title: Relapse of a maxillary median diastema: closure and permanent retention.
abstract: The purpose of this article was to describe the closure of a maxillary median diastema of a 26-year-old woman that had been corrected before during orthodontic treatment but reopened after dental trauma in a car accident. A clear esthetic device made from a tray like those used for home bleaching was used, providing a comfortable, nearly undetectable, and efficient solution. A permanent fixed retainer was bonded again to the maxillary central incisors to prevent relapse.
