<![CDATA[Introduction: Various chemical and mechanical methods are used to enhance the retention of adhesive tothe metal bases of the brackets.Inspite of several efforts,bracket failure is one of the commonest problemsfaced during treatment.Debonded brackets are generally recycled and reused.This study was designed tocompare the shear bond strength(SBS)of five commonly available mesh designs and to determine whichmesh design offers least reduction of SBS following recycling.Method: Sample consisted of 5 types of brackets with different mesh designs, bonded to 70 extracted humanpremolars.The SBS was checked using Instron universal testing machine.The brackets were recycled usingsandblasting procedure and were rebonded on the sample teeth.Bond strength testing was again carried outusing the same procedure.Results: Mean SBS of Discovery smart bracket with laser structured base was highest followed by 3MUnitek brackets.The brackets by American Orthodontics had lowest bond strength.After recycling withsandblasting procedure,an insignificant reduction in SBS was noticed in all five groups.Conclusion: Laser structured base design was superior to other bracket base designs.All five bracket typeshad optimal bond strength required for successful bonding both before and after recycling (>7.8 MPa).]]>
