Orthodontic Correction of Severe Class III Malocclusion with Deep Anterior Crossbite: A Case Report

Skeletal class III malocclusion has the lowest prevalence in the world, but increases in Asian countries and needs more care for orthodontists to treat. Mandible prognathism, maxillary deficiency and combination of both can be the etiology. So the treatment is very challenging as it varies from dentoalveolar compensation to surgical. To present the case of a 30-year-old woman with skeletal Angle class III malocclusion with deep anterior crossbite, anterior crowding, maxillary midline shifting and a consequent concave facial profile that was corrected with camouflage conventional orthodontic treatment. The camouflage conventional orthodontic treatment is chosen by extracting mandibular premolars. The goal of this treatment is to achieve proper class I occlusion with ideal overjet and overbite, and also to correct every problem existed. After retracting the mandibular anterior segment, good class I occlusion is achieved. The anterior crossbite and soft tissue of lips are corrected in 9 months. And the total treatment was finished within 48 months due to theCorona Virus Disease 19 pandemic periods. Conventional orthodontic treatment as a camouflage treatment is still desired by most patients with skeletal class III malocclusion and it is proven that this treatment is reliable as an alternative conventional treatment.
