State of the art clear aligners

Effective teeth straightening

As a market leader, we have tailored our clear aligner service to give you endless possibilities. You could now decide either to benefit from our well-known K Clear brand or even build your own brand. We will be always there to support you with state-of-the-art clear aligners and exquisite service.

How to start



You will gain access to our portal for doctors. There you can easily upload clinical photos and X-rays of your patient. You can send us impressions you made of your patient’s teeth by post. 



About 3-5 days after all necessary documents have been received and accepted by us, we will send you a first treatment plan, which includes a 3D simulation of the results. This plan shows the teeth movement needed and is developed by dental professionals, who exactly know about the pressure and unique design of our Aligners, for each patient individually.

Due to our 3D simulation you can already show your patient the final result at this stage. Furthermore, the treatment plan gives an overview over the treatment duration.


Clear Aligners

After you have accepted the treatment plan, the Aligners for your patient will be produced. This usually takes 12 working days of production. So you are going to receive your Aligners not later than 3 weeks after you have confirmed the plan.
