What material is often used to fabricate ligatures?

The use of metal wire to fabricate ligatures is well-established in various applications such as orthodontics. Metal wire ligatures provide strong and durable support for securing archwires to brackets, ensuring that dental and orthodontic treatments proceed effectively. The tensile strength of metal wire allows for precise adjustments and maintains the desired tension needed for effective treatment outcomes.

In contrast, while materials like thermoplastic and composite resin may be used in dental applications, they are not as commonly associated with ligature fabrication. Silicone rubber, although beneficial in certain medical or dental contexts for its flexibility and comfort, would typically not provide the same structural support as metal wire in maintaining the position of orthodontic components.

Thus, the selection of metal wire as the material for ligatures is grounded in its mechanical properties, enabling it to meet the demands of orthodontic interventions.
