Invisalign is one of the most popular clear aligners that are used to help straighten and improve the shape and appearance of your teeth.

Whether you have decided that you want to improve the appearance of your teeth, or if it is something that your orthodontist or dentist has recommended, Invisalign is great for those who feel that their teeth need to be improved.

What is Invisalign made of?

In this guide, we’ll be taking you through everything you need to know about Invisalign, from what it is to the materials that Invisalign is made from and other relevant information that you need to know.

This allows you to make a fully-informed decision about whether Invisalign is the right choice for you.

What Is Invisalign?

Invisalign is a brand of clear aligners that are custom-made for all patients as they produce a 3D scan of your mouth and create the aligner to fit your teeth perfectly to ensure that they will move naturally without any risks.

Invisalign aligners are made from BPA-free plastics that help move your teeth into position gradually through gentle pressure, thanks to the customized fit.

Throughout the treatment, patients are provided with new aligners to ensure that their teeth are not in any pain.

What Is Invisalign Made From?

As stated above, Invisalign aligners are made from BPA-free plastic. The plastic is known as polyurethane resin and comes in customized trays that are guaranteed to fit.

Polyurethane resin is made from a mix of 1.6 hexanediol and methylene diphenyl diisocyanate, meaning that it is classed as a medical-grade material that also boasts a high level of molecular weight.

What makes polyurethane resin such a strong material is that it is biocompatible and helps to shift the teeth gradually using gentle pressure over time.

What this means is that you shouldn’t have any issues as your teeth are moving.

You’ll also be able to carry on as normal as it doesn’t affect your ability to smile or speak. However, bear in mind that there are certain food limitations.

How Is Invisalign Made?

Knowing how Invisalign is made is essential as it will help you to understand how the product works.

The first step is that your dentist or orthodontist will take some x-rays and digital scans of your teeth in order to determine what kind of treatment should be taken with your teeth.

Once this is done, the x-rays and scans are then sent to Invisalign’s lab, where they will create your clear aligners using the measurements that are provided in the scans and according to the treatment plan you have in place with your dentist.

Once Invisalign have made your aligners, they will either be sent directly to your door or to your dentist or orthodontist’s office, depending on your preference.

While having them sent to your door means that it is more convenient for you, having them sent to your dentist or orthodontist’s office means that they can be assured that the aligners fit properly and everything is ready to go.

There are numerous stages to wearing Invisalign, meaning that you will receive a new set of aligners to coincide with the positioning of your teeth at each stage. This ensures that your teeth are as comfortable as possible.
