This study evaluated the effects of four rebonding procedures on in vitro tensile bond strength of four filled diacrylate adhesives on orthodontic brackets. The four procedures were thermal reconditioning, chemical reconditioning, removal of residual adhesive with a green stone, and grinding the mesh base with a green stone. The mesh-base, stainless steel brackets were bonded to plastic cylinders and the tensile bond force necessary to cause bond failure was recorded. The initial bond strengths for the no-mix adhesive and both two-paste systems were significantly greater than the tensile bond strengths for any rebonding condition. Different rebonding conditions reduced tensile bone strength to differing degrees, using each of these three adhesives. The initial bond strength for the visible, light-cured adhesive was not significantly different from three of the four rebonding conditions and was lower than the initial bond strength of the other three adhesives.
