Super Elastic Nickel Titanium

The Archwires with "Near Constant Force"

Acme Monaco supplies a wide variety of shapes and sizes in our super elastic nickel titanium product line. Material sizes are available from .012" through .021" X .025".  We supply the archwires in your preference of permanent etch or dimples.

"Shape Memory Effect"

The "shape memory effect" of the wire describes how our archwires work to return to their original shape after engagement, thereby providing effective movement of the patients' teeth. To assure that our archwires always maintain their archform and super elastic properties, these archwires are shape set during processing. This practice ensures that we will always supply you with the same shape and properties each and every time.
    
Clinical Advantages

Our super elastic archwires are an excellent choice if reduction of chair time, fewer wire changes, and longer intervals between appointments is your goal. These wires excel in early treatment aligning, rotating, and leveling of the patients teeth. They are often used for the treatment of a severe malalignment, due to their flexibility characteristics and easy insertion properties. Our archwires have a highly polished surface finish which aids in the reduction of friction and allows the brackets to slide easily along the wire. If there is concerned with the archwires sliding through the brackets or out of the buccal tube during use, Acme Monaco can provide a dimpled midline. This dimple will prevent the wire from sliding side to side after engagement.

Testing for Product Assurance

To assure optimum performance of our archwires, test methods to identify the forces and efficiency of the archwires during the loading (engagement) and unloading (working) are utilized.  When an archwire is engaged in the bracket, the archwire exerts a "working" force to align the teeth and remove the offset between the brackets.

To simulate actual use, our quality assurance department uses the three point bend test method per ISO15841. This testing accurately verifies the engagement and working forces of the archwire. The test measures the two forces, the force required to deform the archwire to a specified distance and the force the wire exerts to return to its original shape. To the right is an example of a three point bend testing fixture that is used. 

The results of the tests are normally represented by a chart, as shown below,  which depict the working forces of the super elastic nickel titanium archwires.

If your goal is high efficiency and reduction of chair time combined with minimal patient discomfort, you'll be impressed with Acme Monaco's Super Elastic Nickel Titanium Archwires!
