Archwire alloys are available in various forms and shapes for multiple tooth movements like intrusion and retraction of teeth during orthodontic treatment. Coating on archwires can be done by various methods to improve its mechanical and surface corrosion properties. Chemical and thermal passivation, laser welding, laser melting, surface ion implantation and cathodic electrophoretic deposition of functional materials has been used as surface modification treatment to improve its thermal and mechanical properties. In this study, we are planning to do an in-vitro comparative assessment of the tensile strength of uncoated, polymer-drug coated and Teflon/tooth coloured orthodontic archwires.ddd |
