What is Tristar Trubalance?

Tristar TruBalance is an advanced multilayer thermoforming material developed for the fabrication of active clear orthodontic aligners.

Unlike conventional single-layer PETG sheets, TruBalance uses a composite sandwich construction that combines a rigid engineering-resin core with tough, flexible outer layers. This carefully balanced structure helps the aligner maintain clinically useful orthodontic forces while remaining comfortable, clear, and resistant to cracking during fabrication and everyday patient use.

Designed for active tooth movement, TruBalance gives orthodontists and dental laboratories a reliable material for producing aligners that fit closely, retain their shape, and deliver soft, consistent forces throughout the recommended wear period.

Why Choose Tristar TruBalance?

Multilayer Composite Technology

TruBalance combines different material properties within one sheet:

• A rigid composite core supports force retention and dimensional stability.
• Flexible outer layers improve toughness, comfort, and impact resistance.
• The multilayer construction reduces the permanent deformation commonly associated with basic single-layer thermoforming materials.

This combination provides the balance needed between mechanical performance and patient comfort.

Superior Force Retention

Clear aligners must continue applying controlled orthodontic pressure after several days of wear. Materials with high stress relaxation may lose a significant part of their initial force, reducing the effectiveness of the planned movement.

According to Tristar’s simulated testing, TruBalance can maintain up to 90% of its original designed force over a 10-day period. This supports more consistent force delivery when the aligner is manufactured correctly and used with an appropriate digital treatment plan.

High Crack and Impact Resistance

Aligners may crack during removal from the model, trimming, insertion, removal, or normal patient use.

TruBalance is engineered with a tough polymer structure that provides high impact strength and resistance to cracking. Its impact resistance has been evaluated using ASTM D5420, a standard test method for the impact resistance of flat, rigid plastic specimens.

Reduced breakage can mean:

• Fewer aligner remakes
• Less wasted laboratory time
• Fewer emergency patient visits
• Lower material and production costs
• A more reliable patient experience

Tough Yet Flexible

TruBalance is designed to absorb energy and flex without fracturing. The manufacturer reports that the material can stretch to approximately three and a half times its original dimension before breaking under test conditions.

This toughness is particularly useful during aligner removal, trimming, finishing, insertion, and repeated daily handling.

Clear and Stain Resistant

TruBalance offers excellent transparency for discreet orthodontic treatment. It also provides strong chemical resistance against common staining substances such as:

• Coffee
• Tea
• Toothpaste
• Mouthwash
• Oils
• Mustard and strongly coloured foods

Patients should still be advised to remove their aligners before eating or drinking anything other than water.

Comfortable, Close Adaptation

The material produces a thin, snug appliance that adapts closely to the dental model when processed correctly.

Its flexible outer structure helps improve comfort during insertion and removal while maintaining the rigidity needed for controlled tooth movement. A comfortable fit may also make it easier for patients to follow the prescribed daily wear schedule.

Storage Instructions:

• Store unused sheets in their original sealed packaging.
• Keep the product in a cool, clean, and dry location.
• Protect it from moisture, excessive heat, and direct sunlight.
• Reseal the pouch immediately after removing a sheet.
• Avoid storing near chemicals, solvents, steam, or strong odours.
• Use clean, dry gloves when handling.
• Follow the expiry date printed on the original packaging.
• Apply first-expiring, first-out inventory management in the laboratory.
