The Eighteen-month Follow-up of Orthodontic Treatment Outcome with Bony Anchorage for A Severe Skeletal Class II Anterior OpenBite Malocclusion - A Case Report
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 will be required if the discrepancy is severe. This paper reports the conventional orthodontic treatment with application of mini-plates and transpalatal arch for an adult female patient with severe malocclusion of skeletal Class II and anterior open-bite. The stability of the outcome was evaluated in one and half years after the active treatment.
