An orthodontic appliance such as a bracket or buccal tube is made of a stainless steel alloy that includes chromium, nickel and precipitates of titanium. The alloy imparts a relatively high strength to the appliance and is resistant to corrosion. Optionally, the appliance has structural sections that are smaller than corresponding sections of comparable appliances when made of conventional stainless steel alloys used in orthodontic appliances. As a consequence, the appliance is more aesthetic when mounted on a tooth of a patient undergoing treatment.
