When we refer to, “Martensitic” we are talking about the cold state or the soft state of nickel titanium. These archwires have martensite present at room temperature, but go through a transformation change to austenite, which strengthens the wire once placed in the mouth. Our Austenitic archwires go through a similar transformation, but at a much lower temperature. The austenitic archwires appear stiffer at room temperature. Our Martensitic wires exhibit superelastic (SE) properties as well as shape memory properties. Our Austenitic wires exhibit only SE properties. Martensitic archwires are the wire of choice for severe malocclusions, and offer earlier rectangular wire engagement.

TIP: If you would like to test a piece of martensitic wire or you just want to see how this stuff works, try the following:

Our "RCS" (reverse curve of spee) archwires combine the advantages of our SE Two strength with the added benefits of a reverse curve. Quality manufacturing and inspection methods ensures you will receive a consistent arch shape every time! All of our "RCS" arch wires are carefully finished to ensure that the wire slides easily through the bracket slot and applies continuous force for ideal biological tooth movement. This is a must in all class II corrections involving deep bite and open bite cases. Use "RCS" archwires in conjunction with springs or elastomerics for retraction, or turn the "RCS" inside-out for arch expansion. We manufacture several shapes and sizes to cover many specific techniques. The possibilities are endless with our reverse curve of spee archwires!

NITI RCS Type 1 Archwires

Our original and most popular, this shape offers a deeper “rocking chair” radius. This radius gives the wire more force in curve of spee correction. TYPE 1 exerts more force when correcting severe curve of spee cases.

Benefits: Bite opening and closing Initial leveling and aligning Arch consolidation and expansion Retraction of flared, protruding incisors Deep bite correction Open bite correction.

The TYPE 5 is the arch of choice for tilting back the molars for anchorage purposes. It maintains uprighted molars while using auxiliary arches nitinol retraction springs for the cuspids and is excellent for lower anterior teeth intrusion and leveling the occlusal plane.

Benefits: Closing bite action on the upper arch Easily puts curve of spee on the upper arch Expands the lower arch Torques the molars buccally

The Multi-Modulus is our most technologically advanced arch wire. This wire was designed to generate the right forces to the three major regions (centrals, premolars and molars) of the mouth. The central region exhibits Martensitic 2 force values which allows easier ligation earlier in treatment, the premolar region exhibits SE Two force values which enhances anchorage and provides more stability. The arch wire is clearly marked with FDA White listed ink to show where each section begins and ends. This will aid the clinician by identifying each section of the wire.

This wire provides many benefits for the clinician such as more patient comfort. By moving the teeth over a greater period of time the patient remains comfortable and requires fewer visits. This wire can be ligated earlier in treatment and may also provide a one wire treatment.

FEATURES: Gentle superelastic forces in the central region. Forces gradually increase from premolar region to distal ends. One arch wire that delivers ideal forces to specific regions of the mouth for optimum individual tooth movement. Torque values gradually increase as the bending forces increase. (see force graph )

A Brief History

During the mid 1970's Dr. Andreasen was instrumental in developing nickel titanium rectangular arch wires. It was his patent (#4,037,324) that introduced light torque to orthodontics through rectangular nickel titanium arch wires. As Dr. Andreasen continued his research with nickel titanium arch wires, he realized there was a recurring problem. The wires were so resilient they would slide through the brackets as the teeth started to align, causing the wire to slide out of the buccal tubes. This caused irritation to the patients, and in many cases emergency visits to the doctor to cut or replace the wire.

Doctor Andreasen was impressed with the clinical results he was able to get using nickel titanium wires, but was determined to eliminate the sliding concern he and his colleagues shared. After carefully studying the problem they developed and arch wire with a strategically placed lateral protrusion that Ultimate Wireforms calls "The Dimple (TM)". In February of 1990 Dr. Andreasen was awarded a patent (#4,037,324) for his efforts. Dr. Andreasen states in his patent that the lateral protrusion which is placed in the centerline of the wire must b�protrusion in any direction will stop the arch wire from sliding through the bracket, the safest and most effective direction of the protrusion is a vertical dimple 90 degrees outside of the plane of the archwire.

"The Dimple(TM)" option

Our vertical dimple was carefully designed to protrude occlusally or gingivally (it’s your option) and not to protrude labially or lingually. The vertical protrusion eliminates the concern of a lingual protrusion rubbing against the teeth and potentially removing enamel or labial protrusion which can cause lip irritation. "The Dimple(TM)" is a permanent center mark in the arch wire. "The Dimple" eliminates the need to struggle with the arch wire by trying to cinch behind the buccal tubes and virtually eliminates the possibility of the wire sliding out of the buccal tube. "The Dimple" permanent center line option is one to seriously consider if reduced chair time is important. Ultimate owns a semi-exclusive right to manufacture Dimpled arch wires from the University of Iowa

The Ink Centermark Option

The Ink centermark option is the industry’s original design and provides the clinician with a single red line for a lower and a single black line for an upper. This is not a permanent centermark, the centermark can rub off due to normal wear & tear in the oral environment. Ultimate uses only FDA White listed inks to ensure your patients safety.

The Etching Option

The etched centermark gives the clinician a third centermark option. This centermark is etched into the wire and does not rub off. It is dark grey to light black in color. Three (3) lines indicate an upper arch form and a single (1) line indicates a lower arch form. The permanent etched centerline is becoming more popular than our original ink centermark.

Today, clinicians around the world are well aware of the luxury in using nickel titanium products. The shape memory properties and biocompatibility of the alloy offer enhanced patient comfort and a variety of techniques that was not possible until the introduction of nickel titanium to the orthodontic industry.

Since the thirties many other materials have been used to manufacture coil springs for our industry, but none has been able to compare with nickel titanium. In this section, we will explain the differences between stainless steel and nickel titanium adjustable force and superelastic coil springs and why the exclusive characteristics of this alloy make it the ideal alloy for orthodontic coil springs.

Stainless steel coil springs exert a high force initially, which can be uncomfortable to the patient, but lose their force at a quick rate as the tooth moves. As you compress (load) an open wound stainless steel coil spring to solid (all coils in contact with one another) the load builds quickly. When you release (unload) the spring from solid slowly (simulating tooth movement) you will find that the force generated, as the coils start to separate, is less than it was while being compressed. This is a natural phenomenon called hysteresis. The force generated while unloading the spring is always less than loading. All of our graphs illustrate the unloading force values, because these are the values that are important to us. The unloading force is the actual force that we rely on to move the teeth. Nickel titanium coil springs also exhibit less force while unloading, but at a much smaller ratio. Stainless steel springs will take a permanent set (not return to their original length) when compressed to solid and then released. Nickel titanium coil springs will not take a permanent set and will return fully to their original length.

All of our nickel titanium coil springs are made out of the finest alloy available. Our coil springs allow you to open or close spaces with optimum efficiency and control. The following information will help you understand what criteria determines the force values of any type of coil spring discussed, assuming the same material is being used.

Design Function: Reducing the wire size of the spring. Product Result: Will lower the force generated by the spring. Example: .010”x.030”x7” > .009”x.030”x7” Design Function: Adding active coils to the section of spring being used. Product Result: Will lower the force generated by the spring. Example: .010”x.030”x10mm > .010”x.030”x15mm (more coils in longer length spring) Design Function: Increasing the lumen (diameter) of the spring. Product Result: Will lower the force generated by the spring. Example: .010”x.030”x7” > .010”x.035”x7”

Variable Force Springs vs. Superelastic Springs

Over the past several years Adenta’s unique Variable force nitinol coil springs have become an extremely popular tool with clinicians. Unlike superelastic springs, which exhibit a relatively constant force depending on the wire size and lumen, the variable force springs allow the clinician to generate the force he or she needs with one spring. These springs have been designed to gently increase force as the spring is extended (closed coil spring) or compressed (open coil spring), so the doctor may utilize one spring to exert the optimum force needed. This eliminates the need for a large inventory of various superelastic springs with different wire sizes and lumens to achieve the desired forces. We do of course realize that some clinicians will demand a superelastic spring. For that reason we do offer a line of superelastic springs. Please don't ever hesitate to call our R&D department should you need a special spring. We look forward to working with you to develop your particular ideas.

Superelastic Coil Springs

In addition to our stainless steel and nickel titanium variable (adjustable) force coil springs, we also offer nickel titanium superelastic coil springs. This is the correct selection, should you feel the need of a constant force throughout the mean deflection range. The superelastic coil springs were designed and manufactured to produce a specific force throughout the working range of the spring. Like the adjustable force springs, our superelastic coil springs will not take a permanent set. They return to their original length after normal deflection.

Variable (Adjustable) Force Coil Springs

Our line of adjustable force coil springs are our most popular springs, because they offer all of the benefits of a superelastic nickel titanium coil spring, but they will also help to reduce your inventory. These springs were designed to gradually increase in force as the spring is extended (closed coil spring) or compressed (open coil spring), allowing you to generate the precise force needed for a specific case. Now there is no reason for you to maintain a large inventory of various sizes of stainless steel or superelastic coil springs. These coil springs will generate the consistent gentle force you need without taking a permanent set. Our adjustable force springs offer you the best of both worlds, reduced inventory and flexibility.

Coil Springs With Eyelets

Adjustable force and superelastic closed coil springs are available with eyelets. These stainless steel eyelets attach to each end of our adjustable force or superelastic closing (closed coil) springs. This allows you to easily engage a bracket hook, sliding hook, buccal tube hook and/or posted arch wire hooks. We recommend that you place one eyelet over the distal hook and gripping the leading edge of the front eyelet with pliers, pull gently forward to engage your anterior hook.

Compression Springs

Our variable (adjustable) force nickel titanium open coil springs offer you tremendous value. You can now enjoy the benefits of a nickel titanium coil spring without the cost of holding a large inventory. We offer our adjustable force nickel titanium coil springs in 15 inch lengths on a spool or three 7 inch lengths in a tube. The same premium quality springs in your choice of packaging.

Our superelamean deflection of the spring. We offer our superelastic open coil and closed coil springs in a variety of sizes.

Distalizing (Open/Closed) Coil Springs

Our superelastic open/closed coil Distalizing spring is a revolutionary nickel titanium coil spring that offers you an alternative to headgear or lip bumpers. You can now distalize molars easily with optimum patient comfort. These springs are designed to produce the specified amount of force wheand insert on tyou will prevent the spring from rotating off of the arch wire. Using an adjustable arch wire lock, compress the spring to activate. The unique properties of the spring will do the rest. Available in 15” lengths on spools or 7” lengths in tubes
