Treatment of mandibular deviation with the replacement of upper laterals with central incisors - a case report

ABSTRACT

Premature contact of teeth in posterior crossbite may be associated with facial asymmetry. To describe the surgical treatment of mandibular deviation associated with a marked facial asymmetry, and build up the two upper lateral incisors in place of the two upper central incisors. A 20 year-old boy with a unilateral posterior crossbite, noticeable facial asymmetry, and anterior crossbite is presented. He had a history of head injury in mixed dentition period. The upper central incisors were lost during trauma and the created space was replaced by the two upper lateral incisors. A removable appliance was used to correct the crossbite and it was followed by fixed appliances. Orthognathic surgery was done to complete the treatment. After that the two upper lateral incisors were built up and reshaped. Treatment resulted in a marked improvement in facial symmetry, elimination of the mandibular displacement and a stable occlusion. A patient with mandibular deviation and marked facial asymmetry was successfully treated surgically and two upper lateral incisors were built up and reshaped in place of the two upper central incisors
