Dentists are commonly faced with the decision of what to do with detached or inaccurately positioned brackets that require re-positioning during treatment. One solution is to reuse the brackets without compensate for bond strength. The purpose of this study was to evaluate the effects of the surface treatments of the detached metal bracket on the shear bond strength (SBS) of orthodontic brackets bonded to bovine.
Eighty detached brackets without any damage were selected and twenty new brackets (CTL) were prepared. Twenty used brackets, which had less than 5% residual adhesives in the base, were not treated, but cleaned with ultrasonic cleaner using ethanol (EXP-1). Used brackets were ground with green stone until mesh patterns were exposed (EXP-2), were sandblasted with alumina particles (EX-3), and were sandblasted subsequent to green stone grinding (EXP-4). One hundred bovine teeth were used for bracket bonding test. SBS test and adhesive reminant index (ARI) evaluation were performed, and the data were analyzed using ANOVA test (p = 0.05).
EXP-1 showed the significantly low SBS (8.24 ㎫, p＜0.05), but higher bond strength than the clinically required bond strength. EXP-2 showed the lowest SBS (6.59 ㎫) among experimental groups. EXP-3 showed the highest SBS (11.99 ㎫), but no significantly different with CTL (11.50 ㎫). Average SBS of EXP-4 was 10.20 ㎫, it was not significantly different with CTL or EXP-3.
