OBJACTIVE: The authors introduced a novel wire system aiming to achieve optimal goals of tooth movement without multiple wire changes or sophisticated wire bending. MATERIALS AND METHODS: The system was composed of a single wire for all phases of treatment. The archwire was composed of NiTi coil springs connecting delta-shaped segments of 0.018˝ × 0.025˝ Titanium Molybdenum Alloy (TMA) segments to fit the 0.018˝ × 0.025˝ bracket slot, or 0.022˝ × 0.028˝ TMA segments to fit the 0.022˝ × 0.028˝ bracket slot. The coil spring was closed and packed in design. The coil-spring loops were constructed with 3 mm lumen. The wires were designed in three sagittal forms and the system provided nine forms of archwires. RESULTS: The wire systems have been an important component of treatment since the development of orthodontic science. Over time, the philosophy has evolved from endorsing wire bending to straight-wire treatment and then to custom-made archwires. CONCLUSION: This wire system was designed to be used as a “single-wire for the case” across all stages of treatment to achieve the ideal goals without any biological damage.
