Metal brackets come in various materials, including common options like stainless steel, titanium alloy, nickel-titanium alloy, and gold alloy.
Stainless steel brackets are durable and cost-effective, while titanium alloy brackets are lighter and ideal for patients with nickel allergies.
Nickel-titanium alloy offers shape memory and superelasticity, and gold alloy brackets are known for their excellent corrosion resistance and biocompatibility.
Since the brackets all function the same way and are consumable, most people currently use the most cost-effective stainless steel metal brackets.
