Reconditioning of Debonded Pure Titanium Bracket (Using Micro–etcher)

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.
