<s>[INST] Invisalign is a brand of clear orthodontic aligners.
Invisalign aligners are made from a unique and proprietary thermoplastic material called SmartTrack.
The thermoplastic material is designed to provide a constant, but gentle pressure that shifts the teeth into a new position.
The aligners are custom-made for each individual's teeth.
The design and manufacturing process of Invisalign aligners uses advanced computer technology, including 3D printing.
This enables the creation of a virtual treatment plan with a set of aligners that are tailored to an individual's specific orthodontic needs.
The virtual treatment plan is also used to predict the movement of teeth during the treatment process.
The first Invisalign aligner is typically worn for about two weeks, during which time it applies the desired pressure to move the teeth.
The aligner is then replaced by a new one, which applies a slightly different pressure to further shift the teeth into the new position.
The process is repeated with each new aligner until the desired orthodontic result is achieved.
Some advantages of using Invisalign aligners are that they are less noticeable than traditional metal braces.
They also allow for easier cleaning and oral hygiene practices, and are generally less painful than traditional braces.
In addition, Invisalign aligners can be removed for eating, drinking, and other activities.
This makes it easier to maintain good oral hygiene and to eat foods that might be problematic with traditional braces.
