Dental braces

Dental braces (also known as orthodontic braces, or braces) are devices used in orthodontics that align and straighten teeth and help to position them with regard to a person’s bite, while also working to improve dental health. They are often used to correct underbites, as well as malocclusions, overbites, cross bites, open bites, deep bites, crooked teeth, and various other flaws of the teeth and jaw. Braces can be either cosmetic or structural. Dental braces are often used in conjunction with other orthodontic appliances to help widen the palate or jaws and to otherwise assist in shaping the teeth and jaws

* Traditional metal wired braces are stainless steel and are sometimes used in combination with titanium. Traditional metal braces are the most common type of braces. These braces have a metal bracket with elastic (rubber band) ties holding the wire onto the metal brackets. The second most common type of braces are self ligating braces that do not require the need of elastic ties. Instead, the wire goes through the bracket. Often with this type of braces, treatment time is reduced, there is less pain on the teeth, and requires less adjustments than traditional braces.
* «Clear» braces serve as a cosmetic alternative to traditional metal braces by blending in more with the natural colour of the teeth or having a less conspicuous or hidden appearance. Typically, these brackets are made of ceramic or plastic materials and function in a similar manner to traditional metal brackets. Clear elastic ties and white metal ties are available to be used with these clear braces to help keep the appliances less conspicuous. Alternately, clear braces[7] can be self-ligating, meaning the wire clips into the bracket without the need for ligatures. Clear braces have a higher component of friction and tend to be more brittle than metal braces. This can make removing the appliances at the end of treatment more difficult and time consuming.[citation needed]

* Gold-plated stainless steel braces are often employed for patients allergic to nickel (a basic and important component of stainless steel), but may also be chosen because some people simply prefer the look of gold over the traditional silver-coloured braces.
* Lingual braces (examples of which are Harmony, SureSmile QT,) are custom made fixed braces bonded to the back of the teeth making them invisible to other people. In lingual braces the brackets are cemented onto the backside of the teeth making them invisible while in standard braces the brackets are cemented onto the front side of the teeth. Hence, lingual braces are a cosmetic alternative to those who do not wish the braces to be visible.
* Titanium braces resemble stainless steel braces but are lighter and just as strong. People with allergies to the nickel in steel often choose titanium braces, but they are more expensive than stainless steel braces.
