Keeping it simple was the hard part. Our retainer is pure PHA. No additives, plasticizers, colorants, or stabilizers. PHA is edible.
Glucose, a simple sugar, feeds the bacteria that produce PHA.
Bacteria ferment sugars into PHA, the polymer we recover and form into the retainer.
PHA is recovered from inside the cells and purified through several rounds to remove impurities.
We check the polymer’s purity, molecular weight, and how it responds to heat and force.
We form the PHA into thin discs, then heat and shape them over a model of your teeth.
PHA Production
Manufacturing can introduce unexpected kinds of contamination. We make sure that isn’t happening with our products using independent labs, and publish the results.

When simulating regular use, we found that retainers release at least 100k particles into your body a year.
Using a simulated gut environment, our material digested completely within a few weeks. PETG barely degraded in the same timespan.
