Tristar multi layer thermoforming aligner Sheet 0.76mm*125mm - 10 sheets/pack

The Tristar Multi-Layer Thermoforming Aligner Sheet (0.76mm x 125mm, 10 sheets/pack) is a composite clear aligner material engineered by Whitesmile Clear (South Korea) for practices and labs fabricating clear aligners and retainers in-house. Unlike single-layer PETG sheets, Tristar combines a rigid engineering resin core with elastic outer layers for more consistent, longer-lasting orthodontic force.

Clinical Uses

• In-house fabrication of clear aligners for first-order alignment through more complex torque and vertical control movements
• Cases where consistent force delivery over the full wear cycle is a priority
• Practices using pressure- or vacuum-forming equipment such as BioSTAR, MiniSTAR, or Drufomat

Key Features

• Multi-Layer Composite Construction — rigid engineering resin core with elastic layers, unlike single-layer PETG materials
• Superior Stress Retention — retains significantly more orthodontic force over the wear cycle than typical single-layer aligner materials
• Crack Resistance — tough polymer backbone resists cracking during forming, insertion, and removal (impact strength tested per ASTM D5420)
• Chemical Stain Resistance & Clarity — stays clear and resists staining through normal wear
• Compatible with Standard Pressure-Forming Equipment — works with BioSTAR, MiniSTAR, Drufomat, and similar machines

FAQ

Why choose a multi-layer aligner sheet over single-layer PETG?
Single-layer materials like PETG can lose a large portion of their force delivery within the first hours of wear as the plastic behaves partly like a fluid; Tristar's composite, multi-layer construction is designed to retain force more consistently over the full wear cycle.

What thickness should I use for active aligners vs retainers?
Thinner sheets like this 0.76mm option are typically used for active tooth-moving aligners, while thicker sheets (such as 1.00mm or 1.80mm) are more common for retention-phase appliances or cases needing extra rigidity.

What equipment do I need to form this sheet?
Standard dental pressure- or vacuum-forming machines such as BioSTAR, MiniSTAR, or Drufomat are compatible with Tristar sheets.

Does the material resist cracking during forming?
Yes, Tristar's tough polymer backbone is specifically engineered for crack resistance during mold removal and normal patient use, addressing a common complaint with older single-layer materials.
