Nonsurgical Correction of Class III Malocclusion and Anterior Open Bite with Mini-Implant Anchorage

摘要

The combination of mandibular prognathism with anterior open bite poses a distinct challenge, often requiring both orthodontic treatment and orthognathic surgery. In adults, effective treatment has traditionally involved two-jaw surgery and superior repositioning of the maxilla with a Le Fort I osteotomy to close the anterior open bite, which reduces the anterior facial height by rotating the mandible upward and forward. This is often combined with a bilateral sagittal split osteotomy of the mandible to correct the mandibular protrusion.
