Heat Activated Nitinol w/Copper remains soft at room temperature for easy wire insertion, even in the most severe cases. This wire provides continuous force even at very small deflections, which reduces the frequency of wire changes. The smoother surface finish reduces friction for faster tooth movement. It's unloading (springback) properties facilitate faster and more efficient tooth movement. Heat Activated Nitinol w/Copper allows the wire to be easily engaged before full activation at body temperature.
