Shear Bond Strength of Rebonded Self Ligating Ceramic Brackets after Different Reconditioning Procedures (A comparative an In vitro Study)
Author(s): Zain Alabideen Ahmed* and Mustafa M Al-Khatieeb
Background: The aim of this study was to evaluate the effects of different recycling methods on shear bond strength and morphological changes of deboned mechanically retentive self-ligating ceramic brackets, then compare the findings with the new brackets of the same company. Material and methods: Forty-eight Damon® Clear™ self-ligating ceramic brackets with a mechanical retentive base were divided into two groups; the first group contained twelve new ceramic brackets (the control group), while the second group contained thirty-six new brackets which were bonded to unetched and slightly wet buccal tooth surface to allow an easy debonding of these brackets by tweezer, these debonded brackets then divided into three experimental (recycled) groups (12 per group): Recycled by sandblasting, irradiation by an Er, Cr: YAG laser and irradi..
