Although clear aligners can be made with several types of thermal forming material, Great Lakes recommends Great Lakes ComfortTrack™.
Great Lakes ComfortTrack™ material is specially designed for clear aligner therapy. It features high performance elastomeric properties that generate ideal initial force to gently move teeth and high strength resiliency to maintain tooth movement.
Compared to other clear aligner materials, Great Lakes ComfortTrack's multi-layer construction generates 40% less initial force for reduced patient pain, and retains 150+% greater force on day seven. The result is superior patient comfort and more effective, predictable tooth movement.
