TMA Wire — Titanium Molybdenum Alloy | Round & Rectangular | Upper & Lower
TMA wire, composed of Titanium Molybdenum Alloy, occupies the middle range of the orthodontic archwire sequence between stainless steel and nickel-titanium. Its lower modulus of elasticity compared to stainless steel means it delivers lighter, more continuous forces over a greater range of activation, making it suitable for detailing and finishing stages. Available in round sizes .014, .016, and .018, and rectangular sizes 16x22, 16x25, 17x25, and 18x25, these wires are sold individually for both upper and lower arches. Manufactured in China.

Clinical Confidence
Controlled Force Delivery Across the Archwire Sequence
TMA wire has a modulus of elasticity approximately one-third that of stainless steel, which means that for the same deflection, it delivers a lighter force than an equivalent stainless wire. This property makes TMA particularly useful during the detailing and finishing stages of treatment, where large deformations are no longer needed and the goal is precise tooth positioning using gentle, sustained forces. The material also allows bending without springback loss that would be encountered with stiffer wires, making it practical for auxiliary bends and torque adjustments.
The range of sizes — round .014 through .018 and rectangular 16x22 through 18x25 — gives clinicians the flexibility to select the cross-section appropriate to the stage of treatment and the specific tooth movement being addressed. Rectangular TMA wires can express torque through the bracket slot, while round TMA wires are useful for lighter initial tooth movement in TMA-based sequencing or for auxiliary springs. Sold per wire for upper and lower arches, ordering can be tailored to per-patient needs.

Engineering
Key Features
Lower Modulus of Elasticity
TMA's reduced stiffness compared to stainless steel produces lighter forces at equivalent deflection, supporting gentle tooth movement during finishing.
Formable Alloy
TMA can be bent to incorporate auxiliary torque, tip, and rotation corrections without the springback characteristics of stiffer wire alloys.
Round Size Options
Available in .014, .016, and .018 round cross-sections for use at various stages of treatment or as auxiliary archwires.
Rectangular Size Options
Rectangular sizes 16x22, 16x25, 17x25, and 18x25 allow torque expression through the bracket slot during finishing and detailing.
Upper and Lower Arch Versions
Available for both upper and lower arches, sold as individual wires to match per-patient arch requirements.
Professional Use Cases
Clinical Applications
Orthodontic Finishing and Detailing
TMA's lighter force delivery and formability make it suitable for the final stages of fixed appliance treatment where precise tooth positioning is the goal.
Torque Expression
Rectangular TMA wires can be used to deliver or adjust torque through the bracket slot without the stiffness associated with stainless rectangular wires.
Auxiliary Springs
Round TMA wire can be formed into auxiliary springs for uprighting, tipping, or open-coil applications where light force is preferred.

Chairside Reference
Chairside Decision Guide
| Clinical Situation | Recommended Action |
|---|---|
| Round vs rectangular | Choose round TMA (.014–.018) for lighter force applications or auxiliary spring fabrication. Choose rectangular TMA (16x22–18x25) when torque expression through the bracket slot is needed. |
| TMA vs stainless at finishing | TMA delivers lighter forces than stainless steel at equivalent wire dimensions, making it preferable when residual tooth movements are small and lighter mechanics are indicated. |

Clinical Workflow
Application Guidelines & Reference
Application Application Guidelines
-
1
Wire Selection
Select the cross-section based on the stage of treatment and the bracket slot dimension. Confirm rectangular wire dimensions fit the slot before cinching.
-
2
Bending
TMA can be bent with standard pliers. Avoid repeated bending at the same point as TMA, while formable, will fracture if work-hardened excessively.
-
3
Ligation
Ligate with standard elastomeric or stainless ligatures. Confirm full seating of the rectangular wire in the bracket slot before proceeding to ensure torque is being expressed.
-
4
Sequencing
TMA is typically introduced after leveling and aligning with NiTi wires and before final stainless detailing, or as the finishing wire when lighter forces are preferred over stainless.
Pairs With Best Used With
- Standard or self-ligating orthodontic brackets
- Orthodontic pliers (bird-beak, torquing pliers)
- Elastomeric ligatures or stainless steel ties
- Open-coil NiTi springs for space maintenance
Professional Dental Use Professional Use Notice
TMA wire should not be welded or soldered as the alloy composition changes under high heat. For soldered stop or hook additions, use stainless steel wire instead. Avoid repeated sharp bends at the same location; TMA is formable but will notch and fracture if repeatedly worked at a single point.
