Abstract:
A 23-year-old woman with condylar resorption and a skeletal Class II pattern and anterior open bite were treated with 4 premolar extractions and temporary skeletal anchorage devices in both maxillary and mandibular arches. Before the start of orthodontic treatment, her unstable condylar position was stabilized with a stabilization splint for 6 months. Sequential evaluation of her condylar position was performed using a mandibular position indicator. The total active orthodontic treatment time was 30 months. After treatment, her occlusion, soft tissue profile, and unstable jaw position were significantly improved. Posttreatment records after 36 months showed excellent results with a good, stable occlusion.
