About retainer blanks
A retainer blank is a clear sheet thermoformed over the model to make a retainer. Essix-type retainers are made from thermoplastic polymers of two kinds, amorphous and semi-crystalline.
Essix-type retainers are clear thermoplastic removable retainers. Vacuum-formed and Hawley retainers are the most commonly used removable retainers.
How the retainer sheets on this shelf differ
- Retainer Blanks — The clear sheet a retainer is formed from.

What to look at when choosing a retainer material
Stiffness and wear: in a study of four Essix-type materials, the polypropylene material was the most flexible, and wear and water absorption differed between materials.
Properties change in forming: one study concluded that the physical and mechanical properties of thermoplastic materials should be evaluated after thermoforming.
Size and gauge: sheets are listed by thickness, by shape (5 inch square or round) and by pack count.
