Glee Aligners (formerly known as Denkalign) offer cutting-edge, multi-layered clear aligners that are proudly manufactured entirely in Germany. We created this article to answer one of the most common questions about aligner quality and performance, from both a dentist’s and a patient’s perspective.
Our aligners are crafted from Zendura-FLX, a premium material recognised for its outstanding performance and durability. This advanced material stands out in the clear aligner market due to its innovative dual-shell, three-layer structure:
The outermost shell provides exceptional resistance to wear, acting as a protective barrier against grinding and bruxism forces that can affect aligners over time.
The inner shell is strong and resilient, designed to securely hold onto the teeth. This ensures a consistent, controlled force is applied to guide teeth into alignment with precision.
Between the inner and outer shells lies a central elastomeric layer that gives the aligner its elasticity.
This middle layer plays a critical role in preventing deformation, which is a common issue with many aligners after repeated insertion and removal. Thanks to this unique structure, our aligners apply a gentler force when first inserted, followed by elastic recovery that generates effective tooth-moving pressure over time.
The result is a high-performance aligner material that supports excellent clinical outcomes and improved patient satisfaction.
Our manufacturing process includes strict quality control at every stage, ensuring each aligner meets the highest standards—unlike some providers where consistency may vary.
For patients, this advanced material and design translates into a more comfortable and effective treatment experience:
Virtually invisible aligners, so only you know you’re wearing them
Gentle, pain-minimising force for improved comfort
Efficient teeth straightening in the shortest possible time
Custom-made trays produced using precise 3D technology
Each clear aligner tray is labelled in sequence and is typically worn for around two weeks before progressing to the next step in your smile journey.
Glee Aligners apply up to 40% less force upon insertion compared to many other aligner materials. This ensures superior comfort throughout treatment, while still delivering consistent, reliable tooth movement that both dentists and patients can trust.
