Abstract EN
Objective.
The aim of this study was to compare the recycling of deboned ceramic brackets via an Er:YAG laser or via the traditional chairside processing methods of flaming and sandblasting; shear bond strength and morphological changes were evaluated in recycled brackets versus new brackets.
Materials and Methods.
3M Clarity Self-Ligating Ceramic Brackets with a microcrystalline base were divided into groups subjected to flaming, sandblasting, or exposure to an Er:YAG laser.
New ceramic brackets served as a control group.
Shear bond strengths were determined with an Electroforce test machine and tested for statistical significance through analysis of variance.
Morphological examinations of the recycled ceramic bracket bases were conducted with scanning electron microscopy and confocal laser scanning microscopy.
Residue on the bracket base was analyzed with Raman spectroscopy.
Results.
Faded, dark adhesive was left on recycled bracket bases processed via flaming.
Adhesive was thoroughly removed by both sandblasting and exposure to an Er:YAG laser.
Compared with new brackets, shear bond strength was lower after sandblasting ( p < 0.05 ), but not after exposure to an Er:YAG laser.
The Er:YAG laser caused no damage to the bracket.
Conclusion.
Er:YAG lasers effectively remove adhesive from the bases of ceramic brackets without damaging them; thus, this method may be preferred over other recycling methods.
