Debonding of ceramic brackets by a new scanning laser method.

Introduction: The purpose of this in-vitro study was to develop a new method to debond ceramic brackets by scanning with an Er:YAG laser.

Methods: Sixty bovine mandibular incisors were randomly divided into 2 groups of 30. Polycrystalline ceramic brackets were placed on their labial surfaces by using the orthodontic composite adhesive Transbond XT (3M Unitek, Monrovia, Calif) and light cured for a total of 40 seconds.
