AIM: To evaluate the effect of three different reconditioning techniques on the shear bond strength (SBS) of rebonded brackets. MATERIALS AND METHODS: ≤ 0.05). CONCLUSION: All reconditioning methods were found to have a positive effect, but the sandblasting technique performed best. Brackets reconditioned by sandblasting and superficial grinding mainly showed mixed-type failure, while in samples thoroughly reconditioned by greenstone bur, bonding failure occurred predominantly at the adhesive/bracket interface.
