What Are Invisalign & How Do They Work?

Invisalign Braces

What Is Invisalign?

The brand name of a type of thin clear aligner used in orthodontic treatment, Invisalign is an aligner made from a flexible thermoplastic material named SmartTrack.

A teeth-straightening treatment, it is increasingly being used as a popular alternative to the old-school metal braces.

It is an orthodontic treatment that correctly aligns teeth and is designed to make orthodontic treatment less noticeable or 'virtually invisible' and is thus called “Invis-align.”

Invisalign aligners are clear coverings that fit tightly over the teeth and are much less noticeable than the brackets and wires of traditional braces.

Clear aligners are prepared from computer-generated images and impressions taken from the mouth to change the position of the teeth. 

Traditional braces use fixed wires to pull the teeth into alignment, while with Invisalign the teeth are aligned by a series of moulds that, across a series of months, force the teeth into their newer, improved position.


What Types of Dental Issues Can Invisalign Correct?

Useful for many purposes, Invisalign is especially suitable for those wanting to improve their smile or arrange their teeth in a more orderly fashion.

It solves most common dental conditions, such as Overly crowded teeth, Crossbite, Underbite, Open bite, Deep bite, Gaps in teeth etc

The Invisalign treatment can help:



Extremely helpful in correcting the misalignment of teeth in teenagers, Invisalign braces are ideal for teens. 

The clear aligners help to achieve a glowing smile and improve dental health at an age where teenagers are filled with self-consciousness because of the appearance of their teeth. 

A shorter treatment period and easier use make Invisalign an ideal treatment for teenagers wanting to improve their smiles.



Unlike olden times, correctional dental work is now being chosen by more and more adults making Invisalign an ideal option for adults seeking flexibility in their alignment procedure and wanting to achieve an improved smile without having to use a highly conspicuous metal brace.


How Does Invisalign Work?

Practically an invisible way to straighten the teeth using the 3D computer-imaging technology, Invisalign technology takes the present and the final straightened position of the teeth, to formulate a treatment plan that will gradually align the teeth.

The current Invisalign is replaced every few weeks with a new set of aligners until the patient has flawlessly straightened teeth and a perfect smile.

Made out of clear, medical-grade thermoplastic, the material of Invisalign is so smooth, that it helps prevent any discomfort even when one is sleeping.


Invisalign and the Movement of the Teeth

A controlled force is applied to different parts of the teeth using Invisalign, during different phases of the treatment.

Only the specific teeth can move with each new set of aligners one wears, making them a much more controlled, and less painful way of aligning teeth as compared to the metal braces.
