What is Invisalign and How Does it Work?

The Invisalign Process

Invisalign is a corrective dental system pioneered by Align Technology. It has become quite popular that 12.8 million patients to date have benefited using it. What is Invisalign? It’s a clear aligner designed and customized to fix crooked or misaligned teeth. Know how it works and the different alignment issues it can correct.

The Invisalign system uses a thermoplastic material that is patented as SmartTrack to correct crooked teeth. Hence, it is soft and more convenient to use. The plastic is clear yet strong making wearing it more aesthetically pleasing. It is also removable in instances when you have to eat and drink, as well as clean it. These are Invisalign’s advantages over what is traditionally used to correct misalignment – braces, with their brackets and metal wires.

How does Invisalign work?

A sequence of clear aligners will be used throughout treatment. The aligner trays that fit into the upper and lower jaws are based on photos and 3D digital scan of the patient’s teeth, then fabricated using 3D printing technology. Each aligner is intended to move the teeth a quarter of a millimeter at a time in the direction desired. This may take a few weeks, and then the patient gets the next aligner batch to make further movements in the next weeks. This becomes complete when the desired positioning of the tooth or teeth concerned is achieved. Your dentist may apply SmartForce attachments to your teeth before or during your Invisalign treatment. They give your aligners leverage, acting like handles.

What issues does Invisalign fix?

The system can be used to correct most types of bite problems and tooth alignment problems. It’s effective in all age groups and preferred for patients who previously suffered bone and gum loss. Sometimes patients as young as six can benefit, as well as mild to moderate to severe crowding.

However, in cases of severe overbite or underbite, or a tooth that is rotated more than 20 degrees, large gaps between your teeth, or intrusions/extrusions, the better option are braces. There may be cases where Invisalign may not work for patients. Some patients may not be able to give significant cooperation; for example, the aligners are meant to wear for 20 to 22 hours a day, replacing them with a new set every one to two weeks. This means frequent dentist visits.

Invisalign may not work for all, but for those others, it is a great option for confident smiles.
