title: Laryngeal impaction of an archwire segment after accidental ingestion during orthodontic adjustment.
abstract: Orthodontic archwires or fractured appliances that are accidentally swallowed can become lodged in the airway or gastrointestinal tract. Inadvertent ingestion or aspiration of an appliance or archwire piece during orthodontic appliance adjustment is a medical emergency with potentially serious complications, including possible death from asphyxiation. This article reports the accidental ingestion of a piece of orthodontic archwire that became impacted in the larynx; it was subsequently retrieved. Some potential complications are discussed, along with suggested precautions to prevent such mishaps when using fixed appliances.
