Severe anterior open bite with mandibular retrusion treated with multiloop edgewise archwires and microimplant anchorage complemented by genioplasty.
Abstract
In this case report, we introduce the combined use of multiloop edgewise archwire and microimplant anchorage to treat an 18-year-old Chinese woman who had a severe anterior open bite and a retrusive chin. Her diagnosis included a skeletal Class II base with severe anterior open bite, backward rotated mandible, and mesially tipped buccal dentition. The treatment plan emphasized vertical control of the posterior dentoalveolar dimension. Microimplant anchors were placed in the mandibular buccal segment to provide rigid anchorage and deliver intruding forces to the posterior teeth; a multiloop edgewise archwire was applied to generate uprighting forces to the maxillary and mandibular posterior teeth. Intrusion and uprighting of the posterior teeth contributed to the counterclockwise rotation of the mandibular plane, which consequently contributed to the facial profile improvement. Orthognathic genioplasty was implemented to further improve the chin prominence. After 1.5 years of retention, ideal intercuspation was evident, and the improved facial contour was stable.
