The effect of different reconditioning methods on bond strength of rebonded brackets: An in-vitro study.

Aim: To evaluate the effect of three different reconditioning techniques on the shear bond strength (SBS) of rebonded brackets.

Materials And Methods: Forty-five orthodontic brackets were bonded to human premolar teeth using Transbond™ XT. After debonding, the samples were randomly assigned into equal groups to assess three techniques for the removal of residual adhesive from bracket bases: in Group A, each bracket base was sandblasted with aluminum oxide; in Group B, each base was cleaned superficially with a greenstone bur; and in Group B, the bases were thoroughly abraded with a greenstone bur.
