Erkodent Retainers

Erkodent provides a superior alternative not only for nightguards (please see the Comfort H/S Splint page) but also for your clear retainers.

Most of the material currently on the market is essentially a cheap plastic, the same as that used to package fresh produce at the grocery store. Erkodent is different. The German engineered material is ISO approved and BPA free.

We use Erkoloc-Pro for the Comfort Splints. It has a soft interior and hard exterior and is available in various thicknesses from 1mm to 5 mm. Some doctors have loved the 2mm as an alternative for their patients who grind and we are currently testing the 1mm and 1.3mm hard/soft material as an option for clear retainers — they are far more comfortable for the patient and not as rigid so more durable.

Erkodur is the hard material and comes in various thicknesses as well, from .8mm to 5mm (with 1mm as the most common for clear retainers).

The difference is not only in the material, but also in the technology. We use the Erkoform-3D, a state of the art thermoforming unit specially calibrated to produce the ideal temperature and pressure for each type of material and thickness.

Erkodent provides your patients a product of exceptional quality. We invite you to check out the difference for yourself.
