### Tri-laminar Construction
FlexrPro™ comprises three distinct layers - an inner elastomeric layer sandwiched between two thinner and more rigid elastic shells.

The characteristics of tri-laminar materials today are considered the industry gold standard of care in the clear aligner space.

The inner elastomeric layer provides the exceptional flexibility and rebound characteristics, while the rigid double shell provides the impact protection while closely adapting to the tooth surface to facilitate even complex tooth movements such as intrusion, extrusion and rotation.

### Consistent Forces
In contrast to single layered materials that are unable to offer consistent tooth moving forces over a period of time due to deformation, the tri-laminar FlexrPro™ aligner material is setting new standards in continuous force transmission characteristics.

Single layered aligner materials exert high initial force and tend to rapidly degrade and lose their effectiveness.

The elastomeric inner core with the double shell rigid protective outer layers exert a lower initial force but maintain the optimal force consistency over sustained treatment periods.

### Recovery From Deformation
Impact from occlusal forces lead to aligner deformation during wearing time. This deformation also reduces the aligners' tooth movement effectiveness. With standard single layered aligner materials, the loss of tooth movement effectiveness due to permanent deformation can amount to as much as 50% during the first days of aligner wearing.

The inner elastomeric core of the tri-laminar FlexrPro™ construction with its enhanced elastic properties significantly prevents the permanent deformation from forces over a much longer period of time.

The ability of FlexrPro™ to bounce back and not deform under occlusal forces, translates to a 72% more effective tooth movement characteristic as compared to a singly layered material, resulting in more predictable and continuous forces during the aligner treatment period.

### Enhanced Patient Comfort
FlexrPro™ with its inner elastomeric core offers a higher degree of flexibility that facilitates a much more intuitive, comfortable and easy aligner insertion. The patient experience due to the significantly lower insertion forces as compared to standard aligner materials renders the treatment more comfortable and convenient. Gentler forces and more effective tooth movement with FlexrPro™ is a practice builder and valuable endorsement for painless and comfortable aligner treatments.

The flexibility and rebound characteristic of the inner elastomeric core also ensures crack resistance, protection from impact and a more comfortable tooth to tooth occlusal contact experience during aligner wearing time.

### Clarity & Stain Resistance
The regularity of the molecular structure of FlexrPro™ allows light rays to pass through without much diffraction, deflection or scatter resulting in one of the most clear and transparent aligner materials on the market.

The densely packed structure of the double outer shell ensures stain resistance even in coffee for upto 6 days.

The double foil protection on the FlexrPro™ discs ensures no scratches or contamination on the final aligner until the final process of margin trimming is complete. The outerfoil is removed just prior to aligner final packaging for delivery.
