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.

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.

Kieferorthopädin aus Meerbusch

Our doctors now have a system where they can lay their trust in treating cases with Clear Aligners which was missing till now. I thank the team of K Line for their support which has helped us make K Clear the No.1 Clear Aligner in India.

Dr. Swapnil Gupta, India

I have treated patients with Clear Aligners for many years now and K-Line is the fastest and most effective system that I have used! The support provided by Dr. Kandil and the rest of the team is the best I have received from any aspect of dentistry.

Dr. David Hardiman, British Dental Center, UAE

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.

Praxis in Cologne

After using clear aligners alongside other orthodontic systems for many years now I have found K Line to be the most effective, scientifically based system available. The team are knowledgeable and always very helpful. K Line has proved to be a very reliable company for myself and my patients.

It is not just about the quality of the software or the material, the reciprocity of the K Line Team sets them apart.

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!
