Invisacryl™ T Clear 0.76mm/125mm - Round (100/pkg)

A unique thermal plastic polyurethane material, Invisacryl™ T, is more elastic, flexible, and crack-resistant than other materials. It is stronger and more durable, making it ideal for aligners, finishing appliances, and bite guards.  

Invisacryl™ T offers:

Patient Comfort & Compliance¹

Single-layer TPU’s soft, elastic feel makes insertion and removal easy — patients are far more likely to wear a comfortable retainer consistently. Better wear = better outcomes.

Fewer Remakes, Lower Costs³

TPU’s ductile elastomer properties mean it bends without fracturing — dramatically reducing costly remake requests from cracked PETG retainers.

Stability Under Repeated Wear²

Unlike single-layer PETG, single-layer TPU maintains a stable elastic modulus through thermocycling — meaning its properties hold up across weeks of daily insertion and removal.

Simple, Predictable Thermoforming

Single-layer TPU is reported to more accurately reproduce mold shapes than other materials⁴ — the handling characteristics differ from PETG, reflecting the material's higher performance. A small adjustment in workflow delivers a significantly better end result

Ideal Clinical Cases for Invisacryl™ T

• Patients prone to fracturing single-layer PETG retainers³
• Deep-bite cases at elevated risk of retainer breakage³
• Teenagers and active patients with demanding lifestyles
• Post-aligner retention cases requiring elastic, form-stable retention
• Patients who struggle with stiff appliances (compliance cases)¹
• Labs seeking a single-layer upgrade over PETG⁴
