NEXT  GENERATION COMPOSITE   ALIGNER  MATERIAL

KEY FEATURES: STRESS RETENTION

Stress retention refers to the propensity of a material to resist permanent deformation under an applied load.

The Tristar material achieves this by using polyurethane as it’s composite core. This ensures that the material continues to deliver forces consistently and exhibits mostly elastic behaviour throughout the application time.

Most of the other commercially available materials are made of polyester material using only PETG as its base resin. Tristar is made using rigid engineering resin at the composite core with superior stress retention and cracks resistant properties.  In addition to being tough and durable, this material performs exceptionally well in aligning patients’ teeth. Its other significant benefits include superior chemical stain resistance and clarity.

CRACK RESISTANCE

Cracking can occur when removing an appliance from a forming mold, or by a patient when in use. Tristar having a tough polymer backbone, has a reputation as the benchmark for crack resistance.  Plastics toughness and crack resistance can be evaluated by measuring Impact Strength.

Over a decade of experience in fabricating clear aligners have demonstrated that demands in clear aligner movement have increased, from simple first order alignment to complex torque movements as well as vertical control.

TRISTAR IS MADE USING RIGID ENGINEERING RESIN AT THE COMPOSITE  CORE  WITH  SUPERIOR STRESS  RETENTION  AND  CRACK RESISTANT   PROPERTIES

KEY FEATURES: STRESS RETENTION

Original clear aligners were single layered materials or simple dual-layered materials. These were often either polyurethane, a flexible or tough material, or based on Polyethylene terephthalate glycol, commonly known as PETG.

These original formulations had various compromises. Polyurethane, although tough, often proved to be too stiff. PETG, although aesthetic, had fairly poor crack resistance and often users would complain of aligner breakage upon insertion or removal.

By far the biggest compromise was the fact that all single-layer plastic materials exhibit fluid properties. A portion of the plastic sheet behaved like an elastic, rebounding back to its original form, but a large percentage of the plastic sheet behaved like a fluid, causing permanent deformation and lack of force consistency. Current single layered materials lose up to 50% of their ability to deliver the same force over the first 8 hours of application of the aligner.

The elastic, central layers allow the outer composite layers to slide over each other, aiding extended elastic properties.

Our new generation of aligner material overcomes these difficulties by providing a composite sandwich, which in combination, provides high impact strength, yet remains flexible and comfortable for your patients. Essentially, this material has minimal fluid behaviour and maximum elastic behaviour. The force consistency when applied intraorally is amongst the highest of all commercially available clear aligner materials.

Tristar is all about delivering appropriate forces – when the right clear aligner design and treatment plan is applied, Tristar clear aligner materials provide maximum comfort and maximum confidence for both patients and doctors.

change the aligner, the tooth movement is lagging behind the aligner stage design.

WITH TRISTAR:

In this clinical example, excellent tracking between the clinical outcome and the aligner simulation has been achieved. Each aligner maintains consistent force throughout the wear period, enhancing tooth movement and reducing side effects.

KEY FEATURES: STRESS RETENTION

Tristar aligner is economical, yet effective. Reduce broken/cracked aligner issues, with best in class performance. A composite core with a tough, yet flexible outer shell, Tristar will outperform all single layer aligner materials.

When compared with competing for composite tray materials, Tristar outperforms them, comfortably, whilst being cheaper, significantly.

The key factor behind the delivery of orthodontic force is consistent, soft force delivery. Composite sheets like Tristar will be the way forward for clinicians to deliver effective tooth movement with clear aligners. The best way to experience this material is to ask for your free sample, today!

Clinical results may vary. Medical Device registration approval pending in certain export markets.

A  COMPOSITE  CORE  WITH  A  TOUGH,  YET  FLEXIBLE  OUTER  SHELL, TRISTAR  WILL OUTPERFORM  ALL  SINGLE  LAYER  ALIGNER  MATERIALS.
