Abstract
An improved method is proposed for releasing brackets from bonded joints whereby also ceramic brackets can be removed. Herein, the layer of bonding agent is subjected to pulse-shaped heat input by transfer of heat from an instrument to the bracket, with a safety device allowing only a suitable amount of heat for the respective type of bracket to be transferred.
