When researching Invisalign, one of the most common and important questions is:
What are Invisalign made of?
Since Invisalign aligners are worn for most of the day, understanding the materials involved helps build confidence in both comfort and safety.
Below is a clear, professional explanation of what Invisalign aligners are made from and why the material matters.
What Material Is Used to Make Invisalign Aligners?
Invisalign aligners are made from a medical-grade, BPA-free thermoplastic material known as SmartTrack®.
This is not standard plastic. SmartTrack® is a proprietary Invisalign material developed specifically for orthodontic treatment.
The material is designed to be:
Safe for long-term oral use
Smooth and comfortable against gums
Flexible yet durable
Nearly invisible when worn
SmartTrack® plays a key role in helping aligners move teeth gradually and predictably.
What Is SmartTrack® Material and Why It Matters
SmartTrack® is engineered to improve both comfort and performance during Invisalign treatment.
Compared to traditional aligner plastics, SmartTrack®:
Provides a more precise fit
Applies consistent, gentle force
Feels smoother on soft oral tissues
This controlled flexibility allows teeth to move more efficiently while reducing unnecessary pressure. The result is a more comfortable experience throughout treatment.
Is Invisalign Material Safe for Daily Wear?
Yes. Invisalign aligners are designed to be worn 20 to 22 hours per day.
SmartTrack® material is:
Medical-grade
Biocompatible
BPA-free
Approved for extended oral wear
These qualities allow aligners to remain safe and comfortable throughout daily activities, including speaking and working.
How Invisalign Aligners Are Made
Invisalign aligners are created using advanced digital planning and custom manufacturing. Each step is designed for accuracy and comfort.
Digital Tooth Scans
High-resolution digital scans capture the exact shape, spacing, and position of each tooth. This creates a precise 3D model without traditional impressions.
Customized Treatment Plan
The digital model is used to build a personalized treatment plan. Each movement is carefully planned to guide teeth into alignment over time.
Series of Custom Aligners
A sequence of aligners is created instead of a single tray. Each aligner applies gentle pressure to move teeth step by step.
SmartTrack® Precision Molding
Each aligner is molded using SmartTrack® medical-grade thermoplastic. This material provides a secure fit, consistent force, and improved comfort throughout treatment.
Invisalign vs Other Clear Aligners: Material Differences
Not all clear aligners are made with the same materials.
Some alternatives rely on generic plastics, which may feel stiff or lose shape more quickly.
Invisalign stands apart because:
SmartTrack® is exclusive to Invisalign
The material offers improved flexibility and durability
Tooth contact and control are more consistent
These material advantages contribute to both comfort and treatment effectiveness.
