Acrylic
- One of the most common material and can be used to produce a majority of TFL appliances.
- Appliances made in acrylic have the option to have ball clasps added.
- Can be relined and modified easily.
- Very hard rigid feel, which can be hard for patients to get use to.
- Available in clear, ice blue and pink.
True Comfort
- Easy to deliver and comfortable to wear.
- Commonly referred to as a Dual Laminate or Hard/Soft material, it is a thermoformed material with a soft inside and hard outer shell.
- Minor modifications can be made on this material, occlusal relines can be made easily but it can not be internally relined. Bonds to acrylic.
- Can be distorted if exposed to heat.
- Available in clear, blue and pink.
Thermoform
- Popular because appliances will be thinner and more compact.
- It is rigid, but not as rigid as acrylic.
- Material is not easy to modify, occlusal relines can be made easily but it can not be internally relined. Bonds to acrylic.
- Can be distorted if exposed to heat.
- Available in clear.
Thermoplastic
- A favorite among dentists for limiting the need for chair time.
- Is similar to standard acrylic, but if run under hot water it will become softer, allowing patients to easily seat their appliances.
- Mainly used for the fabrication of Nightguards, Deprogramers and Farrars.
- Bonds to acrylic and can be modified.

Milled PMMA
- Most popular digital material.
- Comparable to standard acrylic, it is rigid and very durable. A long lasting, digital alternative to 3D printed appliances.
- Final appliances look like polished glass giving it an expensive look.
- PMMA will not yellow over time.
- Can be easily modified since it bonds to acrylic.
- Available in clear.
Acetal
- Acetal is becoming a very popular digital material option.
- Strong, durable and semi-flexible resin.
- Typically used for tooth colored/metal free clasps, partial frame works and snap-on smiles.
- Durability of the material allows for an ultra compact appliance making it a favorite of patients.
- Once polished, appliances are smooth and white as opposed to the rougher texture of 3D printed materials.
- Acetal can not be modified, but is perfect for Occlusal guard, TMJ and TrueDorsal appliances.
