Browse All ProductsAmerican Orthodontics produces this archwire range from its Sheboygan, Wisconsin facility, offering both NiTi (NT3) and stainless steel (304V) options in round and rectangular cross-sections. NT3 NiTi wire is fully active at room temperature with moderate springback forces — characterised by good springback — and is intended for initial and intermediate archwire stages rather than finishing. The 304V stainless steel wire uses vacuum-remelted alloy monitored with laser micrometer tolerances for dimensional consistency. Multi-strand stainless steel and posted arch configurations (0.032-inch posts at 8.3 mm centre spacing) expand the mechanical options available within this range. Standard packs contain 10 wires; stainless steel round wires are supplied in 50-wire packs.
Clinical Confidence
American Orthodontics formulated NT3 as a room-temperature active NiTi alloy that delivers moderate force levels and good springback throughout the initial and intermediate stages of treatment. Unlike heat-activated alloys, NT3 expresses its working force at ambient temperature, removing the need to account for intraoral temperature activation. Its springback characteristics allow it to engage significantly displaced teeth and return toward its programmed form, but it is not engineered for the precision torque expression required in finishing — a deliberate design boundary that directs clinicians toward stainless steel finishing wires.
The 304V stainless steel wire is produced from vacuum-remelted feedstock, a process that reduces inclusions and improves alloy homogeneity. Dimensional verification by laser micrometer ensures consistent cross-section across each production run. The multi-strand SS option provides greater flexibility per cross-section for cases requiring lighter forces at intermediate wire stages, while posted arches with 0.032-inch posts at 8.3 mm spacing are available for clinicians using inter-arch elastics or auxiliary mechanics tied to the archwire.
Clinical Quality
Fully active at room temperature with moderate springback forces. Suitable for initial and intermediate archwire stages.
Vacuum-remelted alloy with laser micrometer dimensional tolerances for consistent wire cross-section.
Multi-strand SS, posted arches, and three finish options extend the range's versatility across treatment stages.
Engineering
Room-temperature active alloy with moderate forces and springback properties. Designed for initial and intermediate stages — not finishing applications.
Vacuum-remelting reduces alloy inclusions and improves homogeneity. Laser micrometer inspection verifies dimensional tolerance on each production run.
Multi-strand construction provides greater flexibility per wire cross-section compared to solid SS, useful at intermediate wire stages or for patients with sensitivity to stiffer wires.
0.032-inch posts positioned at 8.3 mm centre-to-centre spacing are available for practices using inter-arch elastic traction or mechanics attached to the archwire.
Standard silver finish is available alongside 24k Gold Coated and Gold Tone options for patients who prefer less visible archwire appearance.
Round sizes from .012 to .020 and rectangular sizes from 16×22 to 19×25 cover the full standard progression through treatment.
Professional Use Cases
NT3 NiTi wires are suited for the leveling and aligning phases where springback engagement of displaced teeth is required. Not indicated for finishing.
304V SS wires handle intermediate mechanics and finishing stages where controlled torque expression and precise wire dimensions are required.
Posted arch variants enable inter-arch elastic use and auxiliary mechanics where hook-to-archwire attachment at defined spacing is required.
Why Choose
Chairside Reference
| Clinical Situation | Recommended Action |
|---|---|
| NiTi vs. SS Selection | Use NT3 NiTi for initial leveling and intermediate stages. Transition to 304V SS for finishing and torque expression stages. |
| Multi-Strand Indication | Consider multi-strand SS when a lighter force at a given cross-section is needed compared to solid stainless at the same size. |
| Posted Arch Use | Order posted arches when your mechanics require inter-arch elastic attachment at measured spacing along the archwire. |

Clinical Workflow
Begin with the appropriate round NiTi size for initial leveling. Progress through sizes toward rectangular NiTi as the arch levels, then transition to SS for finishing. NT3 is not recommended for the finishing stage.
Insert 304V SS wires at the appropriate stage of leveling and alignment. Verify wire dimensions against the slot size before insertion — laser micrometer tolerances ensure dimensional accuracy but the clinician should confirm the intended wire size.
When using posted arches, confirm post spacing (8.3 mm) is appropriate for the elastic force direction and attachment points in use.
Handle 24k Gold Coated and Gold Tone wires with care to avoid scratching the surface finish during placement and adjustment.
NT3 NiTi is designated for initial and intermediate stages only. For finishing mechanics requiring precise torque expression, transition to 304V stainless steel rectangular wires. Multi-strand SS wires have different force-deflection characteristics than solid SS of the same nominal size — account for this when sequencing.
