  Abstract 

Bonding of orthodontic brackets since its inception into orthodontics has made tremendous advances and continuous efforts are on to find better bonding materials. The retentive strength of these brackets on the tooth surfaces has increased considerably with time, but bracket dislodgement still continues to haunt Orthodontists. The clinician rather than choosing to replace the dislodged bracket with new one has the option of re-using the same old bracket after subjecting it to a suitable method of refurbishing. To overcome the delays associated with commercial recycling, in-house methods have been developed. The in-house refurbishing methods employed in this study are the sandblasting method, thermal method, adhesive removal by tungsten carbide bur and by Er: YAG laser. Er: YAG laser technique has the high refurbished shear bond strength which is followed by the sandblasting method, thermal method and the tungsten carbide method which had the least shear bond strength value and is not fit for clinical usage. The brackets after refurbishing were investigated by ESEM (Environmental Scanning Electron Microscope) to find out the effectiveness of the refurbishing methods. ESEM indicates that the adhesive removal was found to be almost complete with this group when compared to other groups.
