What material are ligature ties commonly made from?

Ligature ties are commonly made from stainless steel wire due to their strength and durability. Stainless steel is a preferred material in dentistry because it provides excellent support during orthodontic treatments. The rigidity of the wire allows for effective holding of orthodontic wires in brackets, ensuring they remain in position while exerting necessary forces on the teeth.

Additionally, stainless steel is resistant to corrosion, which is crucial in the moist environment of the mouth. This resistance contributes to the longevity and functionality of the ligature ties, as they need to withstand various conditions during treatment. Other materials listed, such as plastic composite, silicone, and cotton thread, do not offer the same combination of strength, elasticity, and stability that stainless steel does, making them less suitable for the purpose of securing orthodontic components effectively.
