ARCHWIRES & ELASTICS:
Over the last century there have been numerous advancements in material science. These advances have proven to highly beneficial in the field of orthodontics, in addition to other disciplines in dentistry. The archwires and elastics used in orthodontics serve as the functional components of fixed orthodontic therapy. They exert forces on the teeth, resulting in tooth movement.
Before the time of E.H. Angle, archwires were made out of noble metals such as gold, platinum, iridium and silver. These wires lacked flexibility and tensile strength. With the passing of time, stainless steel was the one to displace noble metals as an archwire material.
Properties of wires:
The knowledge of the properties of wires can enhance the usage of archwires to effectively aid in tooth movement.
Stiffness is the ratio of the force to deflection of a member.
Strength the maximal stress required to fracture the wire.
Flexibility of the wire is the distance that it will bend elastically before deformation occurs.
Resilience is the energy storage capacity of the wire. It is a combination of strength and springiness.
Formability is the amount of permanent deformation a wire can withstand before it fractures or fails.
The ideal requisites of archwires are:
- Adequate strength
- Excellent formability
- Good springback
- Low friction
- High esthetics
- Good range
- High toughness
- Poor biohost
- Adequate springiness

What are the different types of archwires?
Stainless Steel Wires:
Stainless stell was deemed the material of choice for manufacturing archwires in the 20th century. It is an alloy of iron and carbon with the carbon content not exceeding 0.2%. Archwires made out of stainless steel have high stiffness, low springiness, are corrosion resistant and have good formability. They are generally sold at lower costs than other archwires. The readily be used as working archwires.
Nickel Titanium Wires:
NiTi alloys have characterisitic properties such as shape memory and super elasticity. These are due to its crystalline structure which is in the form of a body centered cubic (BCC) at higher temperatures called Austenite and a hexagonal closed packed structure at lower temperatures called Martensite. The different types of NiTi alloys used to make archwires include conventional and stabilized NiTi alloys, superelastic NiTi alloys, thermodynamic and graded thermodynamic NiTi alloys.
Beta Titanium Wires:
Also known as Titanium Molybdenum Alloy or TMA, beta titanium alloys were composed of a mixture of titanium, molybdenum, zirconium and tin. The wires made out of this metal were smoother, had good formability and were weldable.
Rubber elastics are extensively used in orthodontics both intra orally and extra orally. The latex polymer chains in orthodontics were introduced in the middle of the 20th century. They have simplified orthodontic therapy to a large extent. Elastic bands are made by slicing rubber tubes of different lumen sizes and wall thickness. The other elastomeric accessories used in orthodontics are elastic chains or power chains, elastic modules, elastic ligatures and elastic separators.
Types of Elastics:
According to their use, elastics can be grouped under the following heads:
- Class I elastics
- Class II elastics
- Class III elastics
- Anterior elastics
- Zig zag elastics
- Corss bite elastics
- Cross plate elastics
- Diagonal elastics
- Open bite elastics
- Box elastics
- Triangular elastics
- Vertical elastics
- M and W elastics and
- Lingual elastics
Storage of Elastics:
Elastics are to be stored in the refrigerator as recommended by manufacturers. This is because increased atmospheric pressure for a long time will decrease the strength of the elastics. Storing them in a refrigerator ensures a cold and dry environment which will increase the shelf life of the elastics.
Advantages of elastic ligatures over wire ligatures:
- They can be used as a substitute for wire ligatures in most situations
- Easier for the doctor
- Increased patient compliance
- No sharp ends
What are the brands selling archwires and elastics online?
Canadian Orthodontics, Ortho Technology, Horizon USA, Metro Orthodontics, Forestadent and D-Tech Ortho are a few of the many brands that sell archwires and elastics online
