Abstract

This study was designed to find an effective way of ceramic brackets debonding through the laser irradiation on the interface between the teeth and the bracket. Various laser parameters were applied to remove orthodontic brackets. After debonding, the adhesive remnant index (ARI) and the degree of enamel fractures were examined with microscope. The laser-assisted debonding be capable of lowering the risk of enamel damage and the less adhesive residue. The results indicated that the line laser system can be successfully applied to ceramic bracket remove tool. This method is expected to be useful in the field of orthodontics.
