The etiologies of skeletal Class III malocclusion include excessive growth of mandible, deficient growth of maxilla, and the combination of both. Anterior openbite may be due to skeletal, dental, habitual, or functional problems. Mini-implant can be a reliable anchorage for maxillary molar intrusion, which facilitate anterior openbite closure by counterclockwise rotation of the mandible. However, the mandibular counterclockwise rotation may increase antero-posterior jaw discrepancy in Class III malocclusion. Therefore, surgical orthodontics is often required in the treatment of Class III malocclusion with anterior openbite. In this report, we present the treatment of an adult Class III patient with mandibular prognathism, …

Severe root resorption with excessive tooth mobility may compromise the capability of the teeth to sustain occlusal loading, and possibly lead to extraction. Apical external root resorption (AERR) is considered as one of the risks associated with orthodontic treatment. Some clinical factors have been shown to correlate with orthodontic treatment, whereas the determinants for predicting AERR consistently were not found. Therefore, orthodontists must monitor the amount of root resorption during the course of orthodontic treatment. Multiple idiopathic root resorption (MIRR) is a rare condition. If MIRR is present, the severity of tooth mobility may get worsen during orthodontic treatment. The …

Skeletal Class III with anterior open bite is one of the most challenging problems that orthodontists may encounter. Treatment modalities for skeletal openbite malocclusion include growth modification and surgicalorthodontic therapy; which treatment is chosen depends on the patient’s age and growth potential. Treatment considerations should focus on the patient’s facial profile, skeletal pattern, growth potential, and severity of dental malocclusion. Here, we present the nonsurgical orthodontic treatment of an adult patient with anterior openbite and high-angle skeletal Class III facial pattern. The soft tissue problems associated with anterior openbite included lip incompetency and tongue thrusting habit. We corrected the dental …

The etiology of skeletal Class II malocclusion may include excessive growth of the maxilla, deficient growth of the mandible, or the combination of both. Oral habits such as mouth breathing, tongue thrusting, and thumb sucking can cause anterior open bite. Meanwhile, the vertical overgrowth of posterior dentoalveoalr process may be another contributory factor. The treatment options for skeletal Class II malocclusion with anterior open bite should be planned according to the discrepancy of the inter-jaw relationship. If the discrepancy is mild or moderate, non-surgical approach with conventional orthodontic treatment will suit this situation. However, orthodontic treatment combined with orthognathic surgery …
