How Clear Aligners got to where they are now

Updated: Jun 16, 2021

Since the introduction of digital clear aligners in the late 19th century, we can see the transparent dental splint moving through many different stages. Most of the time, these were only small stages of development, so while they gradually contributed a small part to the evolution, they never led to a drastic change in the entire system.


The most common materials used to date in the manufacture of clear aligners are various types of polymers, polyurethanes and PETGs. These materials provide a modulus of elasticity that expands on the tooth surface, exerting adequate pressure on the teeth and creating tooth movement.


Patients typically wear each Clear aligner for one to two weeks at a time. In the case of K Clear, a wearing period of two weeks is envisaged. To date, aligners have been static plastic trays whose sole purpose is to exert pressure on the teeth.

Clear aligners accompany a patient 87% of his entire day. He lives with them, chews on them, cleans them, and after two weeks he throws them away. Because then it is the turn of the next splint. The daily wearing time of the Clear Aligners is almost 87% of the whole day into the night.
