Clear aligners have transformed the orthodontic experience, offering a discreet, comfortable way to straighten teeth without the wires and brackets of braces. Among the top clear aligner systems are Spark Aligners and Invisalign — both widely used by orthodontists and known for producing excellent results.
But how do you decide which option is best for you?
This guide offers a complete comparison of Spark Aligners vs Invisalign, highlighting key differences and similarities in comfort, effectiveness, appearance, and more. Whether you're starting your research or narrowing down your choices, this side-by-side breakdown can help you feel more confident about your treatment decision.
What Are Spark Aligners?
Spark Aligners are a newer clear aligner system developed by Ormco — a global leader in orthodontic technology. Spark trays are made from a proprietary material called TruGEN™, which is known for being ultra-clear, stain-resistant, and gentle on the gums.
Spark Aligners are only available through trained orthodontists, ensuring personalized oversight throughout your treatment.
What Is Invisalign?
Invisalign was the first major brand to introduce clear aligners and remains one of the most recognized options today. These trays are made from a patented thermoplastic called SmartTrack®, designed for precise movement and consistent wear.
Invisalign is also administered through dental professionals, though not all providers are orthodontic specialists.
