Aims: To evaluate the degree of change that may occur in reconditioning the titanium bracket via micro-
etcher. Materials and Methods: The sample consisted of (10) pure titanium brackets for each of
control and reconditioning brackets. The parameters of the reconditioned bracket (slot width, slot
depth, inter–wing gap, labio–lingual angle and base curvature angle) were measured and compared
with that of the control bracket. Results: The results showed no significant difference between the control
and reconditioned brackets of the slot parameters (width, depth, inter–win gap, labio–lingual angle)
and the bracket’s base curvature angle. While, the tensile bond strength of the control brackets
showed significantly higher mean value as compared with the recycled group. Conclusions: The reconditioning
of pure titanium brackets is recommended for reuse in the orthodontic treatment after sterilization

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
This study aims to evaluate the effectiveness of reconditioning titanium orthodontic brackets using a micro-etcher. The research focuses on the degree of changes that may occur in the bracket's slot dimensions and base curvature angle after the reconditioning process.
- The effects of micro-etching on bracket slot dimensions (width, depth, inter-wing gap, labio-lingual inclination angle)
- The impact of reconditioning on the bracket base curvature angle
- Comparison of tensile bond strength between control and reconditioned brackets
- Evaluation of the feasibility and recommendation for reusing reconditioned brackets in orthodontic treatment
- Analysis of the micro-etching method's impact on bracket retention and bond strength
