Stainless steelThe main objective of a dental laboratory is to manufacture clinically acceptable devices for a profit. As a laboratory owner, it is essential to select the most affordable, yet convenient materials. Stainless steel is less expensive than nickel-titanium and since it is the most commonly used orthodontic wire, it would be most convenient for a laboratory to utilize. The main objective of orthodontic treatment is to obtain good aesthetics in the least amount of time. It has good formability, thus wires can be bent to required specifications. Stainless steel has been clinically proven to be biocompatible in the oral cavity therefore it will harm or cause infectious developments in the patient’s mouth. Stainless steel orthodontic wires can be soldered and weldered, unlike nickel-titanium which is essential when attaching auxiliaries or when fabricating certain removable appliances such as the space maintainer or a distally extended labial bow. Both nickel-titanium and stainless steel are resistant to corrosion, owing to the oxide film characteristic of their surface topography.
