Choosing a clear retainer material is not only about finding the cheapest sheet.
Different brands vary in material composition, thickness, clarity, durability, thermoforming behaviour and price. A material that works well for a high-volume dental lab may not be the first choice for a clinic looking for premium long-term retention.
To make the comparison easier, here are five well-known retainer brands and how they differ in manufacturing origin, price, quality and product specifications.
Prices below are approximate reference prices in USD per sheet. Actual pricing can change depending on distributor, thickness, sheet size and order quantity.
Quick Comparison of 5 Retainer Brands
| Brand | Manufactured In | Common Specification | Approx. Price Per Sheet | Best Suited For |
|---|---|---|---|---|
| Keystone Industries — Pro-Form | USA | Around 0.75 mm | From $0.50 | Budget-conscious, high-volume production |
| Dentsply Sirona — Essix ACE | USA | Around 0.75–1.0 mm | $2.15–$3.00 | Familiar everyday retainer workflows |
| SCHEU-DENTAL — DURAN | Germany | Around 0.4–1.0 mm | $2.75–$3.35 | Clear, rigid thermoformed retainers |
| Zendura Dental — Zendura A | USA | Around 0.76–1.02 mm | $4.00–$4.70 | Premium durability and long-term retention |
| ERKODENT — Erkodur | Germany | Around 0.6–1.0 mm | Around $4–$5+ | Material and thickness flexibility |
From a price perspective, Keystone Pro-Form is generally the cheapest option in this comparison, especially when purchased in larger quantities.
At the other end, Zendura A and some Erkodur options sit in the premium price range.
That does not mean the most expensive material is automatically the best. The right choice depends on what matters most for the case: cost, durability, clarity, workflow or material flexibility.
1. Keystone Industries Pro-Form — Best for Budget-Conscious Production
If material cost is one of your biggest considerations, Keystone Pro-Form is worth looking at.
Manufactured in the USA, Pro-Form retainer sheets are designed for orthodontic retainer fabrication and are available in clear and super-clear versions.
A common specification is approximately 0.75 mm thickness, with 5 × 5-inch sheets widely available.
Depending on pack size and material type, larger-volume orders can bring the cost down to approximately $0.50–$0.60 per sheet, although smaller packs or super-clear versions may cost more.
This makes Pro-Form particularly attractive for laboratories producing a large number of retainers.
The trade-off is that some clinics may prefer more premium materials when long-term material performance is a bigger priority than cost.
Best suited for
Dental laboratories and clinics looking for a practical, lower-cost retainer material for regular production.
2. Dentsply Sirona Essix ACE — A Familiar All-Round Retainer Material
Essix ACE is one of the most recognizable names in the clear retainer market.
It is manufactured in the USA and is commonly available in thicknesses around 0.75 mm, 0.875 mm and 1.0 mm.
Current market pricing typically places Essix ACE around $2.15–$3.00 per sheet, depending on thickness and distributor.
One of the reasons Essix remains popular is simple: many dentists, orthodontists and dental technicians are already familiar with the Essix retainer workflow.
It does not necessarily stand out as the cheapest or most premium material, but it offers a good middle ground between cost, familiarity and ease of use.
That makes it an easy choice for clinics that want a dependable material without changing their existing thermoforming process.
Best suited for
Practices that prefer a familiar and established clear retainer material for routine cases.
3. SCHEU-DENTAL DURAN — Strong Choice for Laboratory Thermoforming
DURAN is produced by SCHEU-DENTAL in Germany and is widely used in professional dental thermoforming.
It is known as a hard, highly transparent material suitable for orthodontic appliances, including clear retainers.
Depending on the application, DURAN is available across several thicknesses, commonly ranging from approximately 0.4 mm to 1.0 mm for retainer-related use.
Typical pricing is around $2.75–$3.35 per sheet.
DURAN becomes especially attractive for laboratories already working with systems such as BIOSTAR or MINISTAR, because it fits naturally into that thermoforming workflow.
Compared with a budget material such as Pro-Form, it costs more, but laboratories may value its consistency, clarity and established position in professional thermoforming.
Best suited for
Dental laboratories that want a clear and relatively rigid thermoforming material within an established laboratory system.
4. Zendura Dental Zendura A — Premium Choice for Durability
Zendura A sits noticeably higher in the price range, but it also targets a different type of user.
Manufactured in the USA, Zendura A is based on a proprietary thermoplastic polyurethane developed for orthodontic applications.
Common options include approximately 0.76 mm and 1.02 mm thicknesses, with pricing usually around $4.00–$4.70 per sheet.
The main attraction is durability.
Zendura is designed around characteristics such as elastic recovery, dimensional stability, impact resistance and resistance to repeated insertion and removal.
For a clinic or laboratory where long-term material performance matters more than the lowest possible cost per appliance, that can justify the higher price.
In other words, Zendura is not trying to compete with Pro-Form on price. It sits more naturally in the premium retainer material category.
Best suited for
Clinics and laboratories that prioritise durability, material stability and long-term retention.
5. ERKODENT Erkodur — Best for Material Flexibility
Erkodur is manufactured by ERKODENT in Germany and is another established name in dental thermoforming.
Unlike a brand that focuses on one main retainer sheet, ERKODENT offers a broader thermoforming system with different materials and thicknesses.
For retainers, Erkodur PETG is commonly used in thicknesses around 0.6–1.0 mm, depending on the desired appliance characteristics.
Pricing typically falls around $4–$5 or more per sheet, depending on thickness, size and distributor.
Its real advantage is flexibility rather than simply being the clearest or cheapest option.
A laboratory that works with several types of thermoformed appliances may appreciate being able to choose different ERKODENT materials for different indications.
Best suited for
Laboratories that want more control over material selection, thickness and thermoforming behaviour.
Which Retainer Brand Is the Cheapest?
Based on typical current pricing, Keystone Pro-Form is the cheapest option in this comparison.
When purchased in high-volume packs, the price can fall to around $0.50 per sheet, making it especially attractive for laboratories with a high production volume.
By comparison:
-
Essix ACE: around $2.15–$3.00 per sheet
-
DURAN: around $2.75–$3.35 per sheet
-
Zendura A: around $4.00–$4.70 per sheet
-
Erkodur: around $4–$5+ per sheet
This difference can become significant when hundreds of retainers are produced every month.
However, the cheapest material is not necessarily the most cost-effective for every clinic. If a more expensive material offers the characteristics you need for a particular workflow, the additional cost may still make sense.
Which Retainer Brand Is the Most Expensive?
In this comparison, Zendura A and certain Erkodur configurations generally sit at the premium end of the price range.
Zendura A can reach approximately $4.70 per sheet, while some Erkodur options may cost $5 or more per sheet depending on the specification.
The higher price reflects different material properties and manufacturing systems rather than simply branding.
For example, a practice choosing Zendura may be paying more for durability and elastic recovery, while a laboratory choosing Erkodur may value the wider range of material options.
So instead of asking which material is the most expensive, it is more useful to ask:
Which material offers the right balance of price, durability, clarity and workflow for your retainer cases?
Which Clear Retainer Material Should You Choose?
There is no single answer for every clinic or laboratory.
If your priority is low material cost, Keystone Pro-Form is one of the strongest options.
If you want a familiar and balanced everyday material, Essix ACE remains an easy choice.
For laboratories already using German pressure-forming systems, DURAN fits naturally into that workflow.
If long-term durability is more important than cost, Zendura A is one of the more premium options.
And if you want more flexibility in material and thickness selection, ERKODENT Erkodur gives you more room to tailor the thermoforming process.
But whichever retainer material you choose, there is another step that should not be overlooked.
The retainer still needs to be properly finished.
Retainer Material Is Only Half the Workflow
After thermoforming, a clear retainer usually requires trimming, contouring, edge refinement and polishing.
Even a premium material can feel uncomfortable if the margin is left rough, uneven or poorly finished.
This is where the MR.BUR Essix Retainer Contouring and Polishing Kit HP fits into the workflow.
The kit is designed to support the finishing process after thermoforming, helping dental technicians move from initial trimming to a smoother and more refined retainer edge.
It can be used as part of the finishing workflow for different thermoforming films, rather than being limited to only one retainer brand.
Whether you work with Essix, Zendura, DURAN, Erkodur or another retainer material, the final finishing stage remains important for producing a clean and comfortable appliance.
