Nearly invisible teeth straightening with clear aligners – We design your perfect smile


Speedy service and very good scientific based work

Dr. Alexander Ilbag, Salierpraxis, Düsseldorf

I am treating my patients with Aligners since more than 14 years now. K Line is probably the best scientific based Company which comes with a very affordable price.

Dr. Pouran Vali-Pursche, Kieferorthopädie Meerbusch

Located in the WDR Arcaden in the center of the city of Cologne we have a lot of clients from the media. The always stable consistency of results is what we love mostly about K Line. Our patients can be sure that they are getting the best treatment option that is possible.

Dr. Nora Heuser & Dr. Mathias P. Sommer, Praxis WDR Arkaden, Cologne

What we like most about K Line is the dental support and the service. The exchange of the information is very good. The results are always as expected.

How does it work?

Teeth straightening has never been that easy:

  1. Snap the K Clear Aligner over your teeth.
  2. Teeth move according to previously planned tooth movement by our Orthodontic specialists on 3D designing softwares.
  3. After nearly each week, the K Line Europe Clear Aligner is changed to the following one in the correct sequence.

Voila! You get the straight teeth you’ve always wanted!
