Evaluation of the hardness of different orthodontic wires: A comparative study

Abstract

Background: Patients undergoing orthodontic treatment are increasingly demanding for the better esthetic. Mechanical properties of orthodontic wires are of paramount importance as they are deeply implicated in the efficacy of orthodontic therapy. Hence; the present study was undertaken for evaluating the hardness of different orthodontic wires. Materials & methods Results: Mean microhardness of the specimens of the stainless steel group, nickel-titanium group and beta-titanium group was 512.36, 356.12 and 302.47 respectively. While comapring in between the three study groups, significant results were otbaiend. Conclusion: Highest microhardness was seen among specimens of stainless steel group. However; further studies are recommended.
