Orthodontics We Cover orthodontics used to help restore oral structures to health and function and to treat serious medical conditions such as: cleft palate and cleft lip; maxillary/mandibular micrognathia (underdeveloped upper or lower jaw); extreme mandibular prognathism; severe asymmetry (craniofacial anomalies); ankylosis of the temporomandibular joint; and other significant skeletal dysplasias. Procedures include but are not limited to: • Rapid Palatal Expansion (RPE); • Placement of component parts (e.g. brackets, bands); • Interceptive orthodontic treatment; • Comprehensive orthodontic treatment (during which orthodontic appliances are placed for active treatment and periodically adjusted); • Removable appliance therapy; and • Orthodontic retention (removal of appliances, construction and placement of retainers).
