Built by Clinicians, Backed by Science
Dr. Abhiyanth Shetty (New Zealand) and Dr. Akhil Shetty (India) have treated thousands of patients and tested various materials in real-world clinical settings across two continents. This multi-layer sheet consistently delivered the best results — making it the preferred choice for Route to Smile Aligners.

Core Material Properties at a Glance
This table summarizes key mechanical and physical properties relevant to aligner performance. While all materials listed here have similar dimensions, the differences in stress handling, force decay, and tear strength can significantly impact clinical outcomes.
Each of these key material properties is explained in detail on the following pages — with context, and insights to help you understand what matters most in clinical performance.

1. Yield Stress (MPa)
What it means?
Strength of the material before it begins to permanently deform.
Why it matters?
Higher yield stress ensures the aligner holds its shape longer, maintaining consistent force throughout wear.
What to look for?
High yield stress is ideal — It means better durability and force retention during the treatment cycle.
Route to Smile Aligners:
Have high yield stress leading to better durability and force retention during the treatment cycle.
Have high yield stress leading to better durability and force retention during the treatment cycle.
2. Yield Strain (%)
What it means?
How much the material can stretch before it deforms
Why it matters?
This impacts how well the aligner adapts to the teeth and comfort during wear.
What to look for?
Moderate to high yield strain is ideal
Route to Smile Aligners:
Have high yield strain allowing optimal balance of stretch and structure.
Have high yield strain allowing optimal balance of stretch and structure.

3. Tensile Modulus (MPa)
What it means?
A measure of stiffness when the aligner is pulled or stretched
Why it matters?
Stiffer materials transmit more force but need to be comfortable.
What to look for?
Moderate to high values are preferred — for effective force with comfort.
Route to Smile Aligners:
Are engineered to deliver controlled, consistent force.
Are engineered to deliver controlled, consistent force.
4. Flexural Modulus (MPa)
What it means?
Stiffness during bending — important when the aligner is under bite pressure.
Why it matters?
Prevents deformation during chewing or clenching.
What to look for?
High flexural modulus is ideal — ensures better shape retention and force consistency.
Route to Smile Aligners:
Have high flexural modulus making it strong and stable under stress.
Have high flexural modulus making it strong and stable under stress.

5. Angle Tear Strength (kN/m)
What it means?
Resistance to tearing when stress is applied at an angle (e.g., during insertion/removal).
Why it matters?
Helps reduce aligner breakage and improves confidence in daily use.
What to look for?
High tear strength is ideal — increases aligner life and patient ease-of-use.
Route to Smile Aligners:
Have high tear strength leading to superior toughness and durability.
Have high tear strength leading to superior toughness and durability.
6. Tensile Force Decay (%)
What it means?
Loss of force after being in a wet, warm environment (like the mouth).
Why it matters?
The lower the decay, the better the aligner holds effective force during wear.
What to look for?
Low decay is ideal — ensures sustained force between changes.
Route to Smile Aligners:
Have low decay maintaining effective force longer than typical materials.
Have low decay maintaining effective force longer than typical materials.

7. Initial Tensile Force (N)
What it means?
The initial force the aligner applies when first worn.
Why it matters?
Needs to be high enough to move teeth, but not so high that it causes pain or trauma.
What to look for?
Moderate force is ideal — effective but gentle.
Route to Smile Aligners:
Have balanced force for comfort and clinical results.
Have balanced force for comfort and clinical results.

24h Tensile Force Decay in 37℃ Water
Route to Smile Aligners:
Demonstrates excellent force retention, holding effective levels of force for longer compared to typical materials — supporting consistent tooth movement and reducing the risk of overcorrection or lag.
