Stainless steal orthodontic brackets recycling using micro–etcher

الملخص EN

Aims : to evaluate the effects of the micro–etching procedure on the bracket’s slot and base parameters and on the tensile bond strength of the recycled brackets.

Materials and Methods: the sample was 20 stainless brackets grouped into; control brackets group (10) and de–bonded brackets group (10).

The de– bonded brackets reconditioned with micro–etcher.

The data subjected to the statistical analysis at ≤ 0.05 significant level.

Results : demonstrated that the use of micro–etcher for recycling the de–bonded brackets do not affect the bracket’s slot and base parameters whereas affected the bond strength of the recycled brackets.

Conclusion : the micro–etcher (sand basting) is recommended for recycling the de–bonded stainless steel brackets and reuse them in orthodontic treatments.
