| Research Abstract |
This study investigated the effects of a diamond-like carbon (DLC) coating on frictional properties of orthodontic wires and brackets. DLC films were deposited on nickel-titanium wires, stainless steel wires and stainless steel brackets using the plasma-based ion implantation/deposition (PBIID) method. For friction test, the DLC coated wires and brackets showed significantly less frictional force than the non-coated specimens. The results of this study showed that the surfaces of the orthodontic appliance can be successfully modified by the PBIID method to create a DLC layer, which is beneficial for orthodontic tooth movement.
