This study was designed to ceramic brackets debonding through conventional remove and two lasers (980 nm diode laser and 1064 nm Nd:YAG laser) irradiation on the interface between the teeth and the bracket. After bracket removal, the enamel surfaces were examined using a digital microscope and the corresponding adhesive remnant index (ARI) score was assessed using 20x magnification. Experiments were conducted and comparisons made between the mechanical remove and laser methods, and results are presented that show lasers were good for clinical to effectively debonding ceramic brackets instead of conventional method. The laser assisted debonding of ceramic brackets is capable of lower the risk of enamel damage. Two lasers used in the experiment, the Nd:YAG laser with line beam scanning method was applied to the bracket removal compared to the diode laser. The suggested technique is expected to be useful in the field of orthodontics.
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.
