Crafted for precision in orthodontic applications, Acti4S wires feature a unique material ensuring true square or rectangular cross-sections with minimal corner radii. Their versatile joining capabilities through solder or welding, coupled with exceptional strength, make Acti4S ideal for orthodontic use. Rigorous quality controls prevent carbide precipitation, and continuous laser measuring maintains tight size tolerances. Each wire undergoes testing for tensile strength, extensive bend tests, and strict inspection for torque and arch shape. Acti4S wires prioritize durability, reliability, and patient safety in orthodontic practices.
