TMA (Titanium-Molybdenum Alloy) straight wire—also known as Beta-Titanium—is a specialized archwire that serves as an intermediate tool between highly flexible Nickel-Titanium (NiTi) and rigid Stainless Steel (SS). It is valued for its unique combination of strength, flexibility, and excellent formability, allowing orthodontists to make permanent bends while delivering consistent, moderate forces. 

• Intermediate Stiffness: TMA provides approximately 40% of the force of an equivalent stainless steel wire, making it softer and more comfortable for patients while offering more control than NiTi.
• High Springback: It has about twice the “range of action” or springback of stainless steel, meaning it can undergo significant deflection and still return to its original shape.
• Weldability: TMA is the only orthodontic wire that can be directly welded without losing its mechanical properties or requiring solder, allowing for the attachment of custom hooks or loops.
• Nickel-Free: Unlike many other orthodontic wires, TMA is biocompatible and nickel-free, making it an ideal choice for patients with nickel sensitivities
