What Material Are Invisalign Clear Aligners Made Of?

Invisalign® allows people to straighten their teeth without needing the metal brackets and wires with conventional braces. Invisalign trays are transparent and almost undetectable on the teeth. However, what exactly are those trays composed of? Continue reading to discover more about how the trays' material and design move your teeth around.

What are Invisalign aligners made of?

Invisalign clear aligners, often known as Invisalign braces, are transparent trays composed of a plastic substance. Over the last few years, Invisalign has grown in popularity, and it is currently one of the most popular teeth straightening options available by the orthodontist. The benefit of clear aligner therapy is that it enables patients to correct mild to moderate malocclusions discreetly, which makes it perfect for people who might be uncomfortable with the appearance of traditional metal braces.

The custom-made Invisalign trays are made of SmartTrack, a proprietary thermoplastic material known as polyurethane resins. These resins are a mixture that is exclusive to Invisalign. The substance is comparable to plastic; however, it was created especially to assist in the gradual shifting of teeth. They have a high molecular weight and are of medical quality.

One of the most important aspects of Invisalign's success is the SmartTrack material. The material is transparent, allowing the natural teeth to show through, so the aligners are hard to notice. Furthermore, the material used in Invisalign aligners is robust, long-lasting, and effective in progressively straightening teeth.

This material is biocompatible and powerful enough to move teeth gradually with concentrated pressure, yet it is also pleasant enough to wear without discomfort. Plus, since this material is transparent, patients can talk and smile with confidence during their treatment.

How Invisalign aligners are made

The orthodontist will take x-rays and digital scans of the patient's teeth to begin the treatment and to determine the best orthodontic option to align the teeth. This information is then forwarded to the Invisalign lab, where the aligners will be custom-made based on the treatment plan's exact requirements.

The aligners are sent directly to the patient or the orthodontist’s office after the production process is complete. Patients can start the Invisalign treatment once they receive their aligners. Invisalign is often more pleasant than fixed metal brackets and wires because they fit the teeth precisely at each step of the process.

Eligibility for Invisalign

Invisalign clear aligners may help many people. The only way to determine whether this is a viable option is to meet with an orthodontist to discuss treatment options. Invisalign may typically correct crowded teeth, gapped teeth, as well as overbite, underbite, and crossbite.
