Over forty years ago 3M pioneered the use of nickel-titanium into orthodontists’ wire progression plans.
Today we offer three variations of Nitinol, three variations of stainless steel and Unitek™ Beta III Titanium –
the happy medium between nickel-titanium and stainless steel.
Strict controls over archwire dimensions, visual appearance and mechanical properties assure the highest
quality in the arch form, the force levels generated, and the malleability of the wire alloy.

Arch Form
For over a century, there has been a persistent search for the ideal arch form for human dentition. Changes
to arch form during treatment may result in instability and subsequent relapse, which can contradict this
search for the ideal arch form. There is an awareness that a great deal of variation exists from one human
arch form to another. With this in mind, 3M provides three distinct arch forms that reconcile the variation
in anterior curvature, inter-cuspid width, inter-molar width and the curvature from the cuspid to the
second molars.

Malleability
How easily a wire bends and how well it maintains the bends placed by the orthodontist are important
criteria for choosing the correct archwire material. Malleability (or bendability) is almost the opposite of
elasticity. Springy metals are difficult to bend, but wires that bend easily have minimal elasticity. Below is
a continuum of malleability* on a scale from one to ten, ten being the most bendable:

Force Levels
Force levels of archwires can be divided into two distinct categories. The engagement force, which is
known as the loading force, that the practitioner feels while handling the wire and ligating it into the
appliance. The working force, commonly referred to as the return or unloading force, is the force that
moves the teeth and is the force that the patient feels.
Engagement Force
Below is a continuum that describes the range of engagement forces from one wire alloy to another.
In this continuum, the smaller the number, the lighter the engagement force.

Working Force
Below is an example of comparison working forces between different types of archwires. In it you
will see the working force generated from 3 mm of deflection to zero for different wire families.

Archwire Analysis
Clearly your choices are numerous, and your orthodontic training and experience contribute to the overall
list of criteria you use. In addition to reviewing the criteria listed in the preceding pages, 3M consultative
representatives can provide an analysis and may be able to recommend a new wire progression for improved
efficiency in your treatment plans.

Nitinol Heat-Activated is a thermally activated super-elastic archwire. It
is the easiest of Nitinol wires to engage, and it delivers light continuous
forces that effectively move teeth with minimal discomfort to the patient.
• Can be cooled or chilled resulting in a softer, more pliable wire for
easy engagement
• Provides light continuous forces
• Force activation occurs around body temperature
• Available in square sizes making it excellent for early torque control
• Good bend retention when bent in hot water
• 10/pk unit of use
