Management of a hyperdivergent class III malocclusion, maxillary midline diastema, and infected mandibular incisors in a young adult.

摘要

This is a case report of a 20-year-old woman with a hyperdivergent Class III malocclusion, infected mandibular incisors, maxillary midline diastema, and a mild tongue thrust. Extraction of the infected incisors and orthodontic treatment involving partial mesial movement of the remaining mandibular teeth produced a well-intercuspated Class III occlusion. After successful orthodontic treatment, a 4-unit bridge with pontics for the mandibular central incisors completed the rehabilitation and met the functional, esthetic, and occlusal treatment goals. Occlusal stability of the treatment result has been excellent in the 3-year follow-up.
