planes, allowing extrusion of the upper and lower molars, which is favorable for deep bite correction. Proclination of the upper anterior teeth created space for the eruption of the impacted canines, and the piggyback technique was used to bring the canines to occlusion. A combination of the reverse curve and class III elastics was also used to achieve better lower incisor inclination. At the end of the orthodontic camouflage treatment, the patient's facial profile was improved with normal overjet and overbite.
